The G Plus battery base required an added mounting area to the seat tube, therefore the better way to measure the
seat tube is from the base of the saddle clamp (seat post must be inserted at the lowest position) to the centerline
of the crank. When measuring this way, the G Plus Genesis would be considered an 18” frame. Even though
considered an 18” frame, the frame is unique in other areas, allowing for all size riders and adjustable to be similar
to a 23” road bike frame.
The G Plus Genesis’s has a high seat tube angle. With the high angle seat tube, as a tall rider raises their saddle to
accommodate their longer legs, the saddle will pull back offering a longer distance to the steering tube. For fine
detailed adjusting, the narrow seat post saddle clamp allows the saddle to be moved back or forward an additional
7.5mm each way.
c. Recommended sizing
In today’s bicycle industry, the top tube length is actually more important than the seat tube length. With seat posts
now available over 300mm, the seat tube length is no longer the most important number. The distance of the
bottom bracket to the road can also mislead the seat tube length. The top tube length is traditionally the distance
from the center of the seat tube to the center of the steering tube. For purposes of sizing the G Plus Genesis, we
will name the distance of the center of the saddle to the center of the handlebar the steering length (similar to the
top tube length).
You can adjust the steering length of your G Plus Genesis by establishing the saddle position and handlebar height
combined with the adjusting of the stem rise via rotation. The saddle position can be adjusted for height and
distance from the steering tube via the quick release clamp and the saddle clamp. Keep in mind by increasing the
height of the saddle; this will also increase the steering length due to the angle of the seat tube. If you choose to
use your bicycle as a scooter style vehicle only, you should establish saddle height at a lower position to reduce the
center of gravity. Saddle height can be reduced to just above your inseam. Your inseam is the measurement of the
inside of your leg.
d. Control position adjustments
The G Plus Genesis includes a thumb variable throttle with an LED battery indicator on the right side and a 7
Speed twist shifter on the left side of the handlebar. There is also a thumb sliding lever bell on the left side of the
handlebar. The throttle can be adjusted on the handlebar to rotate further up or down (you will need to use the 3mm
hex key included with your G Plus multi-piece tool kit). The shifter can be adjusted on the handlebar to rotate also
(using the multi-tool included with the bicycle). The brake lever assembly and throttle mount together and at a
certain point of rotation, one will not rotate further without the other requiring to be rotated. If the factory settings on
the throttle or shifter are uncomfortable for you or you cannot view the LED battery, you can loosen the throttle
clamp and move it into a preferred position. As stated above, you most likely will have to loosen the brake
assemble to move the throttle to your desired position. Please see section e “Brake lever height adjustments”
following this section to loosen and adjust the brake lever assembly and maintain correct brake lever height
adjustments. To loosen and adjust the throttle, locate the 3mm hex bolt at the front underside of the LED battery
indicator on the throttle. Use your 3mm hex key and insert it into the hex bolt and rotate a minimum of 3 times
counter clockwise. The throttle will now be loose enough to move. Throttle clamp bolts should be tightened to
25 lb*in.
Your G Plus Genesis includes a thumb lever bell for you to use to warn other people around you when
approaching. The thumb lever bell can be moved to a more comfortable position if the factory setting is
unsatisfactory (you will need to use the Philips screw driver included with your G Plus multi-piece tool kit). On the
underside of the bell handlebar clamp there is a small Philips screw. Using the G Plus Philips screw driver, turn the
screw counter clockwise 4 rotations to loosen the clamp enough allowing the bell to me moved. Move the bell to the
desired position and using your G Plus Philips screw driver, tighten the clamp screw by turning clockwise until tight.
e. Brake lever adjustments
The level at which brake lever assemblies are preferred vary from rider to rider. Some riders also have smaller
hands than other riders and need the brake levers’ reach to be closer to the handlebar. The G Plus Genesis
includes Promax top of the line XL-86 brake lever assemblies which can be rotated to a desired height and also the
levers’ reach can be adjusted inwards.
Promax XL-86 brake lever assemblies have the clamp bolt accessible from the top of the bracket (you will need to
use the 4mm hex key included with your G Plus multi-piece tool kit). Using the 4mm hex key, loosen the brake lever
assembly by turning the hex bolt counter clock wise 3 full turns. The lever assembly will now be loose and you can
rotate it up or down to establish the preferred position to apply the brakes while riding. The brake lever assembly on
the right side of the handlebar may require the throttle clamp and shifter clamp to be loosened to allow the brake
lever assembly to rotate. The brake lever assembly, shifter and throttle mount together and at a certain point of
