Product Description


Designed, Engineered and Made in Australia. We are super E-bikes!


This bike is going to blow your mind away. It is swift, agile and powerful. The one and only dual suspension super E. fat bike - the ultimate machine. In the past few years, we often get the request to make an ultimate fat electric bike with a torque sensor motor. The monster has arrived.





Australia's first mind-blowing 35amps controller - VOLT Exclusive

  • VOLT upgraded the motor's firmware to bring you the peaking 2000watts  & unreal 180N.M of torque !
  • Trying is believing.  "This motor equipped with the torque sensor just feels so much better" - Daniel Djoenaidi (Sydney)
  • Bafang G510/M620 uses tri-sensors to assist your ride including torque sensor, speed sensor & cadence sensor.
  • The G510 motor core is physically larger than any motor out there. One will be utterly impressed by its uncompromising torque power!



Which Max Jumbo is for me ?
  • 650Wh or 910Wh battery ? Contrary to their numbers,  both have the same weight and size ! It also depends on if the ride is 25kmh+ or 50Km+
  • Standard (MT) Stem vs Adjustable Stems? The standard bike stem is lighter. The adjustable stem allows infinite angles and customised riding comfort.
  • Droppost vs No Droppost ?  Droppost is amazing; must have.





Who builds this bike for you ?

Each "XT" is hand-built by VOLT to our new 2019 manufacturing standard. Made in Australia.

CASSETTE VERSION. Users are almost required to have some mountain bike experience before to operate this "monster".


  • Bafang M620 /G510 Drive System. Peak 2000watts. Up to 180N.M of Torque. 35Amps Controller Setting (off road enduro riding ONLY)
  • Battery - Downtube style with 3 bolts and soldered on holes to reduce the battery shake-ness. 
  • Suspensions: 130mm travel VOLT Air Fork  & 130mm travel DNM Air Shock Designed in Germany. Made in Taiwan
  • Gears - 1 x 7 Speeds (13T -34T) Modified Shimano DEORE  9 System with 11t blocked and 40T blocked

Why is VOLT promoting fewer gears?

  • Most importantly, it is because of the reliability.
  • Even the best 10 - 12 speed cassettes can not handle any 1000W+ power. They will wear out pre-maturely within weeks!
  • E.bikes do not need 10+ gears. Almost all E-cars and motorbikes are single speeds.
  • We blocked the furthest two gears to improve the chain line angle within the "good" range
  • We want to shift from the high torque gear to the high speed gear as fast as possible. 5 speed shifting is ideal. 7 speeds is tolerable. 12 speeds is "annoying"





How does this motor compare with Bosch, Shimano, Brose, Yamaha.... ?


  • The motor facilitates a wide range of  power and fun from e-push bike to e-motorbike. Choices are buttons away.
  • 10 levels of power settings cater all types of needs from the min assist to the motorbike experience.
  • Equally intuitive with sensors purchased directly from German suppliers
  • Quiet as well considering the amount power it outputs
  • Unrestricted yet controlled pure madness this motor is. Our exclusive firmware 52V/35A is better than the stock 48V/30A version




Who are BAFANG Mid Drive ?    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 also stock the full range of spare parts to provide on going support for our customers.

Bafang has a range of products. If you want a powerful motor, VOLT only recommends the reliable M620 & M615.






Why Choose VOLT 52V Lithium Engineered in Australia ?


52V is stronger than 48V. It taps out the "hidden" 8% power of a 48V motor system.

We have made and sold over 1000+ electric bike batteries. We are always in the process of  improving the battery production & performance from customers' feedback. The feedback goes directly to our own VOLT operate factory in KunShan, China. We have engineered and made our own BMS in Shenzhen. They are compact & heavy duty. Our service team is rich in experience dealing with modern electric bike batteries.

Bicycle Size & Gear Question

Most motorcycles or scooters come in one size only. Ebikes with a powerful motor eliminate the need for too many 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.


E-Power mades gears redundant. Electric bikes only need 3 - 5 gears just like a motorcycle or a car.





What makes us " Made in Australia" 

Yes. Most parts are imported from Asia/ Europe. but many were to our own requirements and design. We believe in our idea of having the in-house production. It gives us the quality control and the learning ground to improve on engineering & performance.  We've built the first 1000 e.bikes in Sydney. And, we will continue to built more.
