Bike Crank Arms,89MM/102MM/114MM/127MM/140MM/152MM/160MM/165MM/170MM/175MM Available in Diamond Hole Bike Crank Arm for Ebike

Really only needed one, but sensibly they are sold in pairs. But they fit correctly.

So I bought one of those new high-power ebikes. It came with a throttle, a cadence sensor, and the worst pedal assist algorithm I've ever felt in my life. I took it for a super fun joyride on dirt at 25mph and laid it out flat when I hit a wet patch, which bent the heck out of the right crank arm. Turns out it came with 120mm crank arms, which are very hard to find, and out of stock at the OEM. So I went looking for literally just a place to put my feet. I found these, and I absolutely love them. I bough them at the 89mm size, though I'd buy them in 0mm if I could. They feel plenty strong, they have superb ground clearance (due to no chainring), and they perfectly fit my standard square taper bottom bracket and standard pedals. If you're looking for literally just somewhere to rest your feet that isn't proprietary nonsense, on your new throttle-equipped ebike, so you can ditch your chain and all the maintenance that comes with it, these'll do you just fine, and for cheap.

This product is as advertised. The branding on the back sides indicate they are from the same line as Tongsheng and Bafang middle motor ebike conversion kits. Please note that the right crank that come with middle motor kits usually do not have an offset as the right square/diamond taper is further from the bikes center than the left. As cranks are not like that they may result in a wider asymmetrical Q factor. This may cause comfort ,efficiency and pain issues. In my case a 16 mm pedal extender might correct the asymmetry at the expense of an even wider overall Q factor. Hopefully they will release right side cranks of of the same varying lengths with no offset.

I like the short throw of the pedals. My electric bike does all the hard pedaling so I don't need the leverage of a longer crank arm.

This set served as a great replacement for crank arms on a road bike. The markings on the crank arms were useful, given the fact that the primary reason as to why I chose to purchase this product was because I foolishly cross-threaded an OEM pedal and crank arm during assembly. Installation was easy, and the price is reasonable for the quality.

No way to attach sprocket. This would work for unicycle.

It was okay but it didn't come with the crank wheel

They are just what I asked for fit my ebike seem as good as the OEM parts thanks
