22 Lighting system
In some EU countries, only lighting systems that are
prescribed by national legislation (the Road Traffic Li-
censing Regulations (StVZO) in Germany for example)
and have been approved for use may be installed on
bikes. If in doubt, ask your specialist cycle shop.
22.1 Specifications for lighting system
• At a distance of five metres, the cone of light
thrown by the front light must be at half the height
of its exit point. The centre of the cone of light
determines its height.
e. g. 1 m
Aligning the front light
• The cone of light thrown by the front light must
only light the road for ten metres at the most. The
centre of the cone of light determines its distance.
22.2 Special regulations for road bikes
• You can fit battery-operated front lights and rear
lights to sports bikes with a maximum weight
of 11 kg (road bike). Please familiarise yourself
with the applicable regulations and, if applica-
ble, have the bike refitted.
• Always carry these with you.
• Dynamo-operated lighting systems must be used
with bikes that weight more than 11 kg. The light-
ing system must come with an official test mark.
Please familiarise yourself with the applicable
regulations and, if applicable, have the bike refit-
ted.

22.3 Generator / dynamo
The dynamo produces the energy required to operate the
front and rear lights. There are different types of dynamos.
22.3.1 Sidewall dynamo
Sidewall dynamo
The dynamo must be positioned so its longitudinal axis
is perpendicular to the wheel axle. The roller must be in
contact with the designated traction surface on the tyre
across its entire width.
Only switch the dynamo on and off when the bike is
stationary as otherwise you could put yourself and
other road users in danger. The sidewall dynamo is
less effective in wet conditions. Provide additional
lighting if necessary.
22.3.1.1 Switching the sidewall dynamo on and off
› Switch the dynamo on/off via the pushbutton or
the lever. The traction roller is now on the tyre
sidewall.
› To switch the dynamo off, pull it away from the tyre
and guide it into its starting position. The dynamo
engages in the starting position.
