Road Legal (EAPC)
These bikes are built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning they can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h). You can read the official requirements on the UK government website.
Configurable Models
Some bikes are supplied in a restricted, road-legal setup but are capable of higher performance. If modified or used beyond EAPC limits, they may no longer qualify as road legal and could be classified as motor vehicles under UK law. This may require registration, insurance, and a driving licence. For full guidance, please refer to the official UK e-bike rules.
Private Use Only
Certain high-performance models are intended strictly for private land use with the landowner’s permission. These bikes do not meet EAPC standards and cannot be used on public roads, cycle paths, or pavements unless fully registered and insured in accordance with UK law.
