Some notes on the translation of these original MERIDA operating instructions The illustrations on the first pages of the translation of these original MERIDA operating instructions show a typical MERIDA mountain bike and a typical MERIDA pedelec. One of these MERIDA bikes looks similar to the MERIDA mountain bike or MERIDA pedelec you have purchased. Today’s bikes and pedelecs come in various types that are designed for specific uses and fitted accordingly.
General safety instructions This symbol warns you of incorrect actions that could result in damage to property and the environment when using your MERIDA pedelec. Please note as well in all cases the general warning information given in the translation of these original operating instructions. S This symbol provides you with information about how to handle the MERIDA pedelec or refers to a passage in the translation of these original operating instructions that deserves your special attention.
Even a manual as big as an encyclopedia could not describe any possible combination of bike or pedelec models and components or parts on the market. The translation of these original MERIDA operating instructions therefore focuses on your newly purchased MERIDA mountain bike and MERIDA pedelec and standard components and provides the most important information and warnings.
Never ride under the influence of drugs, medication, alcohol or when you are tired. Do not ride with a second person on your MERIDA bike (except on a tandem) and never ride without having both hands on the handlebars. Observe the legal regulations concerning off-road cycling (e+f) and cycling on public roads with MERIDA bikes and MERIDA pedelecs. These regulations may differ in each country. Respect nature when riding through the forest and in the open countryside.
Intended use Categorie 3: Cross-country, marathon and tour mountain bikes MERIDA cross-country (b), MERIDA marathon and MERIDA tour mountain bikes (c) are also suitable for off-road use, but not for tricks, stair riding etc., training and competitive use in the categories freeride, dirt, downhill races. Keep in mind that every type of bike is designed for a specific use.
For your own safety, do not overestimate your riding skills. Please note that though looking easy the tricks of a professional are hazardous to your life and limb. Always protect yourself with suitable clothing. Due to the higher stresses, these MERIDA bikes should be checked for possible damage after every ride. Full suspension MERIDA bikes with medium suspension travel are typical for this category. Category 5: Dirt and freeride bikes MERIDA dirt bikes (g) are intended for harder use on secured terrain.
In general, all regulations that apply to bicycles also apply to MERIDA pedelecs (a-c). Inform yourself in the country where you use your MERIDA pedelec whether wearing a helmet is compulsory (d). Please note that wearing a helmet is compulsory in Australia. Please make sure you do not confuse your MERIDA pedelec with a “MERIDA speed pedelec” (see “Speed pedelecs”).
Most of the MERIDA speed pedelecs (e) are designed for cycling exclusively on lanes and roads with a smooth surface (f). Only use trails that are allowed for speed pedelecs / e-bikes. Typical MERIDA speed pedelecs are generally not suitable for off-road use. Using MERIDA speed pedelecs off-road can result in crashes with unforeseeable consequences.
Before your first ride 1. If you want to use your bike on public roads, it has to comply with legal requirements. These requirements may vary in each country. The fittings of your MERIDA bike are, therefore, not necessarily complete (a). Ask your MERIDA dealer concerning the laws and regulations applicable in your country or in the country you intend to use your MERIDA bike. Have your MERIDA bike equipped accordingly before using it on public roads. 3.
6. If you have bought a MERIDA bike with suspension (f+g), you should ask your MERIDA dealer to adjust the suspension mechanism to your needs before delivery. Improperly adjusted suspension components are liable to malfunction or damage. In any case they will impair the performance of your pedelec as well as your safety and joy whilst riding. For more information see the chapters “Suspension forks” and “Rear shocks” and the instructions of the component manufacturers on this MERIDA CDROM.
Additional information “Before your first ride” with your MERIDA pedelec 1. Have you ridden a pedelec yet? Please note the particular riding characteristics of this revolutionary hybrid drive concept. Set off for your first ride by selecting the lowest level of drive assistance (a)! Slowly approach the potential of your MERIDA pedelec in an area free of traffic. 3. The functions of your MERIDA pedelec are operated with the buttons on the drive HMI (c) or on the command console (d).
H Pulling the brake lever of the rear brake stops the motor. Emergency stop! We recommend that you charge your battery only during the day and only in dry rooms which have a smoke or a fire detector; but not in your bedroom. Place the battery during the charging process on a big, non-inflammable plate made of ceramics or glass (e)! Unplug the battery once it has been charged up. Be aware that the brakes of your MERIDA pedelec are always more effective than the drive.
Before every ride Your MERIDA bike has undergone numerous tests during production and a final check has been carried out by your MERIDA dealer. Nevertheless, be sure to check the following points to exclude any malfunctioning that may be due to the transport of your MERIDA bike or to changes a third person may have performed on your MERIDA bike before delivery: 1. 3. Spin the wheels to check whether the rims are true.
