Description

Emoko C91 Electric Bike is a 20-inch fat tyre e-bike with a 48V 20Ah battery, 1000W motor, dual suspension and disc brakes.

Emoko’s current UK specification lists a 1000W rated motor, 20Ah battery, a configured 25 km/h (15.5 mph) speed and approximately 60–65 km (37–40 miles) assisted range depending on the section of the manufacturer page.

UK road-use note: because the motor is rated above 250W, the C91 does not qualify as a standard EAPC and should not be treated as a normal road-legal e-bike without the relevant motor-vehicle approvals.
