If it’s a diamond hole, then here it is. There are similar answers, as I looked up a YouTube video on how to disassemble one, and there was a diamond hole featured for one second. So if this answers your question, then I’m glad to help. **Q: Does this work on the bafang e-bike?** A: There are many Bafang E-Bikes, you need to see if yours has a diamond hole or squared one if you take out the bolt for your arm crank. Then you measure the size of the hole in the arm crank. **Q: Do I need to buy a bolt separately?** A: If your original bolt OK can use the original bolt, if not, you may need to purchase separately. Thank you for your question. **Q: Would this work for a Schwinn IC3?** A: No it will not. The IC3 diamond is larger ## Customer Reviews ### ⭐⭐⭐⭐⭐ Item fit perfectly. *by B***R on Reviewed in Canada 🇨🇦 on 23 July 2022* Item fit perfectly to replace the damaged on on my son's bike. Be careful to select the correct crank axle fit. They are either square or diamond (rotated square). ### ⭐⭐⭐⭐⭐ Got me back on the road *by R***R on Reviewed in Canada 🇨🇦 on 24 July 2020* My bike is older (but I like it). This got me going and the quality is good. ### ⭐⭐⭐⭐ 3.5 stars Need a special tool *by B***M on Reviewed in the United States 🇺🇸 on 25 August 2022* This Crank arm seemed to be as heavy duty as the original on my DMASUN spin bike. While riding my bike the pedal started to feel funny, but I couldn't see the problem. I should have persisted, because the pedal was becoming unscrewed and my weight bent it down--stripping the crank arm hole. Quite a learning curve to figure out what the part name was, which shape hole we needed to order. When you're determining diamond or square shape, your crank arm should be straight down. Then after receiving, we couldn't remove the old crank. Had to search the internet to find out that you need a special crank removal tool. I feel that would be important to highlight in the part description. As you can see there seems to be a little Gap that I don't see on the other crank arm. You can see a gap with Grease. All this resulted in 2 weeks of no spinning! After a 40-minute ride, everything still seems good. Will update later if it changes. ## Frequently Bought Together - Epessa Crank Arm Left Available in Diamond Hole and Square Hole,170mm - Skylety Crank Remover Bicycle Crank Puller Bike Crankset Crank Arm Puller Compact Crank Puller Cycling Power Pull Crank Pulley Tool Repair Maintenance Remover for Bikes, Black - Hapleby Premium Bike Pedals of 9/16 Inch, Professional Mountain and Road Bike Flat Pedal with 2 Sealed Bearings, Wide Paltform and Lightweight of Bicycle Pedals, Come with Pedal Wrench 1PCS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/378388075-epessa-crank-arm-left-available-in-diamond-hole-and-square](https://www.desertcart.vu/products/378388075-epessa-crank-arm-left-available-in-diamond-hole-and-square) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