5. Let your MERIDA bike bounce on the ground from a small height. If there is any rattling, see where it comes from. Check the bearings and bolted connections, if necessary. Tighten them slightly, if necessary. 6. In case you have a MERIDA bike with suspension, press down on your MERIDA bike and see whether the spring elements retract and extend as usual (d). For more information see the chapters “Suspension forks” and “Rear shocks” and the instructions of the component manufacturers on this MERIDA CDROM.
Additional information “Before every ride” with your MERIDA pedelec 1. For more information see the system instructions of your drive manufacturer on this MERIDA CD-ROM. 4. Is the battery tight in its holder and the lock properly locked up (d)? Never set off with a loose and unlocked battery.
After an accident 1. Check whether the wheels are still firmly fixed in the drop-outs (e) and whether the rims are still centered with respect to the frame or fork. Spin the wheels and observe the gap either between brake pads and rim sides or between frame and tire.
For more information see the chapter “The gears” and the instructions of the component manufacturers on this MERIDA CD-ROM. Back home you need to check your MERIDA bike thoroughly. Damaged parts must be repaired or replaced. Ask your MERIDA dealer for advice. 4. Make sure the saddle is not twisted by using the top tube or the bottom bracket shell as a reference (a). If necessary, open the clamping, realign the saddle and retighten the clamping.
Additional information “After an accident” with your MERIDA pedelec 1. Do not set off on your MERIDA pedelec when the drive HMI or the display shows a warning. In such a case, contact your MERIDA dealer immediately. Check the rechargeable battery (e+f). If the rechargeable battery is no longer properly in its holder or shows any damage, do not use your MERIDA pedelec any longer, at least not in the assistance mode. Switch off the drive and the rechargeable battery separately, if necessary.
How to use quick-releases and thru axles Do not touch the brake disc directly after having stopped, e.g. after a long down-hill ride, you may burn your fingers! Always let the brake disc cool down before opening the quick-release. G Quick-release Most MERIDA bikes and MERIDA pedelecs are fitted with quick-releases (a) to ensure fast adjustments, assembly and disassembly. Be sure to check whether all quick-releases are tight before you set off on your MERIDA bike.
How to fasten components securely with a quick- release To check whether the lever is securely locked apply pressure to the end of the hand lever and try to turn it while it is closed. If you can turn the lever around, open it and increase the preload. Screw the tightening nut on the opposite side clockwise by half a turn. Close the quick-release lever and check it again for tightness. Open the quick-release. You should now be able to read “Open“ (e) on the lever.
Thru axles After wheel mounting test the brakes in stationary. You should reach the pressure point of the brake before the brake lever reaches the handlebars. In the case of hydraulic brakes pump them, if necessary, until you reach a precise pressure point. Check by compressing the suspension fork repeatedly. G Thru axles (a-d) provide suspension forks and rear shocks with a higher stiffness.
Manitou Hex Lock QR15 (e.g. Manitou Mattoc and Marvel) Marzocchi 20mm Taperwall axle (e.g. Marzocchi 888 CR 180) The Manitou Hex Lock system (e) can be adjusted without tools and locked with a quarter turn after wheel mounting. Mounting wheels If your bike is equipped with a Marzocchi 20mm Taperwall thru-axle system (h), put the front wheel into the fork and mount the rotor in the brake caliper. In contrast to the QR15-axle there is no need to unfold the lever and to unscrew the axle with difficulties.
Dismounting wheels To dismount the wheel release the four bolts which ensure the fixing of the axle to the fork by two to three turns. Do not unscrew the bolts completely. Subsequently, release the counterpart of the axle/bolt cap and remove the axle completely from the hub. i More information are provided at www.marzocchi.com Marzocchi 15mm QR (e.g.
RockShox Maxle 360™ Dismounting wheels If your bike is equipped with a Maxle thru-axle system, open the quick-release lever completely. Mounting wheels If your bike is equipped with a Maxle thru-axle system with quick-release lever, put the front wheel into the fork and mount the rotor in the brake caliper. Bring the front wheel into the right position between the drop-outs and slide the axle with open Maxle quick-release levers from the right side through the drop-out and the hub (e).
As soon as the axle thread engages with the thread of the right fork leg, close the axle by turning it clockwise (a). During the first rotations you should be able to rotate the thru axle nearly without resistance. Tighten the axle a little. Close the E-Thru quick-release lever like a usual quick-release lever (b). Once you have screwed out completely the thru-axle thread from the thread of the lower leg, you can remove the thru axle completely.
Dismounting wheels If your bike is equipped with an SR SUNTOUR Q-LOC-system 15 mm, open the quick-release lever completely. Apply a little pressure on the counter nut and turn the counter nut counterclockwise until the expander releases. Once you have screwed out completely the thru-axle thread from the thread of the lower leg, you can remove the thru axle completely. i Close the E-Thru quick-release lever like a usual quick-release lever (g).
