Most bikes with open‑slotted dropouts and quick‑release wheels will work. Check dropout width and make sure your frame has space for the battery.
What are dropouts and how do I measure them?
Dropouts are the slots where your wheel axle sits. Measure the inside width — usually 135 mm for most quick‑release bikes. Match this to the option shown on the product page.

HOW DOES WARRANTY WORK?
Warranty coverage applies only if the product has been professionally installed by a qualified e-bike technician or licensed auto electrician. Proof of professional installation, such as a technician’s invoice or service receipt, will be required to make a warranty claim. Damage caused by incorrect installation, wiring, or modification voids the warranty.
How fast will my e‑bike go?
Check the product page for your kit’s top speed. Actual speed can vary with rider weight, terrain, and battery choice.
