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.

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.
