107. Electric bicycle
An electric bicycle, or e-bike, is a bicycle equipped with an electric motor that assists the rider while travelling. Most electric bicycles use pedal assistance, meaning that the motor provides additional power while the rider pedals.
The legal classification of an electric bicycle depends on factors such as the motor power, maximum assistance speed and whether the motor can propel the bicycle without pedalling. Faster or more powerful electric bicycles may be classified as mopeds or another type of motor vehicle and can therefore be subject to different licence, helmet, registration and insurance requirements.

Can a high-powered electrically driven bicycle always use British cycle paths?
No. It must meet the rules for an electrically assisted pedal cycle to be treated as a bicycle. Machines outside those criteria may be classed as motor vehicles with different approval, licensing and road-use requirements.
