What are pedal-assist electric bicycles?
Pedal-assist electric bicycles are lightweight vehicles that require the use of both manual pedaling and electric motor power in order to achieve reasonable distance of travel. The majority these employ 180W motors and may use NiMH, Lithium Ion, or sealed lead acid batteries. They do not have the load capacity of large frame e-bikes. Pedal-assist electric bicycles are the most popular in Europe because of restrictions on motor power (<=250W) and travel speed (12 mph maximum).
