450W Electric Bicycle Left Drive Conversion Kit - Fits Most City Bikes with Chain Drive

1. Compatibility Notice: Rear V-Brake Required
This conversion kit is designed specifically for bicycles equipped with V-brakes on the rear wheel. It is not compatible with disc brakes or coaster/backpedal brakes. If you are unsure about your bike's brake type, please send us a photo of your bicycle for confirmation before ordering. We will help you select the correct kit.

2. Motor Bracket Fitment & Customization
The included motor bracket may require modification to fit your specific bicycle frame. If you are not comfortable with custom fitting, please send us detailed photos of your bike’s frame and rear dropout area before installation. We can provide guidance or suggest adjustments to ensure proper fitment.

4. Voltage Selection Guide: 24V vs. 36V
The main difference between the 24V and 36V versions is operating current and efficiency. For longer range and more consistent performance, we recommend the 36V kit, which generally offers better battery efficiency and sustained power output.

5. Controller Safety: Fuse Protection
The controller includes 1 fuse wire and 3 spare fuses. If a fuse blows, please note the circumstances (e.g., sudden load, wiring issue) and avoid repeating the same condition. You are welcome to contact us for troubleshooting assistance.

6. Throttle Type Selection
This kit offers two throttle styles:

• Twist Grip Throttle – Select the "key throttle" option.

• Thumb Press Throttle – Select the "thumb throttle" option.
  Please choose according to your riding preference during checkout.

Please note, this item doesn't fit the bicycle that use the coaster brake.
This item is for the bike that uses the hub diameter less than 36mm.
