Motor Technology

BionX motors offer you powerful proportional electric assist in any situation, whether it’s a commute across town in the morning, or a weekend ride through the countryside. But did you know they can also act as a generator to help recharge your battery and boost your range?

All BionX systems come with Regenerative Braking, so when you squeeze your bike’s brake lever, energy is sent back to the Li-Ion batteries, helping them recharge. And if you are traveling down a steep hill and want some extra braking, or want a greater workout as you pedal, switch the BionX system into one of the four Generate Mode levels. You’ll feel resistance, and even more energy is returned to the battery pack.


Proportional Assist

4 levels that work seamlessly with you, offering a safe, natural-feeling ride.


Regenerative Braking

control your descents and recharge the battery as you ride.


Noise & Vibration Free

noise and vibration free motor, so your bike stays a bike and you can enjoy your ride.


motors-cassette-cuSelect BionX motors come equipped with a cassette body, which is compatible with standard 9 or 10 speed SRAM and Shimano cassettes.


  • Keeping the proven strain gauge sensoring on the axle of the rear wheel
  • Smooth, seamless electric assistance
  • Wider range of drivetrain components


Our latest proof of technology is the BionX D-Series motor.

The new distinctive design has enabled our engineering team to think outside of the box and come up with great technical solutions that further promote the BionX DNA of noise and vibration free motors with generate/regenerative braking mode and our proven strain gauge technology. The D-series motor is extremely sporty, lightweight and powerful – sticking to our principle, where an ebike has to ride and feel like a bicycle.

  • Weight: 4.0kg (8.8 lb)
  • Brushless, gearless
  • Generate mode for energy recuperation
  • Integrated torque sensor

Specifications may vary by region.


ITSITS-Technology: Increased Tangential Speed By increasing the diameter of the motor, the magnetic components are placed on a larger circumference thus move at higher tangential speed. ITS is a major contribution to the 250% increase in power output in steady state.
MCRMCR-Technology: Magnetic Component Reduction By increasing the diameter of our motor we need less electrical force to produce torque. This enables us to build a lighter motor. MCR is a major contribution to the 250% increase in power output in steady state.
STC STC-Technology: Spoke To Center Longer spokes enable the wheel to flex more. This means more comfort, more grip and more traction on the trail.

NSC NSC-Technology: Non Structural Cover Extra lightweight construction due to non structural motor covers and a super slim profile
PSGPSG-Technology: Proven Strain Gauge Our Proven Strain Gauge Technology is essential for creating the feeling of smooth, seamless electric assistance that is at the heart of every BionX system.


With a weight of only 3.5kg (7.7 lb), the S-Series motor is 25% lighter than the P-Series motor, while giving you the same great performance.

  • Nominal power: 200W (AU & UK), 250W (EU), 350W (NA)
  • Torque: 9/40 Nm (6.6/29lb-ft)
  • Weight: 3.5kg (7.7 lb)
  • Compatible with 8/9/10 speed cassettes from Shimano or SRAM
