Hub Motor Electric Bike Reviews

This type of electric bike utilizes a hub motor (or two) that is built into the wheel. It’s the most affordable type of drive system and often works well with throttle operation. There are two types of hub motors: geared and gearless. Gearless tends to weigh more, provides less torque (especially at low speeds), produce some magnetic drag when not engaged, but may offer regenerative braking, and tend to be very durable and quiet. Geared hub motors tend to be compact, lightweight, and affordable, but they produce a bit of whirring noise during operation and may not be as durable over long periods of use. They freewheel efficiently without producing drag, but cannot provide regen braking. Since motor weight is positioned inside the bicycle wheel itself, it increases unsprung weight if the bike has suspension. It also requires custom spokes, wheels, and axles that bite into the frame to provide forward movement. For this reason, they may also require a torque arm to secure the axle against the frame.
