Review: Bike-boosting Copenhagen Wheel finally hits the streets
Yes, its really here.
The US version of the Copenhagen Wheel (which is the one that we got) has a 350-watt motor powered by a 48V/279Wh lithium-ion battery, which takes four hours to charge. That motor kicks in whenever you pedal, adding a proportional amount of electrical assistance – a top motor-assisted speed of 20 mph (32 km/h) is possible, and there is no throttle-only mode. One charge of the battery is good for a range of up to 30 miles (48 km), although that will depend greatly on factors such as the hilliness of the ride.by
