Product Description

Easy Installation and Variety of Motors

With the Bafang 8FUN BBS-02 mid drive system you never have to unplug the hub motor to remove a wheel and you can easily change the mid drive from any size bike to any other size bike with little effort.

The BBS-02 also has the widest range of power offerings in their mid drive systems. They make available a 250, 350, 500 and 750 watt systems in 36 and 48 volt power ranges.

Pedal Electric or Throttle

The controller, which is built into the mid drive uses the latest sine wave technology for a smooth, quiet and efficient ride. From the console you have 3 levels of assist as standard to choose from but can be re-programed by the user with up to 9 levels of assist + “0” zero level for no assist. Another feature found in the BBS-02 is a double clutch design that allows a rider to use the pedal assist, in what ever assist level they choose, or engage the thumb throttle for up to 50% more assistance for climbing those hills. The rider can use the thumb throttle for power assist only if they desire without the pedals turning.

A feature long overdue and one intended for the American rider.


Every rider has experience a chain coming off the sprockets from time to time. It’s normally no big deal, just stop and put it back on.

However, with any ebike that is using “Pedal Assist”, you need to change your habits. “Turn OFF” the power to the motor before attempting to re-install the chain. Why? Because any movement of the chain ring can alert the controller that you are pedaling and it could turn on the motor and become a potential hazard.

Enjoy your ebike and ride safely!

    I’ve had the 750W kit on my old Cannondale F1000 for several months now and can say it is a great kit. It replaced a Bionx kit that went bad after about a year (not worth fixing) and it is definitely an upgrade. More powerful, less noise, more flexible (uses the rear derailleur), and better balance (mid-drive). It also has a throttle control that lets me use the electric drive as an assist, or as the primary drive.
    The control unit is comprehensive, with all the information needed, and the brake levers have integrated disconnect switches to shut off the drive when braking. Doesn’t do regenerative braking like the Bionx, but it also doesn’t have the rotating mass (and resistance) when free pedalling….worthwhile trade-off IMO.
    Using the automatic mode can result in some delay when changing between braking and pedaling, but I use the throttle most of the time so it doesn’t matter to me. I can cruise easily at (or above) 20 mph with very little effort, even on a mountain bike with 26×2.4 knobby tires.
    Installation was easy, with everything needed included in the kit, but I found that the drive unit would rotate no matter how tight I made the BB ring. I added a hard rubber bumper between the drive and the downtube as a stop and the problem is solved.
    Overall, I would recommend this kit and California e-Bike.
