Two elements make up this E-Bike specific measuring element: the sensor itself placed on one of the frame bases and a magnet placed on one of the spokes of the rear wheel. Once these bikes are tuned, they will only have access to a private or specifically dedicated area, such as a mountain bike course in a fenced area for example. This leads to the withdrawal of its approval and therefore to its banning from circulation. But for this E-Bike class, any modification made (later) to the engine or the assistance system is illegal.

They can also circulate on public roads without conditions. Since they must have a motor of 250W maximum, they are legally considered as classic bicycles without a motor.

This device measures the frequency of the circulation of the magnet at the same level as the sensor and transmits it to the controller. Before unrolling the whole tutorial, know that there exists a website seller of tuning kits : Here is how tuning works in practice :Ī sensor is placed on the frame symmetrically to a magnet placed on one of the spokes of the rear wheel.
