About the Temper Front Hub E-Bike Conversion Kit
Turn your favorite bike into a capable, lightweight electric bicycle in under an hour. The Temper front hub e-bike kit replaces your front wheel with a 350W hub motor and adds our 36V 10Ah (360 Wh) battery to your frame using standard water bottle mounts — no complicated wiring, no permanent modifications.
We believe converting a bike you already love beats buying a heavy, mass-production e-bike.
Keep your bike's fit, geometry, and natural ride feel while adding smooth, responsive electric assist. The Temper kit adds roughly 10 lbs (often less if you're swapping out an older wheel), giving you a lightweight e-bike that actually fits you and handles the way you expect.
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.
