Ebike Crank Arm Available in Diamond Hole | 89MM/102MM/114MM/127MM/140MM/152MM/160MM/165MM/170MM/175MM for Electric Bike/Commuter Bike/Exercise Bike/Fat Bike

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.

I converted my recumbent trike to electric two years ago using a Bafang kit through Amazon. No issues with the kit and it's been trouble free. The kit is made for a bicycle, not a trike but it fits well except for having to extend the wiring harness to the speed sensor. The Bafang pedal arms may be better suited to a bicycle than a trike. The arms were very straight and 170mm in length. In order to clear the heel straps that are safety equipment on a Terra Trike, the pedals need to have a curve or arc to them. Alps2Ocean made such a product and work perfectly. I ordered 160mm arms because I sometimes have issues with heel strikes. Doing the math 10mm difference is only 1/4" shorter but that makes a huge difference. I am very pleased with these arms. For reasons I cannot explain they seem to reduce knee and ankle comfort as well. I'm a happy guy. The response time was great as they arrived the next day. Installation was easy as well. Kudos to Amazons AI which answered many of my questions before purchase.

Well made, well finished, good replacement arms at a good very good price. Excellent for TSDZ2 replacements.

Worked well and fit my bike

work great, good quality

Very good quality

Esto es una basura me mandaron algo ya usado y dañado no lo devolveré para evitar el costo de mi tiempo Pero es una basura cero estrellas

works fine on my stationary bike. i dont love these but for the price point and the fact that they work i have no complaints. my ideal replacement would be something brand name made from high quality aluminum alloy, hard to justify a higher cost on a used stationary bike that cost me $35 - only reason im replacing existing is threads to remove old crank got damaged on removal

Perfette, uguali a quelle che già avevo. Montaggio facile e veloce.

Absolutely a perfect fit , good price and high quality

Easy to install and is a good replacement for our stationary bike.

Compré el modelo 165 para reemplazar los de mi bicicleta estática que se rompieron. Encajan a la perfección. Producto de calidad con un acabado impecable, muy superior a los de hierro básicos.

Passt perfekt, pünktliche Lieferung
