Please make sure your bike light power is within the supported range if using the light function.

This kit is for ebike controller replacement or conversion use. It is not a complete motor kit and does not include battery, motor, wheel, charger, or frame parts.

⚠️ Important Notes

• When using 17A–30A waterproof controllers with a light module, make sure the bike light power ≤ 7.5W; otherwise the light module cannot function.

• The 30A 1000W controller has a different motor connector compared to the 17A/26A. Please check compatibility before purchase.

• Ensure motor connector size and wiring match before installation.
