About the Temper Rear Hub E-Bike Conversion Kit
Upgrade your bike with a rear hub e-bike conversion kit designed for smooth, natural power delivery.
The Temper Rear Hub Kit replaces your rear wheel with a 350W hub motor and integrated pedal assist sensor — the same configuration used on most production e-bikes — for a familiar, balanced riding experience.
Paired with our 36V 10Ah (360Wh) battery, which mounts cleanly to standard water bottle bosses, this kit delivers reliable electric assist without compromising your bike's look or feel.
Available in all standard wheel sizes, in polished silver or matte black. If you want to use your own rim, contact us for a kit without the wheel build.

So, Why Choose a Rear Hub E-Bike Kit?
Rear hub motors provide a more intuitive, "push-from-behind" feel — similar to factory-built e-bikes — making them a popular choice for riders who want seamless assist.
- Natural, balanced power delivery
- Ideal for commuting, hills, and longer rides
- Maintains your bike's original fit and geometry
- Sustainable alternative to buying a new mass-market e-bike
- Adds electric assist without bulky frame changes
By converting your existing bike, you extend its lifespan and reduce waste — while avoiding the cost and hassle of a full e-bike replacement.