Adjusting the MERIDA bike to the rider Your body height and proportions are decisive for the frame size of your MERIDA bike. Pay particular attention to the fact that there is enough clearance between your crotch and the top tube so that you do not hurt yourself when you have to get off your bike quickly. By choosing a specific type of bike you roughly determine the posture you will be riding in (a+b).
Adjusting the saddle to the correct height The correct saddle height depends on the length of your legs. When pedaling, the ball of your foot should be positioned above the center of the pedal axle. With your feet in this position you should not be able to stretch your legs completely straight at the lowest point, otherwise your pedaling will become awkward (e). Align the saddle with the frame by using the saddle nose and the bottom bracket or top tube as a reference point.
Never apply grease or oil into a seat tube of a frame made of carbon unless an alloy sleeve is inside the frame. If you mount a carbon seat post, do not put any grease on it, even if the frame is made of metal. Once greased, carbon components may never again ensure reliable clamping! Use special carbon assembly paste instead (a). If the seat post does not move easily inside the seat tube or if it cannot be tightened sufficiently, ask your MERIDA dealer for advice.
Adjusting the height of the handlebars The height of the handlebars compared to the saddle and the distance between saddle and handlebars determines how much your upper body will be inclined forward. Lowering the handlebars gives you a streamlined position and brings more weight to bear on the front wheel. However, it also entails an extremely forward leaning posture which is tiring and less comfortable, because it increases the strain on your wrists, arms, back, upper body and neck.
Conventional stems Never exceed the maximum torque value indicated by the manufacturer! You will find the prescribed values in the chapter “Recommended torque settings”, directly on the components and/or in the operating instructions of the component manufacturers on this MERIDA CDROM. Handlebars with conventional stems allow limited vertical adjustment. This is done by moving the stem up or down inside the fork steerer tube. Release the expander bolt by two to three complete turns.
Adjustable stems Stems for threadless systems, the Aheadset®system There are various solutions for adjusting the tilt of the front part of adjustable stems: Some designs use bolts on the sides of the joint (e), others have bolts coming from above or below, and others again are equipped with additional locking mechanisms or adjusting bolts. e Ask your MERIDA dealer to explain you both function and adjustment of your stem or, still better, let him do that work.
If you want to turn the stem around, you have to also release the front bolts securing the handlebars (a). If the stem is fitted with a cap, you can simply take out the handlebars at this point. If it is not fitted with a cap, you have to remove the handlebar fittings. Mount the handlebars and, if necessary, the handlebar fittings, as described in the chapter “Adjusting the tilt of the handlebars and brake levers” and/or in the instructions of the component manufacturers on this MERIDA CD-ROM.
The bolted connections of the seat post have to be tightened to the prescribed torque value. Use a torque wrench and never exceed the maximum torque values! You will find the prescribed values in the chapter “Recommended torque settings”, directly on the components and/or in the operating instructions of the component manufacturers on this MERIDA CD-ROM.
G Poorly tightened or loosening bolts can fail. Risk of an accident! Check the bolts by using a torque wrench once a month according to the values indicated directly on the components and/or in the instructions of the component manufacturers on this MERIDA CD-ROM. Check the strength while you press with your hands alternate at the top and back of the saddle. The saddle may not move (c).
Adjusting the brake lever reach The clamping mechanism or the saddle rails could break and result in an accident and/or injuries to the rider. With most brake systems the distance between the brake levers and the handlebar grips is adjustable. This gives in particular riders with small hands the convenience of bringing the brake levers closer to the handlebars (g). Use a different saddle model or contact your MERIDA dealer.
In the case of hydraulic brakes and disc brakes follow the instructions of the brake manufacturer, which you can find on this MERIDA CD-ROM. If you are in doubt or if you have any questions, contact your MERIDA dealer. You find them directly on the components and/or in the instructions of the component manufacturers on this MERIDA CD-ROM. I Adjusting the tilt of the handlebars and brake levers If the handlebars are not tight with the prescribed torque value, use carbon assembly paste.
Note that the bolted connections of stem, handlebars, bar ends and brakes have to be tightened to their specified torques. Use a torque wrench and never exceed the maximum torque values! You will find the prescribed values in the chapter “Recommended torque settings”, directly on the components and/or in the operating instructions of the component manufacturers on this MERIDA CD-ROM.
Adjusting the saddle height Be sure to also avoid the following, as this would put too much stress on the material resulting in premature wear or failure: - In the case of MERIDA dirt and freeride bikes the saddle height depends on the use. The seating position is not comparable to that of other bikes, as in this case it is all about maximum control and freedom of movement on the bike.
The brake system MERIDA mountain bikes of this type can be worn down after one season only that major and/or load bearing parts must be replaced. Have bikes of these types thoroughly checked by your MERIDA dealer at least every three to four months. G A saddle at low height is recommended in general for steep downhill rides with your MERIDA mountain bike. Long pedaling with low saddle height can result in knee problems.
