Simply cutting the plugs alignment key with a razorblade allowed me to plug it in with a different pin on top, and then the throttle worked. Easy fix ### ⭐ Does not work with Himiway ebikes *by C***S on September 18, 2022* Kept getting an error code and would not engage motor. ### ⭐⭐⭐⭐⭐ Works Great! *by S***R on February 14, 2022* I accidentally smashed my original thumb throttle. Oops. This one is affordable and works great! The red/black/yellow wires don't exactly match the red/black/white wires from my controller. But I connected the reds, the blacks, and the yellow to the white and it worked fine! --- ## 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/94356357-wuxing-electric-bicycle-thumb-throttle-ft-21x-finger-throttle-accelerator](https://www.desertcart.vu/products/94356357-wuxing-electric-bicycle-thumb-throttle-ft-21x-finger-throttle-accelerator) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
