22.3.2 Hub dynamo
The hub dynamo is inside the hub of the ont wheel. The
hub dynamo is highly ecient, and the wear is extremely
low.
Hub dynamo
There is a switch or a sensor on the back of the ont 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 o.
If you want to remove the ont wheel, you rst need
to remove the connecting terminal for the light cable.
When you put the ont 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 le, 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 powerl (rechargeable) battery-operated bicy-
cle and outdoor lights are available om some retail out-
lets. With some exceptions, use of these lights on public
roads is not permitted.
