The Cyrusher Rumble 2.0 is a high-performance fat-tyre electric mountain bike built for riders who want power, endurance, and rugged capability. With a 250W road-legal motor (unlockable for higher output), a massive 52V 20Ah battery and full suspension, it’s designed for commuting, off-road adventures, and long-distance exploration.
Smooth Power Delivery
Equipped with a 250W brushless rear hub motor, the Rumble 2.0 provides smooth and consistent assistance up to 25km/h, fully compliant with UK/EU regulations. Unlocking gives access to higher peak power for private/off-road use, delivering strong torque and confident climbing ability.
Comfort & Control
26” x 4.0” fat tyres offer outstanding grip and stability across sand, snow, gravel, and tarmac. Full suspension—front air-suspension fork and rear shock absorber—ensures a smooth, controlled ride on rough terrain. Hydraulic disc brakes provide responsive stopping power in all conditions.
Smart Battery System
A 52V 20Ah lithium-ion battery powers the Rumble 2.0, delivering up to 100–120km of pedal-assist range depending on terrain and riding style. The battery is removable and lockable, and charging takes around 7–9 hours.
Tech You Can Trust
A colour LCD display shows PAS level, speed, distance, trip data and battery status. Integrated LED headlights and a brake-activated rear light keep you visible and safe when riding at night or in low-light conditions.
Built for Everyday & Adventure Use
With its rugged aluminium alloy frame and heavy-duty build, the Rumble 2.0 supports up to 150kg. Its combination of fat tyres, long-range battery and full suspension makes it versatile enough for city commuting and extreme outdoor rides.
