Why Nexus / Internal Gears?


  • A cleaner look
  • Single speed chain is thicker and strongest of all so it rarely gets snapped under extreme stress.
  • There is no side-way chain movement going up and down the cassette. The chain stays on the bike almost forever.
  • Internal gear system itself and the chain suffer from less tear and wear, last longer and require less maintenance.
  • Internal gears can shift standing still without pedaling (at traffic lights)
  • Simple selection 3 gears: climbing (not an issue when pairing any 1000W+ motor), cruising and downhill or speed.


On the other hand,

  • Internal gear smash repair is more complicated - requiring experience.
  • Internal gear is more costly
  • Internal gear can also provide a rich range of gears especially the high end versions.¬†However, it regardless produces less torque at the wheel than a 40T/42T sprocket can do.


In conclusion, if a rider plans to tackle some super difficult mountain riding, a cassette system is still slightly better. For almost every other situation -  internal gears are just better in terms of reliability,  usage and appearance.

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 spare motor 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 M620 Peaking 1600watts ( 1 year + old Model)

  • Pedal Assist & throttle enabled BAFANG G510 motor.
  • Peak 1600Watts 52V 30A. Programmed settings.
  • Tri-sensors: Torque, Speed, Cadence


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 road legal nominal , 1000watts Peak or 1500watts Peak




Engineered In Australia 48V Battery/ Range


VOLT modern batteries have a Battery-Management-System (BMS) chip to regular and balance the charing and discharging for both performance and longevity. Our BMS chips (Made in Shenzhen, China) have already been tested to be efficient and enduring.

Our range estimates are data collected from our customers and are not random numbers. At the end of day, Battery watt-hour number is  what's real.



"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.


What's included in a battery pack ?

  • Battery
  • Battery mount cradle
  • Keys
  • Charger




Bicycle Size Question

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


The motor prefer a smaller 26inch wheel for the higher spinning speed but the (most) rider prefers a bigger 29inch/700c wheel for the pedaling speed. Thus, we settle down on 27.5inch wheels.




What makes us " Made in Australia" 


We begun importing bike from China like most businesses. We used to check and rebuilt more than 50% of the "already built" bikes. Thus, we had the idea of hand-crafting e.bikes locally ourselves for an odd reason - to save time and money


Yes. All parts are imported from Asia/ Europe but many were to our requirements and design. We reflect on issues that thousands of our riders experienced. One example is that high-end bicycle parts are too fragile to bear the motor torque and "thicker" low end parts just do not perform well. To tackle the challenge, we have poured over a quarter of a million into custom making e.bike specific parts.


We believe what makes us "Made In Aus" is our engineering, assembly quality & service.
