Cyrusher Asuka Key Features
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.
The Cyrusher Asuka Electric Bike 250W 48V 17.5Ah is a trekking-style step-through that focuses on efficiency and range. It pairs everyday practicality with a bigger-than-average battery, making it ideal for riders who commute far or ride in colder, battery-draining weather.
48V 17.5Ah Battery for 50+ Mile Real-World Range
Your Cyrusher Asuka Electric Bike 250W 48V 17.5Ah stock uses a 48V 17.5Ah battery rated for 50+ miles of range in favourable conditions. That extra buffer is perfect for winter commuting, hilly routes or riders who don’t want to live at the charger.
700C Trekking Wheels, Air Fork and Hydraulic Disc Brakes
Large 700C wheels with relatively fast tyres, an air-suspension fork and hydraulic disc brakes make the Cyrusher Asuka Electric Bike 250W 48V 17.5Ah a seriously capable commuter. It rolls quickly on tarmac yet has enough comfort and control for broken surfaces and towpaths.
I use it for a mix of roads and rougher paths and it handles both brilliantly. Comfortable, capable and feels premium. Five stars from me.

Fast-feeling, stable and fun
The Asuka has a really confidence-inspiring ride. It feels stable, responsive and comfortable, and the assist makes hills far less of a chore. Absolutely loving it.
