The Cyrusher Flex is a folding fat-tyre electric mountain bike that combines versatility with power. With its 250W road-legal motor, full suspension system and robust 48V 15Ah battery, it’s designed for commuting, trail riding and off-road exploration while still remaining compliant for UK and EU use.
Smooth Power Delivery
The 250W brushless rear hub motor provides consistent pedal assistance up to 25km/h, with higher peak output available for private/off-road use. Multiple PAS levels and Shimano gears ensure a smooth and adaptable ride across all terrains.
Comfort & Control
26” x 4.0” fat tyres deliver exceptional grip and stability whether on city streets, gravel paths or sand. The full suspension system—front suspension fork and rear shock—absorbs bumps for a smooth ride, while hydraulic disc brakes provide confident stopping power in all conditions.
Smart Battery System
The Flex is powered by a 48V 15Ah lithium-ion battery, removable and lockable for convenience. It offers up to 80–100km of pedal-assist range per charge, with a charging time of around 6–8 hours.
Tech You Can Trust
A colour LCD display provides real-time ride data including PAS level, speed, battery life, and distance. Integrated LED front and rear lights improve visibility and safety in low-light conditions.
Built for Everyday Use
With its foldable aluminium frame, the Flex combines portability with strength, supporting riders up to 150kg. Its design makes it practical for commuting, storing in compact spaces, or transporting in a car, while still delivering mountain bike performance.
