22.3.2 Hub dynamo
The hub dynamo is inside the hub of the front wheel. The
hub dynamo is highly efficient, and the wear is extremely
low.
Hub dynamo
There is a switch or a sensor on the back of the front light
on some bikes with a hub dynamo. The sensor switches
the light on automatically in the twilight or when passing
through a tunnel. Other models have a switch on the han-
dlebar that switches the lighting on and off.
If you want to remove the front wheel, you first need
to remove the connecting terminal for the light cable.
When you put the front wheel back on, turn it so that
the connecting terminal for the light cable is on the
right-hand side (facing in the direction of travel). If
the connecting terminal is on the left, the dynamo will
not be able to turn properly or the lighting system
may stop working. Ensure correct polarity of the con-
nections.
22.4 Failure of the lighting system
If the lighting system fails or develops a fault when
riding in the dark this could cause a serious accident.
Have the fault repaired at a professional bike work-
shop before you continue your journey.
Extremely powerful (rechargeable) battery-operated bicy-
cle and outdoor lights are available from some retail out-
lets. With some exceptions, use of these lights on public
roads is not permitted.
