Who are BAFANG ?    Best & Only Powerful Mid Drive Motors


Most influential Brands of E.bike motors are Bosch (Germany), Brose (Germany), Shimano (Japan),  Yamaha (Japan) and then the Bafang from China.

We have chosen Bafang for a few reasons. It is the most reputable, experienced and "strongest" manufacturer in China and more importantly, the only and best high current / power electric motor producer in the world.


  • We import directly from the factory and we rebuilt the motor with better greasing and screws check in Sydney.
  • We tune the motor controller with our own tested settings for the performance our customers want.
  • We own and operate our own lithium battery assembly factory in KunShan, China to guarantee that the final quality check is up to our standard.
  • We are also capable to strip down the motor and battery for the servicing and repair.  We stock all parts for our customers and dealers to provide our nation wide support.


On the market, there are also hub motor E.bikes. No vehicles have motor in their wheels for a reason. The mid drive motor send the power through the chain to facilitate the 7-11 gears. Having gears is beneficial. Climbing hills is more efficient (or possible)


Motor Name M400 Peaking 900watts ( 3-4 year + old Model)

  • Pedal Assist & throttle enabled BAFANG motor.
  • Peak 900Watts 52V 17A. Programmed settings.


Please note Bafang Motor 250watts 350Watts 500Watts 750watts 1000watts are just stickers. We tune the "blank" motor core and thus setting the "watts" ourselves to any number - usually 250watts , 1000watts or 1500watts.




Engineered In Australia 48V Battery/ Range


Pairing a 52Volts battery with a 48V motor has many benefits.  It is like bring an adult to a teenage fight. The performance will be enhanced. The battery will bear less stress and produce less heat. The battery will remain potent longer.

VOLT batteries (so do most modern batteries) have a Battery-Management-System (BMS) chip to regular and balance the charing and discharging for both performance and longevity. But, our BMS chips (from Shenzhen) have already been tested to be efficient and enduring.


"Spark" uses 48V integrated batteries (not 52V)

  1. 12.5Ah 48V CN Cells 600Wh. On average riders can get up to 60km range
  2. 17.5Ah 48V Samsung Cells 840Wh.  Up to 100Km Range.
  3. 21ah 48V Panasonic Cells 1000Wh. Up to 140Km Range. Please be aware this case is physically larger than other two sizes.


For the reference, Bosch or Shimano battery pack is 500watt-hour 36V.

Bicycle Size & Gear Question

Most motorcycles or scooters come in one size only. Ebikes with a powerful motor eliminate the need for different bicycle frame sizes. We use L size frames but we can install shorter or longer stems to accommodate shorter and taller riders. Leave us a note.


Similarly, most cars or motorcycles would not have more than 5 gears, it is true for ebikes as well. E-bikes actually do not need more than 5. We have chosen 8/9 speeds because no manufacturer is making 5 speeds drive systems.
