These cranks will not work on a Bafang M620 Motor, the motor uses a proprietary spline and these are ISIS splined. They look awesome though!

To echo another reviewer before me - it is amazing being able to find shorter cranks for the Bafang 600 series motor (proprietary here on Amazon!! I was surprised to find that these EXACTLY matched the OEM cranks that were on my bike - even going just from 170mm to 160mm, I found the shorter crank arms practically eliminated the pedal strokes I'd previously been having on my Ebike, as well as improved my overall comfort spinning on the bike, especially while climbing!Previously I had tried 150, 152, & 155mm cranks on some of my other Ebikes, but being 5'11", the 150 & 152 always felt too short, like I didn't have enough leverage. The 155 was tolerable, however the 160 def hit the sweet spot for me, the perfect balance of power & ground clearance as well as feeling easier on my knees — I couldn't be happier!

I've only been using them for a few weeks (5-6 rides so far), but they've been great replacements. I needed a longer crank set for my ebike & these have been perfect.

Seems to be of good quality. It's hard to find cranks for bafang motors. Needed these to be smaller but that was an error on my end. Once the smaller size arrives they will work nicely.

This may seem trivial but finding shorter cranks for the Bafang 600 series motor on Amazon is an amazing thing. Bafang themselves seem to only have two sizes, very few places carry them and if you wanted any shorter you were out of luck. This is also a non-standard in the biking industry so no other cranks exist for it.These fit great and reduced crank length, so far I have noticed a decrease in pedal strikes and no noticeable issues with stroke power.Thanks Prowheel!

Only 3 stars because the arms fit great, but the crank screws included do not fit the M510 motor. Cranks are not original Bafang, but good quality. They also fit the motor well. Just the included crank screws are too little.

Install was super easy and almost tool free - no need for a crank puller if you're replacing cranks with the same installation method. You just need a hex key to turn the screws.These cranks are well-machined and feel just as solid as the ones I replaced. There was nothing wrong with my old cranks but they were 170 mm and I kept bottoming out on trails. My e-mtb doesn't need the extra torque that a longer crank will provide, so I switched to 152 mm cranks to give myself a little more room going over obstacles.These are a solid replacement.
