Custom Ebikes Online – INFORMATION

General Information

E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.

Despite these legal complications, the classification of e-bikes is mainly decided by whether the e-bike’s motor assists the rider using a pedal-assist system or by a power-on-demand one.

Definitions of these are as follows:

With pedal-assist the electric motor is regulated by pedalling. The pedal-assist augments the efforts of the rider when they are pedalling. These e-bikes – called pedelecs – have a sensor to detect the pedalling speed, the pedalling force, or both. Brake activation is sensed to disable the motor as well.

With power-on-demand the motor is activated by a throttle, usually handlebar-mounted just like on most motorcycles or scooters.

Therefore, very broadly, e-bikes can be classed as follows


  • Pedal-assist only

  • Motor assists only up to 25 kph

  • Motor power up to 250 watt

  • Often legally classed as bicycles


  • Have pedal-assist only

  • Motor power can be greater than 250 watts

  • Attain a higher speed (e.g., 45 km/h)

  • Legally classed as a moped or motorcycle


  • Power-on-demand and pedal-assist

  • Can be more powerful

  • Legally classed as mopeds or motorcycles
