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 ## 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.fr/products/96713466-crank-arm-left-available-in-diamond-hole-and-square-hole](https://www.desertcart.fr/products/96713466-crank-arm-left-available-in-diamond-hole-and-square-hole) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-22*
