PROWHEEL Bike Crank Arm,One Pair Universal 152MM/160MM/165MM/170MM/175MM BCD 104MM Square Hole Bike Crank Arm for City Bike,Road Bike,Folding Bike,Mountain Bike,Ebike

I ordered this crank arm set that described itself as Prowheel. I don't know if the arm arms says Prowheel on it but the fit is very precise of everything I bought. I did this because a car hit my bike and it needed a few repairs. I decided to order more than it needed. These arms are almost the same size as the Sunrace arms, but they are more light weight. I hope it is strong enough. I like the spider grip on the chain ring. The Sunrace crank arms did not have as much of a wide grip on the previous chain ring and it was all once piece on the right side. I do not know if I could have got any better if I tried to adjust what they bike store did. I did not try to modify what they did. The metal would make an unwanted noise when I was standing and pedaling, but when I was sitting I did not notice it, but I said I would just roll with it. But now due to unfortunate impact with someone who is at fault for hitting me, with their car, near the high school, I have thought I would try to replace the crank arms myself. I have done a good job, but my elbow hurts because it rang into somebody's BMW and I hope it will heal without infection. All I really needed was 1 crank arm and a pedal to make the bike function. But I did take the bike to the shop again anyway to have them check things over. I asked them to service the front brake and I gave them some new tires to install. The experts there are also going to try to make the front wheel more straight spinning. To briefly summarize, I used a crank remover I bought on Amazon and it worked properly. To be fair I never tried to check how tight everything was on the previous crank system, but what I know is that now after the work I did myself, replacing whatever was there, my bike operates flawlessly with no unwanted noises.

These were a nearly identical replacement for the crank arms on my Cannondale Quick 2. Specs are identical (165mm). Only slight cosmetic differences.

I wanted to try a shorter crank length and this was the only listing on Amazon that has a great selection. The price was reasonable but it would have been better if it was a multi speed crank.

I am getting older (aren’t we all); I am presently old enough to realize I am getting older (maturity?). That said, I am taking steps now to ensure I get to enjoy activities, like riding a bike, well into my future. Shorter crank arms have less stress on joints; I have switched several to 165-mm length and continue to do so.Sometimes when switching cranks, you have A LOT of complexity. Bottom Bracket standards and widths, cranksets that only correspond to certain widths, etc. You know what is easy? Square Taper. The bottom bracket is separate from the crank arms. And that is what these are, square taper. So, if you have a square taper bottom bracket, you are in luck. If you don’t have a square taper bottom bracket, these simply do not work for you. The description says “Universal” but make sure you have a square taper bottom bracket before ordering or it simply won’t work.These are not lightweight, but they appear plenty strong. Seriously, if you are a weight weenie you aren’t using square taper bottom bracket.The spider on these is set up for a 2x drivetrain. You may slightly alter your chain line and need to adjust your front derailleur. Watch a video, not difficult. If you are 1x drivetrain; again not for you.

So these aren't the lightest or best looking but they're light years ahead of the junk that comes on sub $2k ebikes. I installed these arms along with a narrow/wide 32 tooth chainring on my Lectric Xpeak to actually get proper gearing on this bike. So far they seem strong and the finish is holding up. If any issues arise I will update this review

Works

Crank stripped after 2 months of use. Unable to return now. Really disappointing product

These are beefy and get the job done in style. it would have been nice if they would have included some crank bolts. Other than that, they are good crank arms.
