Bafang has never exactly been known for building timid e-bike motors, but its latest pair of high-performance e-MTB drives takes things to a whole new level. We’re talking up to 1,700 watts of peak power, 150 Nm of torque, and 800% pedal assistance.

At that point, “pedal assist” is starting to do some pretty heavy lifting as a phrase.

The new Bafang M510RS and M560RS are production versions of motors first shown as concepts at Eurobike last year. They’re set to make their official production debut at the Italian Bike Festival in Misano, Italy, September 4-6, ahead of series production later this year.

The slightly more reasonable of the two – and I’m using “reasonable” rather generously here – is the M510RS. It offers 110 Nm of peak torque during normal operation, while Bafang’s temporary Boost-to-Limit function can push that as high as 120-130 Nm depending on the system voltage. Peak power reaches 1,100W on a 36V system or 1,300W at 48V.

Then there’s the M560RS, which is where things start getting particularly bonkers.

That motor produces 120 Nm normally, increasing to as much as 150 Nm in Boost-to-Limit mode. A 36V setup can deliver 1,400W of peak power, while the 48V version cranks that figure all the way up to 1,700W. All of that, yet the motor weighs just 3.3 kg (7.3 lb). Sure, chunky for an e-bike – but not that bad in absolute terms.

To put that into perspective, there are plenty of regular commuter e-bikes running around with 350W or 500W motors.
