Klever’s E-bike drive train
Klever’s E-bike drive train
5.1. Sensors and their function
This Klever 45 km/h E-bike is equipped with a torque sensor in
the frame’s rear dropout. In conjunction with the pedal sensor,
this torque sensor precisely monitors the cycling effort of the
cyclist. The motor controller then calculates the sensor values
and manages precisely the amount of electric support from the
motor. Hence generating a perfect synergy between cyclist and
E-bike.
In addition, you can define the amount of motor support
by yourself as well, choosing between ascending levels of
support (N, ECO, TOUR, MAX, TURBO). This makes the system
very efficient and economic, saving power consumption and
maximising range.
The additional speed sensor sets the power of the electric motor
to zero once you have reached a speed of 45 km/h or more. Above
45 km/h this E-bike functions like a conventional bicycle, the
only way to maintain the propulsion of the vehicle is by pedalling
solely.
The electric motor support only kicks in under the condition that
you actively pedal. Therefore, from a standstill to get started
either you have to pedal or you have to actuate the
á
(TURBO)
button on the display. From standstill without pedalling the
motor will take you to a maximum speed of 4 km/h. Convenient
when starting uphill. The
á
(TURBO) button can also be used in
case the speed E-bike has to be pushed while walking alongside
your bike.
5.2 Levels of electric motor support
The BIACTRON-system offers five levels of electric motor
support:
• N
• ECO
• TOUR
• MAX
• TURBO
Depending on topography, weather conditions and your
personal preferences, you can choose the motor support using
↑ (Up arrow) and ↓ (Down arrow) button and the
á
(TURBO)
button.
System level
Amount of support
Situation (recommended)
N
No support, electric system active
Downhill
ECO
Low support
Flat roads
TOUR
Medium support
Slight hills / headwind
MAX
Strongest support
Steep hills / fierce headwinds
á
(TURBO) (MAX) while
pedalling ≤ 45 km/h.
Strongest support
Steep ramps / violent gusts
á
(TURBO) (MAX) without
pedalling ≤ 4 km/h.
Strongest support
Starting from standstill
á
TURBO) (ECO) walking
with your E-bike ≤ 4 km/h.
Walk-assist, low support
Walking with your E-bike or
pushing it uphill
Please note! In case you actuate the
á
(TURBO) button,
there are three scenarios:
1. You walk alongside the E-bike and/or you push it out of
your garage. While pushing the
á
(TURBO) button you
will activate the Walk-assist mode and you will trigger a
moderate electric motor support up to 4 km/h. In this way
you can walk with your vehicle comfortably and easily.
2. You are sitting on your E-bike and intend to start from
standstill on a ramp without pedalling. Push the
á
(TURBO) button and you will get the strongest support
up to 4 km/h.
3. You are sitting on your E-bike. You are pedalling with
for instance TOUR support and you need the strongest
support momentarily. Push the
á
(TURBO) button
while pedalling and you will trigger the strongest
support regardless your speed (from 0 to 45 km/h).
