1. Will this kit fit my bike?
Yes – if your bike has open‑slotted dropouts and quick release. Make sure to choose the correct dropout size in the product options.
2. What are dropouts and how do I know which size to choose?
Dropouts are the slots your wheel axle sits in. Measure the inside width between them – usually 135 mm for most bikes with quick release. Match this to the option shown on the product page.
3. Does the kit include a battery?
No – batteries are sold separately. You’ll need a compatible battery to power the kit.
4. How long will delivery take?
Express: 2–4 weeks.
Standard: 40–70 days.
Production time is usually 5–10 business days.
5. What’s the difference between sine wave and square wave controllers?
Sine wave: smoother, quieter, better control.
Square wave: stronger punch off the line, a bit louder.
