5. Carry out a visual inspection of the brake blocks. The brake blocks must not be worn beyond the wear
indicator.
6. Carry out a visual inspection of the brake position. The brake shoes must have the same distance to the
rim on both sides.
7.8.6 Checking the back-pedal brake
1. Ride at walking pace.
2. Pedal “backwards” against the driving direction.
3. The rear wheel must be sharply braked.
7.9 Inspecting the drive and chain
1. Turn the right-hand pedal arm in an anti-clockwise direction and observe the chainwheels and the
sprocket assembly from above. On bikes with a backpedal brake, ask someone to lift the back of the bike
and turn the right hand crank in the drive direction.
• The chainwheels and sprockets must not have any lateral runout.
• There must not be any foreign matter in any of the components. Remove any such foreign matter if it
is easy to do so.
2. Press the left-hand pedal arm towards the chain run in the position shown.
• You should not feel any bearing play.
• No cracking or grinding noises should be heard.
3. Inspect the chain for damage. The chain must not be damaged at any point, e.g. by bent chain links,
protruding chain link pins, etc. or jammed and immobile chain links.
4. With the bike at standstill, turn the right-hand pedal lever contrary to the drive direction and observe
the chain run at the derailleur rollers of the rear derailleur. The chain must run smoothly over the de-
railleur rollers and must not “jump”. (This test does not apply to bike with backpedal brakes)
7.10 Inspecting the lighting system
WARNING Danger from falls and accidents
Failure of the headlight and rear light can lead to dangerous riding situations in the dark or with poor vis-

• In poor visibility conditions, you should operate your bicycle only when the lights are turned on and
working properly.
1. Turn your lights on. See user information for your lights or ask your dealer.
2. Lift the front wheel if you have dynamo-powered lights.
3. Rotate the front wheel vigorously by hand.
• The headlight and rear light must come on.
• If your bike has a parking light, the headlight and rear light must also light up when the front wheel
stops turning.
4. If you have battery-powered lights either on your bike or as an accessory, check whether these light up
after you have switched them on.
7.11 Inspecting the luggage rack
WARNING Danger from falls and accidents
Loose or hanging parts of the luggage rack can become trapped in the wheels, jamming them and result-
