This is a complete conversion kit to convert your bike to an electric bike. This 750W electric bike kit is based around the Bafang H640 / G0900 geared rear hub motor. It’s a high-power, yet small form factor ensures the conversion looks neat and tidy, but the motor packs a big punch when it comes to torque. Bafang motors are well known for their reliability and repairability, which is why we choose to sell them on this website.Â
You have a choice of whether the motor is loose, ready for you to build into your own custom wheel, or pre-built to a rim size that suits your bike. Make sure you select the correct rim size for your bike. A high-capacity Hailong Lithium-Ion battery is included, which will enable more range or miles before needing to recharge. The higher voltage of 52V means the kit provides a higher torque, enabling faster acceleration and better hill-climbing ability. If you wish to choose a different handlebar display or throttle option, then please get in touch and we can make a custom bundle for you.

IMPORTANT NOTES – This kit is not road legal in the UK as it is above the allowed wattage and the speed is not limited. For our road legal version click HERE. Occasionally, Hailong battery frame mounts do not align with the 2 bottle cage mount points. There must be a minimum of 2 bolts securely holding the battery mount to the frame. If you find that the mount does not align correctly, you will need to purchase the Grin Tech battery bob mounting adapter that we also sell HERE. Make sure you use the supplied bolts for attaching your disc rotors. Otherwise, if they are too long they can grind internally and prevent the motor from rotating.
This kit can only be sent to England, Scotland and Wales due to the Lithium Battery
