Ebike ISIS Crank Arm,127MM/140MM/152MM/160MM/170MM/175MM Electric Bicycle Crank Arm for ISIS Mid Drive Motor,Bosch GEN4,Yamaha PW-X3/PW-X2,BANGFANG M620,Brose Standard/MAG,Panasonic GX0

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.

Great for the price

Fits Gen 3 Levo Comp well, but still get pedal strikes, though less frequently and with less intensity. Maybe should’ve gone another 10mm shorter. Quality seems good, but fit and finish aren’t on par with what the bike came with - at this price point, you shouldn’t be surprised by this. Durability has been OK, will update as more miles are added. Overall, a good option to consider, if you’re looking to shorten crank length and reduce the pedals bouncing off stuff on the trail.

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.

My wife bent a crank arm on her Scott E-bike with Bosch motor. These fit perfectly and installed easily as long as you have the special crank arm puller tool. I like that I had optional lengths available like this one (slightly shorter to try to reduce pedal strikes). They look good and seem to be of good quality. They function perfectly and so far they have held up well.

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.

I used them on my Electra Cafe Moto Go with a Gen 4 Bosch motor. I was attempting to put on new pedals and wiped out a pedal bolt which got me looking for replacement arms. I actually prefer 165 mm over the standard 170 and 172 lengths as I believe that is my sweet spot for spinning. You will need a 8mm wrench, a pedal wrench, and a crank arm puller. Pretty straight forward, remove bolts, insert arm puller, remove arm, then reverse order to put these on. They were machined perfect and work great. It will take you some umph to tighten the new ones on. As a matter of fact I re-snugged them after I took a quick ride. Would buy again.

Easy to install and comes with the bolts required. I had a self extracting bolt that wouldn't come out so I couldn't use it. Previously bought a different brand and it didn't come with them. Quality seems sturdy.

Worked on my Isis cranks set for my cyc photon.

These cranks fitted straight on my Bosch gen 5 motored ebike without a problem. Being 13mm shorter than the 165mm cranks it came with means way less pedal strikes. It took very little time to get used to the shorter cranks and they appear to be holding up to the off road abuse excellently.

Le quedaron excelente a mi bicicleta recomendados
