Solid Replacement for Ebike Repairs
Fit my mid-drive system perfectly. Durable aluminum and the finish looks clean. Feels sturdy even under torque — no creaks, no issues. Just make sure to double check sizing.

152mm Made a huge differance
These are not the most pleasing to the eye but the quality is pretty good for the price one of the arms had poor threads for the self extracting bolt I already had and had to chase the threads with a steel extractor before installing them.

Big bang for the buck.
Taking a star off because the first order came with two different size cranks (152/160mm). Amazon replaced with a new set of 152mm. So far so good on my Yamaha motor. Less knee pain and haven't had a single pedal strike.

152mm the hype is real
Swapped out the stock 165mm cranks on my Niner WFO ebike for some 152mm. Believe the hype shorter cranks on ebikes are awesome! I'm 5'11 and these shorty's made steep hill climbs a breeze the power delivery is instantaneous and less pedel strikes. Cranks are pretty basic,but I didn't want to spend big money on dev 5 cranks just to test the feel of shorter cranks.

Wrong size for motor shaft
This item is for a Bosch Gen 2/4 motor. I have a Gen 3 motor. Arms did not fit my motor. Returned for refund.

Well made and durable.
Well made for the price. Been using them on my emtb, and they've held up great to the abuse! Appreciate all the lengths available, though a 135 would have been useful!
