Turn your bike into an e-bike - with Bafang motors 

In addition to the normal commercial e-bikes, there are lots of conversion systems available. "Bafang" is one of the leading manufacturers in this area - both for e-components and complete systems.

Functional principle and advantages of Bafang BBS01/02/HD mid-drive motors 

What means mid-drive-motor? 

There are 3 different ways to mount the motor when converting your bike into an E-Bike:

  • Front-wheel (hub motor)
  • Rear-wheel (hub motor)
  • Bottom bracket - in the "middle" (mid-motor, mid-drive motor)

Compared to the hub motor, the mid-drive motor doesn´t transmit the power directly to the wheel, but to the bicycle chain. This means, your rear bicycle gears can also be used with a motor assist, which is not only an advantage when riding uphill. Further advantages are ideal weight distribution, low center of gravity, and a very natural riding experience. Furthermore, the front and rear wheels can still be changed without any problems.

Bafang BBS motor function is very simple: The electric motor powers the front chainring with an internal gear ratio of 22:1. An integrated clutch makes it possible, that the crank arms won´t be moved while the chainring rotates forward.

The Bafang Official Motor Partner

This set is suitable for most bikes. To be sure it fits your bike as well, please note the following points: 

1)Bottom Bracket Size:

Since this motor is available for different bottom bracket widths, please measure your bike and select afterward above. We recommend inverting the bike and measuring the frame width at the bottom bracket.

2) Bottom Bracket Diameter: 

The motor axle has a diameter of 33,5 mm and is installed instead of the bottom bracket. If your bottom bracket width is more than 75 mm, it´s possible that your bottom bracket has a bigger diameter (press-fit bearings) and you need an adapter. We recommend removing your bottom bracket, then you can easily measure the diameter. If it´s about 33/34 mm - no adapter is required. Please send a photo to info@eunorau-ebike.com if you are not sure - we will help you!

Bafang BBS advantages:

  • The motor is very silent
  • Pedaling resistance is very low, even without system operation
  • Bafang BBS motors are very low maintenance
  • Spare parts available and easy to change for yourself (many clips on youtube for assistance)
  • Lots of system components are selectable (chainrings, display, battery, ...)
