Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the potential merits of bringing forward legislative proposals to ban the sale of SpeedBox devices in the interests of public safety.

The Department is aware of devices such as SpeedBox which modify the performance of an electrically-assisted pedal cycle but no assessment has been made.

Once an electrically-assisted pedal cycle is modified such that it no longer complies with the speed or power limits laid down in regulation, it is considered to be a motor vehicle (most likely a moped or motorcycle). If the vehicle were to be used on public roads then it and the rider are required to comply with the laws appropriate to those vehicle categories. Enforcement of the law is a matter for the police.
