In some EU countries, only lighting systems that are
prescribed by national legislation (the Road Trac 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.

with the applicable regulations and, if applica-
ble, have the bike retted.
•Always carry these with you.
•Dynamo-operated lighting systems must be used
with bikes that weight more than 11 kg. The light-

Please familiarise yourself with the applicable
regulations and, if applicable, have the bike ret-

22.3 Generator / dynamo
The dynamo produces the energy required to operate the
ont and rear lights. There are dierent 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 o when the bike is
stationary as otherwise you could put yourself and
other road users in danger. The sidewall dynamo is
less eective in wet conditions. Provide additional
lighting if necessary.
22.3.1.1 Switching the sidewall dynamo on and o
Switch the dynamo on/o via the pushbutton or
the lever. The traction roller is now on the tyre
sidewall.
To switch the dynamo o, pull it away om the tyre
and guide it into its starting position. The dynamo
engages in the starting position.
