UK-BASED RETAILER
Shop with confidence
We’re a genuine, authorised retailer for selected brands, with our own Nuneaton repairs workshop.
Buying Cyrusher online?
As with a car, ask where you can take your ride if it needs a repair.
Be cautious if a seller can’t give you a local workshop address, especially if they ship from overseas or dropship.
Check with the brand that the seller is authorised and ask who handles warranty repairs.

Description
Smooth Power Delivery
Equipped with a 250W brushless rear hub motor, the Asuka delivers smooth pedal assist up to 25 km/h, with unlocking options available for private terrain riding. Multiple pedal-assist levels and Shimano gearing offer flexibility across diverse riding conditions.
Comfort & Control
The 27.5-inch wheels combined with knobby mountain tyres provide excellent traction and stability on various surfaces. A front suspension fork softens trail bumps, while powerful mechanical disc brakes front and rear ensure confident stopping power in all conditions.
Smart Battery System
A 48 V 17.5 Ah lithium-ion battery gives the Asuka up to 100 km of riding range per charge, ideal for long rides and weekend adventures. The battery is fully removable and lockable for easy, secure charging.
Tech You Can Trust
An easy-to-read LCD display shows essential ride stats—speed, PAS level, battery life, and trip distance. Integrated front and rear LED lights increase visibility and safety on dawn, dusk, or night rides.
Built for Everyday & Trail Use
The sturdy aluminium frame, strong load capacity, and all-terrain capabilities make the Asuka a reliable companion for both off-road exploration and urban commuting. Its balance of power, comfort, and endurance makes it a versatile choice for any rider.