Wet weather reduces the braking effect and the road grip of the tires. Be aware of longer stopping distances when riding in the rain, reduce your speed and actuate the brakes carefully. There are various types of brake systems that may be subject to the following problems: Rim brakes (a) are liable to overheating as a result of too long braking or brake dragging.
Rim brakes See your MERIDA dealer and ask them to examine the remaining thickness of the rims when you have worn through your second set of brake pads at the latest. He has special measuring devices to determine the remaining thickness of the rims. V-brakes and cantilever brakes Functioning and wear V-brakes (e) and cantilever brakes (f) have two brake arms mounted separately on either side of the rim. When actuating the brake lever, both arms are pressed together by the cable, the pads touching the rim.
Synchronizing and readjusting To readjust the brakes, unscrew the knurled lock ring located at the point where the brake cable enters the brake lever on the handlebars (b). Unscrew the knurled, slotted adjusting bolt by a few turns. This reduces the free travel of the brake lever. Almost all brake designs have a bolt located next to one or both brake calipers for adjusting the spring preload (a). Turn the bolt slowly and watch how the gap changes between brake pads and rim.
The friction generated by braking causes wear to the brake pads as well as to the rims. Frequent rides in the rain and dirt and over hilly terrain can accelerate wear on both braking surfaces. Some rims are provided with wear indicators, e.g. grooves or circular indentations. If the rim is worn down to the point where the grooves or indentations are no longer visible, it needs to be replaced.
Synchronizing and readjusting Disc brakes Hydraulic rim brakes are synchronized together with the alignment of the brake pads. The position of the brake lever where the brake starts to act, also referred to as the pressure point, can be adjusted to the size of the hand as well as to individual convenience at the same time. Also observe in this regard the instructions given in the chapter “Adjusting the brake lever reach“.
Dirty brake pads and rotors can lead to drastically reduced braking force. Therefore, make sure the brake remains free of oil and other fluids, especially when you clean your MERIDA bike or grease the chain. Dirty brake pads cannot be cleaned under any circumstances, they must be replaced! Rotors can be cleaned with special brake cleaners or with warm water and mild soap. Wear and maintenance G Unusual noises (scratching, chafing etc.
Mechanical disc brakes Repeated readjustment at the brake lever makes the arm on the brake caliper change its position. This can make the brake less effective and result in a complete brake failure in an extreme case. Risk of an accident! Functional check The more the brake pads of mechanical disc brakes wear down, the longer is the brake lever travel. Regularly check whether you get a positive braking response before the lever touches the handlebars.
The gears A Derailleur gears The gears (e+f) of your MERIDA bike serve to adjust the gear ratio to the terrain you are riding on and the desired speed. bike. e A low gear (where in the case of derailleur gears the chain runs on the small chainwheel and a large sprocket) allows you to climb steep hills with moderate pedaling force. You must, however, pedal at a faster pace. High gears (large chainwheel, small sprocket) are for riding downhill.
Modern mountain bikes can have up to 33 gears. As there are, however, overlapping ranges, actually 15 to 18 gears are usable. It is not advisable to use gears which involve an extremely oblique run of the chain, as this reduces power transmission efficiency and hastens wear of the chain. An unfavorable run of the chain is when the smallest chainwheel is used with one of the two or three outermost (smallest) sprockets (a) or when the largest chainwheel is used with one of the inmost (largest) sprockets (b).
Checking and readjusting The principle of twist grips is different (h). Turning the right-hand grip towards you makes for a lower gear ratio, while the same movement on the left produces a higher gear – and vice versa. The shifting direction may vary in this case, as well. Always wear straight-cut trousers or use trouser clips or the like. To make sure your trousers do not get caught in the chain or the chainwheels.
Adjusting the rear derailleur Adjusting the limit stops Increase the tension of the Bowden cable by turning the adjustable cable stop at the shifter lever (a) or the adjusting bolt through which it runs into the rear derailleur. To do so, shift to the smallest sprocket and turn the bolts counterclockwise in half turns until the cable is slightly tensioned.
Adjusting the front derailleur If your MERIDA bike has tipped over or the rear derailleur received a blow, the rear derailleur or its mount, also referred to as the derailleur hanger, might be bent. It is advisable to check its range of movement and readjust the limit screws (e), if necessary, after such an incident or after mounting a new rear wheel on your bike. A A Be sure to do a test ride in an unfrequented place after adjusting the gears.
Multi-speed hubs (internal gear hubs) In the case of multi-speed hubs and gearbox shift systems “1” stands for the first, lowest gear. The gears are shifted through one after the other, if possible without turning the pedals, at least, however, at reduced pedal pressure. The highest number stands for the highest gear. Functioning and operation The advantages of multi-speed hubs (a+b) are their enclosed design.
A Adjusting multi-speed hubs Always make sure changing gears makes as little noise as possible and is absolutely jerk free. Make yourself familiar with the operation of your gears in a place free of traffic and practice operating the shifters or the twist grips as well as the brake system, before using your bike on public roads. Shift into the fourth (4th) gear. Look from above at the right-hand side of the hub (e+f). There you can see two yellow markings.
