With its 250W road-legal motor, high-capacity battery and 20-inch fat tyres, it’s equally at home in the city, on countryside trails or packed into the boot of a car for weekend adventures.
Smooth Power Delivery
The 250W brushless rear hub motor provides reliable pedal assistance up to 25km/h, fully compliant with UK and EU regulations. With multiple PAS levels and Shimano gears, it adapts to a variety of terrains, while higher peak output is available for private/off-road use.

Tech You Can Trust
A bright colour LCD display provides real-time ride information including PAS level, speed, battery status and trip data. Integrated LED headlights and rear lights improve visibility and safety when riding in low-light conditions.
Built for Everyday Use
