In my view this is the best way to mount the sprocket on a motorized bicycle . I may need to buy another . Thank you very much . Larry k. ### ⭐⭐⭐⭐⭐ Get this! *by C***S on April 30, 2023* This is better in every way possible, it's easy to install, fits on most if all modern hubs, it's cheap but not cheaply made. I could go on but one thing to know keep the bolts tight. ### ⭐⭐⭐⭐ Fits good only issues is *by A***N on January 25, 2025* The media could not be loaded. Sprocket way smaller than oem part made kinda of a issue .other than that better than the wonky set up that came with kit ## Frequently Bought Together - sthus 40T Sprocket Adapter Fit 415 Chain 49cc 50cc 66cc 80cc 2 Stroke Motorized Bike - sthus Black Spring Loaded Chain Tensioner For 49cc 66cc 80cc Engine Motorized Bike 2 Stroke Engine - HGC 1.0" Compatible Pad For 1.5 Inch CNC Sprocket Adaptor For 1.5" Adaptor 1.5" Hub 60cc 66cc 80cc Motorized Bike (Silver) --- ## 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.com.kw/products/131684859-sthus-40t-sprocket-adapter-fit-415-chain-49cc-50cc-66cc](https://www.desertcart.com.kw/products/131684859-sthus-40t-sprocket-adapter-fit-415-chain-49cc-50cc-66cc) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-15*
