How far can the Cyrusher Asuka go on a full charge?

Cyrusher advertises up to 75 miles (120 km) from the 36V 14Ah Samsung battery. Expect less in cold weather, on hills, with higher assist levels or heavier loads.

Can I remove the Asuka battery and charge it indoors?

Yes. The 36V 14Ah battery is removable, so it can be charged on or off the bike.A full charge typically takes around 5–6 hours with the supplied 36V 3A charger.

Is the Cyrusher Asuka good for hills and long commutes?

Yes. Its 250W Bafang hub motor, torque sensor and Shimano 10-speed gearing suit longer road, cycle-path and light-gravel rides. It is a trekking bike rather than a rough-trail mountain bike.

What rider size is the Cyrusher Asuka best for?

Cyrusher recommends riders around 170–200 cm (5'7"–6'6").The payload rating is up to 350 lb (about 150 kg), and the step-through frame makes mounting and dismounting easier.

Is the Cyrusher Asuka Electric Bike easy to assemble?

The Cyrusher Asuka Electric Bike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.

Is the Cyrusher Asuka Electric Bike water resistant?

The Cyrusher Asuka Electric Bike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.
