Throttle and public-road use in Great Britain
A 250W label or 25km/h setting alone does not establish EAPC compliance. The complete cycle must have usable pedals, no more than 250W maximum continuous rated motor power, an assistance cut-off at 15.5mph, and the required markings and safety equipment. Walk assist limited to 3.7mph (about 6km/h) is outside the throttle type-approval requirement. A twist-and-go cycle introduced after 1 January 2016 that can propel itself without pedalling beyond walk-assist speed requires type approval or individual approval, even if it meets the EAPC power and speed limits. An approved twist-and-go EAPC can still be treated as a pedal cycle; a throttle does not automatically make every bike unlawful.
Using pedal assist, avoiding the throttle or choosing a lower display setting does not establish compliance. Department for Transport guidance also treats cycles with a selectable mode capable of motor propulsion above 15.5mph as motor vehicles. Where the supplied configuration or required approval has not been verified, do not use the bike on public roads or cycle paths as an ordinary EAPC. Use only on suitable private land with permission unless the applicable road-use requirements are met. Read the official EAPC and throttle guidance.
