450W Electric Bicycle Left Drive Conversion Kit - Universal Chain Drive Installation for Most City Bikes with Spoke Chain Wheel

【Important Notices】

1. Brake Compatibility
This conversion kit is only suitable for bicycles equipped with rear V-brakes. It is not compatible with disc brakes or coaster brakes. If you are unsure about your bike's brake type, please provide a photo so we can verify compatibility and recommend an appropriate kit.

2. Bracket Fit & Adjustment
The motor bracket may not perfectly fit your bicycle frame and may require modification during installation. If you need guidance on adjusting the bracket, please send us a photo of your bike frame for personalized suggestions.

4. Voltage Selection Guide (24V vs 36V)
The primary difference between the 24V and 36V systems lies in operating current: the 36V kit runs at a lower current for the same power output, generally offering longer range and improved efficiency. For extended riding distance, we recommend selecting the 36V kit.

5. Fuse & Safety Notes
The controller includes one fuse wire and three spare fuses. If a fuse blows, we advise identifying the cause (e.g., overloading or a short circuit) to prevent recurrence. Should you require further assistance, please feel free to contact us.

6. Throttle Options
This product offers two throttle types. Please select according to your preference when ordering:

• Twist Throttle (rotating): Choose the "Key Throttle" option.

• Thumb Throttle (press-type): Choose the "Thumb Throttle" option.

• 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.
  Important:
  This item doesn't include battery or charger.
