There are 2 kinds of battery provided for your choice, 48V or 36V, which matches the corresponding motor you choose.

  • 48V/17.5Ah battery and 750W/48V motor, the cycling mileage under pure electric bike mode per full charging is 45 to 55 (km), and under pedal assisted mode is 90 to 110 (km);

The most important is you can get an eBike for the price of a high-end motor kit. This may be the most cost effective way with most choices to get an electric bike on the market except modifying your own bike.

What are the parts?

So, let's talk about what is inside a Bafang mid drive motor kit package.

First there is a motor and a pack of screws for mounting. Then the display, Varstrom offers many displays as options. Then the battery it is. And then a waterproof 1T4 EB-Bus cable, the cable is used to connect the motor to the display, thumb throttle and eBrake levers. Then we'll have a chainwheel and cranks for this motor, and the chainwheel and cranks are customized to be used on the eBike conversion kits, you don’t need to use the chainwheel or cranks from your bike. The gear sensor will cut the power of the system when the rider shifts gears. Next is the eBrake levers or the eBreak sensor, if the customer wants to keep their own brake levers, you can choose the eBrake sensors. Then there is the speed sensor set for recording speed and mileage information for the system. There is also a thumb throttle for controlling the output of the motor.

At the same time, Varstrom offers some gift for our customers such as the 36V/250W stickerbracket wrench, crank puller, XT60 connector cable for BBS01 or BBS02 or Anderson cable for BBSHD, headlight, gloves, cable ties, 73mm screws (for 73mm bracket) and the user manual.