Chain - Care and wear Chain maintenance Regular and correct lubrication of your bike’s chain makes for enjoyable riding and prolongs its service life. It is not the quantity, but the distribution and regular application of lubricant that counts. Clean the dirt and oil off your chain with a slightly oily rag from time to time (a). Special degreasers are not necessary; they even have a damaging effect.
The wheels and the tires The wheel consists of the hub, the spokes and the rim. The tire is mounted onto the rim so that it encases the tube in the case of the most common system, i.e. the clincher or folding tires. There is a rim tape running around the rim well (e) to protect the sensitive tube against the edges of the rim trough, which are often sharp. A After the bedding-in period, check the wheels regularly. It will, however, rarely be necessary to tighten the spokes (f).
Replace tires with a worn tread or with brittle or frayed sides. Dampness and dirt penetrating the tire can cause damage to its inner structure. The tube might burst. Risk of an accident! The tires must be inflated to the proper inflation pressure to provide an optimal compromise between smooth running and riding comfort. Properly inflated tires are also more resistant to punctures. An insufficiently inflated tire can easily get pinched (“snakebite”), when it goes over a sharp kerb.
Valves Rim trueness and spoke tension There are two valve types in general use on mountain and cross bikes: 1. Sclaverand or Presta valve (d): This valve is nowadays used on almost all types of bikes. It is designed to withstand extremely high pressures. 2. Schrader or American valve (e): This is an adapted car tire valve. For the true running of the wheel it is imperative that the tension exerted by the spokes is distributed evenly around the rim. If the tension of a single spoke changes, e.g.
Tire puncture Flat tires are the most common cause of puncture during cycling. However, as long as you have the necessary tools and a spare tube or a repair kit, this need not mean the end of your cycle ride. If your wheels are attached with quick-releases to the frame and the fork, you only need two tire levers and a pump (a). it doesn’t interfere with the removal of the wheel. Open the quick-release of the wheel, as described in the chapter “How to use quick-releases and thru axles”.
Clincher and folding tires In the case of double wall rims the tape must cover the entire rim base, but it should not be so broad as to stand up along the inside edges of the rim trough. Rim tapes for this type of rim should only be made of fabric or durable plastic. If you are in doubt or if you have any questions, contact your MERIDA dealer. Dismounting tires Remove the cap and the fastening nut off the valve and deflate the tire completely (f).
Mounting tires Before fitting the tire completely on the rim check again whether the inner tube lies properly inside the tire and press the last stretch of tire over the edge of the rim using the balls of your thumbs. When mounting a tire make sure that no foreign matter such as dirt or sand gets inside the tire and that you do not damage the inner tube in the process. Slip one bead of the tire onto the rim.
Tubeless tires (UST tires) Improper mounting can lead to malfunctioning or tire damage. Therefore, it is essential to follow the instructions of the component manufacturer on this MERIDA CD-ROM. A Dismounting tires Deflate the tubeless/UST tire completely (h). Press the tire from one side towards the center of the rim, until the tire bead is loose in the rim base. Lever this tire side completely over the rim side or the rim edge and start on the side opposite of the valve.
Check whether the tire is properly seated by inspecting the fine witness line on the tire just above the rim edge. This line should be even to the rim all around the tire. If you have disc brakes, check before mounting the wheel whether the brake pads rest snugly in their seats in the brake caliper body. The gaps between the brake pads and the wheel should be parallel and the wear indicators in their correct position.
Special characteristics of carbon Remount the brake caliper of hydraulic rim brakes immediately and close the quick-release! Make sure that the brake caliper does not touch either the rim or the tire or the spokes when the wheel turns. G G Before setting off again check that the brake surfaces and/or rotors are still free of grease or other lubricants after the wheel mounting.
Do not combine carbon handlebars with bar ends, unless they are specifically approved. Do not shorten carbon handlebars or clamp the brake levers and shifters more in the middle than indicated or needed. Risk of breakage! Carbon components must not be exposed to excessive heat. Therefore, never have a carbon component enameled or powder-coated. The temperatures required for enameling or powder-coating could destroy the component.
Headset Protect the exposed areas of your carbon frame (e.g. the head tube and the underside of the down tube) against rubbing cables or stone chips with special pads (c+d) your MERIDA dealer keeps for sale. I Carbon fiber components are particularly vulnerable to damage caused by excessive clamping force. Carbon assembly paste creates extra friction between two surfaces, allowing the necessary torque value to be reduced by up to 30 %.
Check the headset for play as described above (c). Take care not to tighten the bearing too much, as this could easily destroy it. If you face any problems during the test, contact your MERIDA dealer. G Adjusting the headset requires a certain amount of experience and should therefore be left to your MERIDA dealer. Threadless headsets – Aheadset® This headset system is characterized by the fact that the stem is not in the fork steerer tube but clamps it from outside.
