E-bikes generally combine both pedal-assist sensors as well as a throttle. Some electric bikes have an electric motor that operates on a power-on-demand basis only. In this case, the electric motor is engaged and operated manually using a throttle, which is usually on the handgrip just like the ones on a motorbike or scooter.

A major disadvantage of modern e-bike systems is that they subject the complex transmission components to increased forces. Gearshift comfort and durability of the drive both suffer as a result. The ideal sequence is for the propulsive effort of the rider first to be transmitted through the central Pinion gearbox and then boosted as required by an electric motor. This means the gearbox components are not exposed to additional forces and have a consistent level of precision. This arrangement also retains the low wear on sprockets, chains and toothed belts that is a typical feature of Pinion.
