Charge your battery for a few minutes and it will be ready for normal use ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sprocket broke within first 5 minutes from start *by A***A on 17 February 2025* ### ⭐⭐⭐⭐⭐ A+++ *by M***R on 12 February 2026* ### ⭐⭐⭐⭐ Harness Tampered With *by L***D on 23 March 2026* ## Frequently Bought Together - Kunray Electric Brushless DC Motor 72V 5000W Electric Dirt Bike Motor Peak 6900rpm Peak 10KW for Go Kart Razor Upgrade Kit Motorcycle and More (Upgraded Brushless DC Motor, 72V 5000W) - ODI Downhill Number Plate, Ag, Black - YOXUFA T8F Chain 116 Links 54T Rear Sprocket 54mm Bore with Chain Breaker for 43cc 47cc 49cc 2 Stroke SSR SX50 Scooter Syx Mini Moto Holeshot Metotec ATV Pocket Bike Quad Dirt Bike Parts --- ## 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.vn/products/741252466-kunray-electric-brushless-dc-motor-72v-5000w-electric-dirt-bike](https://www.desertcart.vn/products/741252466-kunray-electric-brushless-dc-motor-72v-5000w-electric-dirt-bike) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
