The Klever Mobility propulsion
Please note that a high level of support also means a higher
consumption of current and reduces the range of the system
and the battery.
When you ride faster than 55 km/h., the automatic energy
recovery (technical recuperation) is activated. The motor
operates as a generator and re-charges the battery.
In case the technical recuperation has been activated,
you will hear an acoustic signal. During the process of
recuperation the bars on the display representing the
battery state of charge will start to flash and the LED
light on the battery will once flash red, yellow and green
consecutively.
6.1. Sensors and function
The Speed Pedelec is equipped with a torque sensor in the
dropout, and it is electronically controlled. This sensor
accurately measures the change in chain force at every
pedal stroke (left or right) and informs the system about the
force you exert during pedalling. A computer in the control
unit then calculates these values, and manages precisely
the amount of support from the motor, hence generating a
perfect synergy between the cyclist and the X Speed.
During pedalling, the torque and the pedal sensor measure
very sensitively and exactly the rider’s input and enable
the motor controller to operate the additionally support
of the motor tailored to the needs and riding conditions of
the cyclist.
You can also define the amount of motor support by yourself
choosing between the five levels of support (Turbo, High,
Medium, Low, Ultra Low).
This makes the system very efficient and economic, saving
power consumption and maximizing range. The additional
speed sensor sets the power of the electric motor to zero
once you have reached 45 km/h. Above 45 km/h. speed, the
Speed Pedelec works like a conventional bicycle, the only
way to maintain the propulsion of the vehicle is by pedalling
solely.
The electric motor will only activate if you pedal, therefore,
from a standstill, to start, either you have to pedal, or
actuate the Walk/Turbo button. Without pedalling, by
pressing the Walk/turbo button, the electric motor support
will take you to a maximum speed of 18 km/h. The Walk/
Turbo button was designed as an aid when starting uphill
or in case the bike has to be pushed.