Suspension Spring preload Glossary Suspension forks Bicycle fork (e) absorbing and damping shocks through moving components. The most common among these forks are the telescopic suspension forks. What is designated as stanchion tubes are the thinner tubes press fitted or screwed to the fork crown of a telescopic fork. What is designated as lower leg are the lower tubes in which the stanchion tubes slide in.
Suspension forks Rebound damping (a) In most cases a red adjusting knob. Delays or brakes the rebound. Prevents bike bobbing. Lockout (b) In most cases a lever on the suspension element or the handlebars. A device to block the fork or the rear shock so that the suspension element does not cause bob when riding on tarred roads or smooth surfaces. Not to be used off road. a Most mountain bikes and pedelecs are equipped with suspension forks (d).
Adjusting the spring rate Put on your usual riding clothing (including if necessary a packed rucksack), sit on your bike and bring yourself into the usual riding position. Lean against a fixed object (railings, wall etc.) and make sure you do not fall over. Ask a helper to move the rubber ring or the cable tie downwards against the dust seal at the lower leg (f). To work perfectly, the suspension fork has to be adjusted to the weight of the rider, the sitting posture and the intended use.
In the case of most suspension forks with coil springs a preload can be applied to the springs within tight limits by turning a knob at the top of the fork crown (a). If that is not possible and the desired negative suspension travel (“sag”) cannot be set, the coil springs must be replaced by harder or softer models. The replacement is a job for the MERIDA dealer. When replacing any parts, be sure to only use parts that bear the appropriate mark and, to be on the safe side, original spare parts.
Readjusting the suspension travel A Normally, you cycle with the maximum suspension travel of your suspension fork. This provides maximum cycle fun and utmost control over the mountain bike. When climbing steeper hills the suspension travel can be limited by readjusting the suspension travel; the cockpit of your bike is then a little bit lower. Make use of this lowering device mounted on your fork to sit in a more flat position when climbing hills.
Turn the red adjusting knob in the direction “+“ (a) until you hear a click. Compress the fork once again with the front wheel brake pulled and the remove the weight abruptly once again. You will note that the rear shock extends more slowly. Repeat the compression and the release by continuously turning the rebound damping. You will get a feeling for the working of the rebound damping.
Lockout A too strong damping (rebound damping) of the fork can result in the fact that the fork no longer extends when riding over a quick series of obstacles. Risk of an accident! G Do not turn any screws by using tools in the vague hope of adjusting them somehow (e). You could be loosening the fastening mechanism, thus provoking an accident.
Suspension forks are constantly being sprayed with water and dirt from the front wheel. Clean them with plenty of water after every ride. 3. After washing your bike, spray the stanchion tubes of the suspension fork with a little grease spray (a) or apply a very thin film of hydraulic oil. Compress the fork several times and wipe off excess lubricant with a clean rag before you set off for your next ride. Be sure to use the lubricant recommended by the manufacturer. 4.
Rear shocks What to bear in mind when adjusting the saddle Full suspension MERIDA bikes are not only equipped with a suspension fork (e) but also with movable rear stays (f) which are sprung and damped by a rear shock (g). This feature gives you better control of your MERIDA bike when riding cross-country or on rough road surfaces and ensures more ground contact for the tire. It noticeably reduces the strain on you and your bike caused by the mechanical shocks from the terrain.
In general, cross-country and marathon racers prefer a shorter negative suspension travel (sag), freeriders or downhillers riding often in rough terrain prefer a longer one. In the case of cross-country and marathon bikes the rear shock should yield by 10-20 % of the maximum suspension travel, in the case of all mountain, enduro and freeride bikes by 25-35 %. To measure the travel you can use the rubber ring (a) mainly located on the thinner, plunging tube of the rear shock.
Always make a test ride over terrain with various surfaces after each change to the settings. Check afterwards the position of the rubber ring/cable tie (e+f). Its distance from the wiper is the maximum suspension travel that you have used. If the rubber ring/cable tie has moved by even a few millimeters, the setting of the rear shock is too hard. Reduce the pressure, or, in the case of rear shocks with coil spring, the spring preload. If that brings no improvement, have the springs replaced.
In the case of other models, changing the suspension travel does not result in a modified spring characteristic. The rear shock provides an identical comfort of suspension with a however clearly reduced suspension travel. In the case of full suspension rear frames this is typically done by screwing off segments on which the rear shock is mounted or by loosing or readjusting screws. Retighten the bolts subsequently to the required torque.
Ride over an obstacle (e.g. down a kerb) subsequently and turn the rebound damping in small steps towards the “+” setting. You have found the proper rebound setting when the rear shock does not cycle more than once (e-g). Always check a changed adjustment during a test ride in the terrain. Some rear shocks have a compression damping in addition. The typical compression damping, or on some rear shocks the high-speed compression damping, slows down the compression when riding at high speed over an obstacle.
