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.
