There are currently two types of electric bike available, pedelec and e-bikes.
We use pedelec electric bicycles, an acronym of pedal electric cycle. As the name suggests, a motor responds to the pedalling motion but stops when the rider stops pedalling. In other words, pedalling is assisted by a motor. The amount of additional power the motor provides is dependent on the pedalling force of the driver as measured by a sensor. This system is similar to power steering in cars.
Unlike the pedelec, an e-bike is an electric bike that can move forward without the rider pedalling. Speed adjusted using either a button or a throttle grip. The force exercised by the driver and the power delivered by the electric motor have no influence on each other’s performance. This allows the throttle and pedals to be used simultaneously, something that is not possible with a pedelec. A similar system is also used in mopeds.