Maintenance When mounting a new rear tire, make sure there is enough clearance between tire and frame as the rear frame compresses entirely. If necessary, deflate the rear shock completely and press the saddle forcefully downward to check this. This can block the rear wheel. Risk of an accident! G Do not ride your bike, when the rear shock bottoms out. This could damage the rear shock itself as well as the frame.
Suspension elements are of sophisticated design. The maintenance routines and above all the disassembly of the suspension elements are jobs best left to your MERIDA dealer or the rear shock manufacturer’s service center. 5. If your rear shock has steel coils, you should regularly have the coils cleaned and lubricated with a non-corrosive resin-free grease (e). Some rear shock manufacturers supply special greases for fork maintenance. Strictly observe the recommendations of the manufacturers.
Riding a MERIDA pedelec – Special features Your MERIDA pedelec is designed to be used like a conventional bike. The unique riding experience, however, starts when you actuate the drive system (a). At that moment the assistance generated by the 250 W motor (b) increases with its high torque the stronger you pedal. Riding with drive assistance a Set off for your first ride by selecting the lowest level of drive assistance. Gradually get used to the additional power.
Do not give in to the temptation to always ride in a high gear, due to the strong motor. Shift gears frequently (e) in the same way that you are used to doing with a conventional MERIDA bike so as to make your own contribution to your forward progress as efficient as possible. Your cadence should always be in a smooth flow. In other words, you should pedal at more than 60 crank rotations per minute.
Range – Useful information for a long ride How long and how far you can benefit from the auxiliary drive depends on several factors, i.e. the road conditions, the weight of the rider and any additional load, the rider’s pedal force, the degree or mode of assistance, (head)winds, frequent stops, temperature, weather conditions, topography, tire pressure, etc.
Riding a MERIDA speed pedelec – Special features Riding without drive assistance You can also use your MERIDA pedelec without drive assistance, i.e. just like a conventional MERIDA bike. Observe the following points when riding without the rechargeable battery (e): - If you want to ride without drive assistance with mounted battery, you can switch on the drive HMI of your pedelec to benefit from the functions of your cycle computer.
Inform yourself in the country where you use your MERIDA speed pedelec about the regulations of - using cycle lanes and paths within built-up areas, - using lanes that are marked with a road sign allowing access for mopeds, - using your MERIDA speed pedelec on cycle lanes which are allowed for mopeds, - may not ride in the wrong (opposing) direction up one-way roads, even if ordinary cyclists are permitted to do this, - using pedestrian zones, even when they are allowed for bikes, - using bike parking facil
Useful information for proper handling of the rechargeable battery Remove the rechargeable battery (e+f), if you do not use your MERIDA pedelec for a longer period of time (e.g. during the winter season). Store the rechargeable battery in a dry room at temperatures between 5 and 20 degrees Celsius. The state of charge should be 50 to 70 % of the charging capacity. Check the state of charge, if the rechargeable battery is left unused for more than two months, and recharge it in between, if necessary.
h Make sure your rechargeable battery is in sound condition (a). Do not open, disassemble or crush the battery. Risk of explosion! h Make sure your rechargeable battery is not exposed to mechanical impacts. h Keep your battery away from fire and heat. Risk of explosion! Batteries must not be short-circuited. Therefore store them in a safe storage area and make sure the battery is not short-circuited accidentally (e.g. with another battery).
s Do not charge your battery over a long period of time, if you do not need it. u Lithium-ion batteries have no memory effect; they can therefore be charged at any time without affecting battery life. u Also observe the notes on the respective labels on the rechargeable battery (e) or on the charger (f). Lighting system When riding on public roads a properly functioning lighting set is obligatory (see the chapter “Legal requirements for riding on public roads”).
Things worth knowing about your MERIDA bike Clothing Cycling helmets and glasses Cycling helmets (a) are absolutely recommendable. Your MERIDA dealer has a variety of styles and sizes. Verify that the helmet complies with the test standard DIN EN 1078. Cycling helmets are only approved for use during cycling. Observe the manufacturer’s instructions.
The pedals and the shoes Cycling shoes (e) should be made of solid material to provide firm support for your feet. In addition, they should have a stiff sole so that the pedal cannot press through. The sole should not be too wide in the area of the heels, as the rear stays or the crank will otherwise get in the way of your pedaling. This will prevent your feet from assuming a natural position when pedaling and may cause knee pain in the long run.
I Ask your MERIDA dealer for advice about the different shoe and pedal models. Cycling shoes come in various styles for specific uses. I Read the operating instructions of the pedal manufacturer on this MERIDA CD-ROM. Retrofitted accessories, such as mudguards, pannier racks etc. can impair the functioning of your MERIDA bike. Ask your MERIDA dealer for advice before mounting any kind of accessories to your bike.
