For the hub dynamo light system and battery powered lighting
systems on pedelecs there is an integrated switch at the front
light to turn the lights on and off.
Hub dynamo
The lighting system with a hub dynamo is
switched on electrically.You will find a switch
on the back of the light with labelled switch
positions. With the switch you can turn the
lighting system on and off and to different
sensor modes. In the sensor positions a twi-
light sensor in the lamp turns the lighting
system on and off or changes between day-
time riding light and standard light automati-
cally depending on the brightness of the envi-
ronment.
The SON hub dynamo is highly efficient and
works silently. When the dynamo is turned off
it has a very low turning resistance. Although
you can feel the single poles of the used per-
manent magnets very distinctly when turning
it by hand the real rolling resistance is minute.
(The loss is below 1 W at 15 km/h / 9,5 mph.)
Lighting system battery
The optional lighting system for bicycles with
the electric assist systems is powered by the
propulsion system’s battery.
To switch the light on and off, use the switch
on the back side of the front light.
The pedelec battery will still provide power
for the lights even though the electrical assis-
tance has been switched off by the battery
management system due to low battery. The
display will still be active for a longer time,
too.
However, you should connect the battery to a
charger soon to avoid exhaustive discharging.
Please pay attention to the electric assist
system manufacturer's manual.
Danger!
Don't try to switch the light
on or off while riding. Stop and get off the
bicycle! There is a serious danger to fall
over or injuring your hands!
