THE SPARC SYSTEM
WHAT IS SPARC 16V
No matter whether you encounter
headwinds, rain or hills, with Sparc
as your backup you will always have
the upper hand. Sparc, the new light
electric drive with TwinDrive, gives
you that extra boost whenever you
need it.
Sparc was designed and built to
make life easier and more pleasant
for cyclists. Sparc is a solution that
does not change the character of
the bicycle – its light weight,
features, simple maintenance and
comfort ideally complement modern
lifestyles. Its user-friendliness and
superior help function make Sparc
the No. 1 product on the market.
OPERATING PRINCIPLE
Sparc allows cyclists to choose
between two supplementary drive
options. By simply pressing a button
on the control unit mounted on the
handlebars, you can toggle between
the fast SPEED mode and the ECON
mode, which offers increased range.
RANGE
Depending on the mode selected,
Sparc allows a range of action of
25 – 40 km (15 – 25 miles). This means
increased mobility with little effort.
The range achieved by a single
battery charge depends on various
factors. These include drive mode,
the condition of the battery, the road
conditions and particularly the
cyclist’s own effort.

OPERATION
The bicycle can be ridden with or
without the help of the electric
drive. Riding without the help of your
Sparc is like riding any ordinary bike
and requires no extra effort.
When the system is switched on,
you start off as usual. The electric
drive actively supports you whilst
you pedal.
» ECON mode works up to a speed of
approx. 20 km/h (US version 16 mph).
» SPEED mode works up to a speed of
approx. 25 km/h (US version 20 mph).
Once these speeds are reached, the
electric drive switches off and you
continue under your own muscle
power. Reducing speed causes the
system to come on again.
Please charge the battery
before your first trip.
Set the mode required, ECON
or SPEED. The system only
becomes active once the bicycle
moves.
In SPEED mode the red light
gleams.
The condition of the battery is
indicated by 3 green lights.

OPERATION
When only 1 green light gleams, the
battery needs to be recharged.
STANDBY MODE
Your Sparc system has an energy
saving feature.
Approximately 1 minute after you
stop using the system it will auto-
matically switch off and the lights
on the control unit will go out.
When you continue, the electronic
system will automatically come on
again.
5-GEARSHIFTING
A 5-gear hub shift is integra-
ted into the Sparc system. You shift
gears by turning the right twist-grip
on the handlebars through positions
1 to 5.
» Whilst shifting gear continue
pedalling without exerting force.
» If the desired gear does not
engage immediately, briefly stop
pedalling.
» When approaching inclines shift
down in good time.
» You can also shift gears when the
bike has stopped.

Your Sparc bicycle is not for
children!
» Only switch on the Sparc system
when you want to travel on your
bicycle.
» Always switch off the Sparc
system before you stand your
bicycle upside down or hang it up,
also before you carry out cleaning
or maintenance work.
