About G320 BBSHD Peaking 1700Watts (nominal 1000Watts)


Q. Is this motor  the same as the nominal "1000Watts 48V" that others sell ?

A. The motor hardware is the same. The difference is in the controller firmware. Pairing with a 52V battery is 5-10% more powerful than any stock version (48V 1000W) out there. 52V also increases the top speed.

Extra Note: Since Mid 2019,  Bafang has dropped the 52V battery support for the G320(BBSHD) motor. However, motors from VOLT will be updated in Sydney for the 52V battery support before shipping to customers.



Q. What is the top speed and range ?

We set our motor top speed to 50kmh. Removing the speed limit avoids the warranty. However, the theoretical motor top speed for most bikes is 60kmh depending on the road and gear ratio. The range depends on the size of the battery you buy and how you use the motor. The more you depend on the motor , the less range you will get out of the battery. Our range estimate is based on most riders' real world pedalling.


Q.  What is the difference between power and torque ?

Two motors & two bikes consuming the same 1000watts can produce very different acceleration time and torque for the hill. Secondly, the motor power is often discounted when you factor the motor efficiency and drive train efficiency depending on the quality of parts and the engineering effort.

Watts is the energy consumption power on the paper but the real world speed and torque is what really counts "being a powerful system".



Q. Can I buy 52V batteries else where ?

A. Yes. However, our batteries are mapped & engineered in Australia and made by our own factory in China to meet our the safety & performance standards.


Q. Is BBSHD truly better than the older but a bit cheaper BBS0102b

A. 100% so much better. We strongly recommend the BBSHD over BBS0102 ( if you have to do a conversion). HD stands for Heavy Duty. The motor is properly engineered in every way including heat management, gear design & the quality of the components. However,  the best motor title goes to our VOLT re-tuned M620 G510 Peaking 2000watts with the torque sensor.


Q. What is the difference with peak power and nominal power ?

A. The nominal power (watts) is the stable average power out under a medium level of stress - like fast jogging. The peak power is like sprinting - the motor is giving all it has. Both numbers are important. VOLT calculates the peak power using fully charged batteries.


Q. Why does VOLT do the adding high-temp grease, checking the screws as well as adding extra silicone water-sealing gel

A. They are extra work but worth it. Stock motors' grease is inadequate and more is required to make the gears running well longer. Some of the motors brand new out of the box have loose screws on them which worried us and prompted a mandatory check on all new motors. Lastly, water protection is important. Both of the controller and the core are sealed by a thin piece of rubber only. Adding extra gel around the rubber fills up the gap nicely so the motor can last longer in the rain.


Q. Which batteries should I use this to pair ?

A. Ideally, you should use premium cells for 1700watts + motors. Our selection of A-grade Chinese Cells can also handle 1500Watts power max.  In general, low quality and small batteries may not handle the 2000watts well and may grow damaged cells inside.










Who are BAFANG ?    Best & Only Powerful Mid Drive Motors

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

Bafang 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 (Suzhou, China)
  • We rebuilt the motor with better greasing and quality 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 national 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)

VOLT ALSO sells Industry leading 52V 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.


Down-tube Battery Options:

  • (S) 10ah 52v 510watt-hour energy using CN cells. 2A charger / 6 hour charging time. Up to 50-60km
  • (M) 12.5ah 52V 650watt-hour energy using CN cells. 2A charger / 7 hour charging time. Up to 60-80km
  • (L) 14ah 52V 730watt-hour energy using Samsung cells. 5A charger / 3 hour charging time. Up to 80-90km
  • (XL) 17.5ah 52v 910watt-hour energy using Samsung cells. 5A charger / 4 hour charging time. Up to 100-120km


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