5. Klever’s proprietary electric
propulsion – the BIACTRON
system
You have purchased a 45 km/h E-bike that helps improve
your day-to-day mobility with its electric propulsion. Slopes
can be better managed and wind resistance can be better
overcome.
Klever’s electric BIACTRON system consists of the following
components (image 5.1):
• Rechargeable battery
• Motor
• Control unit / Display
• Motor controller
• Torque sensor
• Pedal Sensor
• Charger (image 5.2)

Powerful system benefi ts
The brushless Klever BIACTRON rear wheel motor comes with
3 powerful advantages:
1. Contrary to centre motor drive trains, with a motor around
the bottom bracket, the direct drive rear wheel motor is
whisper-quiet.
2. The motor in the rear wheel is at the end of the drive train.
For this reason, the electric motor support has no negative
impact on the shifting performance and the wear of the
drive train. By contrast, in E-bikes with a centre motor,
the joined forces and torque of both c motor go
through all components of the drive train. Consequently,
shifting gears goes less smoothly and the wear of drive
train components such as chain, chainwheel, sprockets and
derailleurs goes twice as rapidly.
3. Last but not least, with the rear wheel motor the drive train
has no effi
ciency loss. Motor power and motor torque go
instantly from the tyre to the road surface without any
drive train losses.
Once you turn on the system and you start pedalling, the
motor will support you as long as you continue to pedal, up
to a maximum speed of 45 km/h.
The fi ve levels of motor support of the BIACTRON system can
be selected according to the external circumstances (e.g.,
climbing uphill or riding with headwind) or to your personal
preferences. Please note that a higher level of motor support
consequently means a higher battery consumption. And
reduces the range of the system and battery.
In case you ride faster than 55 km/h (e.g., downhill),
automatically the recuperation of pedal energy (i.e.,
technical regeneration) will be activated. In that case the
motor operates as a generator and partly re-charges the
battery. The recuperation of pedal energy and battery
capacity = REGENERATION will be explained in section 5.3.
Recuperation of battery capacity.
