Our take on the Electric Bicycle Bike Conversion Kits E-Bike Brush Motor w/ Freewheel 24V 250W

This is a friction-drive conversion kit that mounts a 250W 24V brushed motor and sprocket onto the spokes of an existing bike wheel. The freewheel lets the wheel spin without turning the motor, so pedaling feels close to a normal bike. It suits riders who want a cheap, simple way to add light electric assist to a common bike and who already own a 24V battery and charger, since neither is included. Against mid-drive and hub-motor kits it is far less refined: brushed motors are noisier and less efficient, and the spoke-mounted drive wears tires and rims. Ratings are middling, with buyers citing weak assist and fiddly setup.

About the Electric Bicycle Bike Conversion Kits E-Bike Brush Motor w/ Freewheel 24V 250W

This is an electric conversion kit for a common bicycle. It adds a 250W, 24V brush motor with a freewheel. The kit mounts the sprocket on the wheel spokes, so it fits most bicycle wheels.

Because the motor uses a freewheel, it does not turn when the wheel rotates. The bike rides like a normal bicycle, which reduces resistance. The kit is for bikes with a hub diameter of less than 36mm. A battery and charger are not included.

Questions and answers

What is included in the kit?
The motor with freewheel, chain, sprocket and components, controller, mounting plate and bolts, and a twist throttle with battery indicator and key switch. No battery or charger is included.
What battery does it need?
It runs on 24V and draws up to 250W, so you need a 24V battery sized for that current plus a matching charger. Neither comes in the box.
Will it fit my bike?
It mounts on the spokes and is meant for bikes with a hub diameter under 36mm. Check your hub before buying.
How does the freewheel help?
When the wheel turns without power, the motor does not spin with it, so pedaling resistance stays close to a normal bike.
Is it good for hills?
No. At 250W with a friction drive, it gives light assist on flats and struggles on steep or long climbs.
