1. Will the bundle fit my bike?
Yes — as long as your bike has open-slotted dropouts and enough space for the battery.
You can find the exact battery dimensions in the product photos.
2. What are dropouts, and how do I know which size to choose?
Dropouts are the slots where your wheel axle sits.
Most bikes use 135mm dropouts — we recommend measuring yours to confirm.
You’ll also need a quick-release rear wheel for compatibility.
3. Do the motor and battery ship together?
No — they are shipped separately due to packaging and carrier restrictions.
You’ll receive separate tracking numbers for each package.

- Express Shipping: 2–4 weeks
- Standard Shipping: 40–70 days
