See UK LegislationEffortless travel for daily commutes and long tours
The Cyrusher Asuka is built for riders who want a dependable, comfortable e-bike for everyday journeys and extended adventures. With a 250W motor, 75-mile range, and a smooth step-thru frame, it makes city travel and country touring feel effortless. Whether you’re commuting to work or exploring UK bike paths, this bike delivers reliable performance and lasting comfort.
Road-legal power that responds to your effort
The Asuka’s 250W Bafang brushless rear hub motor provides smooth, efficient assistance up to 15.5 mph, keeping you within UK regulations. Its torque sensor reads your pedalling and adjusts power instantly, so acceleration feels natural and controlled. You’ll climb hills and cover miles with less fatigue, while still enjoying a genuine cycling feel.
Long-range battery for all-day riding
A 36V 14Ah Samsung battery gives the Asuka up to 75 miles on a single charge, so you can commute all week or enjoy a full day of touring without range anxiety. Recharging takes just 5–6 hours, and the battery is rated for 800 charge cycles. The battery is neatly integrated into the frame, protecting it from the elements and keeping the bike looking sleek.
Comfortable geometry and smooth ride quality
The Asuka’s step-thru aluminium frame and upright riding position reduce strain on your back and shoulders, making it ideal for riders from 5’7” to 6’6”. A breathable ergonomic saddle and 700C x 45C tyres soak up bumps on UK roads and gravel paths. The air suspension fork adds extra cushioning, so you arrive fresh even after long miles.
Confident stopping power in all weather
Shimano MT200 hydraulic disc brakes with 160mm rotors deliver strong, reliable braking in wet or dry conditions. Whether you’re descending a steep hill or stopping suddenly in traffic, you’ll have precise control. The brakes require less hand effort than mechanical discs, reducing fatigue on long rides.
Clear display and intuitive controls
The DZ45 colour display shows your speed, distance, and battery level at a glance, even in bright sunlight. It’s embedded in the handlebar for a clean look and easy reach. The simple button pad lets you switch assist levels without taking your eyes off the road.
Built for everyday practicality
The Asuka comes fully equipped with front and rear mudguards, a sturdy rear rack, and integrated lights, so you’re ready for commuting or shopping from day one. The 10-speed Shimano drivetrain gives you a wide gear range for hills and flats, while the 350 lb payload capacity means you can carry heavy loads. With three colour options—black, blue, and orange—you can choose a look that suits your style.
