The Cyrusher Quest is a premium folding fat-tyre electric bike designed for versatility, portability and all-terrain performance. 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.
Comfort & Control
20” x 4.0” fat tyres deliver excellent grip and cushioning on tarmac, gravel, sand and snow. A front suspension fork and rear spring shock provide extra comfort, while hydraulic disc brakes ensure powerful and reliable stopping performance.
Smart Battery System
The Quest is powered by a 48V 20Ah lithium-ion battery, removable and lockable for convenience. Offering up to 100–120km of pedal-assist range, it’s built for long commutes or adventurous weekend rides. Charging takes approximately 7–9 hours.
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
With its foldable aluminium frame, the Cyrusher Quest is easy to transport and store while still supporting riders up to 150kg. Its combination of compact design, long-range battery and rugged tyres makes it a practical and versatile e-bike for both commuting and exploring.