Puncture kit Mudguards/wheel protections The most important accessories for a successful cycle tour are a tire pump and a small tool kit. The tool kit should include two plastic tire levers, the most commonly used Allen keys, a spare tube, a tire repair kit, your mobile phone, if necessary, and a little cash (e). In this way you will be well prepared in the event of a puncture or some other mishap. If you want to mount mudguards on your MERIDA bike, ask your MERIDA dealer for advice.
Transporting baggage There are various ways of carrying baggage on your MERIDA bike. Your choice will primarily depend on the weight and volume of the baggage and on the bike you want to use. Using a rucksack (a) is a convenient way of transporting baggage on a bike. G Baggage generally changes the riding characteristics of your MERIDA bike and increases your stopping distance! Therefore, practice riding a loaded bike in a place free of traffic.
Taking children with you Child trailers The only possible and legal way of transporting kids by bike is in special child-carrier seats (e) or trailers (f). Contact your MERIDA dealer. If you want to use your MERIDA bike or pedelec to tow a trailer (g), please check whether it is designed accordingly. Have a look at the bike card or ask your MERIDA dealer for advice. Only buy tested child seats, child trailers, and kids’ bike towing devices (e.g.
Transporting the MERIDA bike or pedelec Kids’ bike towing devices/trailer systems If you want to use your MERIDA bike to mount a towing device (a+b), please check whether it is designed for such a device. If in doubt, ask your MERIDA dealer. I G well! Make sure your child wears a helmet even when riding on a coupled or attached bike.
Read the operating instructions of your bike carrier and comply with the maximum load capacity and recommended or prescribed driving speed. If applicable, comply with the required supporting load on the trailer hitch. Most clamps are a potential source of damage to large-diameter frame tubes that are not designed to be fixed in such clamps! Do not use such systems with carbon frames. Make sure to remove all parts of your MERIDA bike (tools, pannier bags (d-f), child seats (g) etc.
By public transport By plane In the cities the regulations for taking MERIDA bikes by public transport differ. There are e.g. some places where you are only allowed for travel with your MERIDA bike during off-peak hours and with an additional bicycle ticket.
What to bear in mind when transporting your MERIDA pedelec S By car MERIDA pedelecs can be transported like conventional bikes outside or inside the car (e). Always make sure the MERIDA pedelec is securely fastened outside or inside the car and check the fastenings regularly. In addition, you should always remove the battery from your MERIDA pedelec (f+g) prior to fastening it outside the car.
By train / By public transport By plane MERIDA pedelecs can be transported in the same way as conventional bikes by public transport. If you intend to take your MERIDA pedelec by plane or to dispatch it by a forwarding agent, you have to observe particular packing and labeling requirements for rechargeable batteries which are considered as hazardous goods. Contact the airline, an expert for hazardous items or the forwarding agent in time.
General notes on care and servicing The intended use of the MERIDA bike includes regular servicing and the replacement of wearing parts in time, e.g. chains, brake pads or Bowden and brake cables (f), and therefore has an influence on the warranty and the guarantee, as well. Maintenance and servicing Your MERIDA dealer will have assembled and adjusted your MERIDA bike ready for use when you come to collect it. Nevertheless, your MERIDA bike needs regular servicing (e).
Cleaning and caring for your MERIDA bike or pedelec Dried sweat, dirt and salt from riding during the winter or in sea air can harm your MERIDA bike. You should therefore make it a habit of cleaning all components at regular intervals (a). Avoid cleaning your bike with a high-pressure cleaner. The high-pressure jet is likely to enter bearings by passing through the seals and dilute the lubricants hereby increasing the friction. This destroys and impairs the functioning of the bearing races in the long term.
S Remove the seat post (h) and let moisture that may have entered dry. Spray a little finely atomized oil into the metal seat tube. However, do not apply oil in a carbon seat tube. Shift the gear to the smallest chainwheel and the smallest sprocket. This relaxes the cables and the springs. Please note that in the case of speed pedelecs only certain components are allowed to be replaced to provide insurance cover.
Servicing MERIDA speed pedelecs – Special features Drive maintenance and care Please note that in the case of MERIDA speed pedelecs only certain components are allowed to be replaced, otherwise there is the risk of loosing the operating license and the insurance cover. Only use spare parts confirmed by experts’ reports on the approval for your MERIDA speed pedelec. As an alternative you may also go through an individual approval process by a technical inspection authority of your country.
Service and maintenance schedule It is advisable to have your MERIDA bike serviced regularly after the bedding-in phase. The schedule given in the table below is a rough guide for cyclists who ride their bike between 1,000 and 2,000 km or 50 to 100 hours of use a year. If you consistently ride more or if you ride a great deal on poor road surfaces, the service intervals will shorten accordingly.

Recommended torque settings All bolted connections of the MERIDA bike components have to be tightened carefully and checked regularly to ensure the safe and reliable operation of the MERIDA bike. This is best done with a torque wrench that disengages at the desired torque value or a click-type torque wrench. Tighten carefully by approaching the prescribed maximum torque value in small steps (0.5 Nm increments) and check in between the proper fit of the component.
