  • All BBS02B 48v750w motors have a max output of 25a. We program then to produce an output of 20a, this puts less strain on both the motor and battery and increases the life of both.

Benefits of a mid-drive motor compared to a cheaper hub motor:

  • Uses the bikes gears as the engines transmission so the motor can run at the optimum RPM range
  • Increased performance
  • More efficient
  • Better at climbing hills
  • Better weight distribution as the motor is positioned close to the center of gravity and low to the ground
  • Improved handling
  • Easier maintenance and installation
  • A Mid Drive ebike is easier to ride because the extra weight on the wheels of a hub ebike make it tougher to pedal

  • Motor
  • Latest DPC-18 colour display with multiple features
  • Thumb throttle

    Bafang 48V 750W mid drive

    Wow what a great purchase. Install was straightforward, electronics went together like clockwork, gear sensor works amazingly well, and battery is more than capable. First ride today to work -80 km and still 50% charge remaining. Today’s 30km headwind was no bother.

    Bafang BBS02 kit and Sanyo 48v 14ah battery pack

    Posted by Chris on 27th Sep 2020

    I installed this kit and battery pack yesterday in a few hours with basically no issues at all! Components,cables, plugs, hardware etc are all very high quality. This is a very well thought out and professionally made kit. The tutorial on YouTube made installation easy. I do recommend getting the tool kit if you don’t have a crank puller,chain breaker, bottom bracket tool or a bafang motor tool. The standard chainring in my case is suitable for trails and back roads but may be too big at 46 teeth for off road use. I’ve clocked up a whole 20 kms and must say there’s plenty of power here. Hills are flattened easily. I recommend fitting the throttle too. It just adds a bit more control for coasting etc. The colour display shows watts used and speed. A great combo to help you achieve good battery power
    economy. Can’t comment on battery range or durability at this point. I must say that this kit on my old GT aggressor mountain bike sure puts a smile on my face! :)

    i can't believe how easy it was to install and how much fun it is to ride!!! im having a ball. bling ring is essential, worth the extra $$$. as my chain kept jumping off, now quieter and chain is staying where its meant to be.

    BBS02B 48v750w Bafang Mid Drive Kit

    Posted by Kev on 7th Mar 2019

    Excellent kit, once the original crank was removed it was a simple installation. Extremely pleased with the results, just over 55km/h on a flat road without trying. multiple levels of assist are great. Great service, answered any questions I had and quick postage. Highly Recommend
