Don't get me wrong, that is a great motor, but off-road, you'd be left with either buying $2000+ worth of suspension, or sticking to the road. That much rear wheel weight causes slippage from bouncing off bumps and dips. The QS205 on the other hand, has performed amazingly. The 5T model with 145a (w/ 450 Phase amps) has been a monster at the local dirt track, easily getting me up to 45mph+ on straight sections. I have this in an Electric Enduro-Style Bike (Heavy Steel, easier to weld repair), and it makes this almost 200lb bike feel like my first aluminum full-susp eBike I built (sub 140lb bike). I had one set of hubsinks on that I've used for years now between builds, but saw that it might benefit me to utilize two sets so I bought another to help with the cooling surface area. Time to go rip at max for longer ;-) Review: Worth the money. A new motor cost more - Fits 9c direct drive hub motor barely. 9c motors are used on most 1000 -1500 watt kits. I found it you bend the tabs with the bolt holes slightly away from each other so when you bolt them it pulls it tighter it's a perfect fit. I also slightly sanded the tabs where they press together to give it just a little more clearance to pull together when tightening bolts. I also added washers to the bolt side and nut side to have more surface area pulling the tabs together. The parts are made very well and the curve of the heat sink matches the hub motor perfectly witch allows you to use a minimal amount of thermal grease to be an efficient and effective thermal conductor. This hub sink combined with statorade is a no brainer if you want to protect your motor, keep it cool, and get better range and efficiency. Heat is wasted energy. It's a proven fact. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D7VLNBL8 | | Best Sellers Rank | #833 in Heatsinks | | Brand | Legion | | Brand Name | Legion | | Cooler Heatsink Compatibility | QS205 | | Cooler Heatsink Material | Aluminum | | Customer Reviews | 4.5 out of 5 stars 12 Reviews | | Included Components | HubSinks | | Item Type Name | HubSink | | Manufacturer | HubSink | | Model | QS205 | | Mounting Type | PCB Mount | | Part Number | HubSink V2 | | UPC | 198715654943 | | Warranty Description | Original Manufacturer Warranty | ## Product Details - **Brand:** Legion - **Cooler Heatsink Compatibility:** QS205 - **Cooler Heatsink Material:** Aluminum - **Manufacturer:** HubSink - **Mounting Type:** PCB Mount ## Images ![HubSink V2 E-Bike Hub Motor Heatsink for Improved Cooling and Performance (QS205) - Image 1](https://m.media-amazon.com/images/I/71GtBkM7bkL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Necessary Upgrade for High-Power Hub Motors *by X***H on May 3, 2025* Hubsinks (and Statorade) have saved me from having to buy a heavy and expensive QS275.

I installed these on my custom QS205 stealth bomber, and they were super easy to install. I also injected statorade into the hub motor, to maximize cooling since I’m pushing over 10KW of continuous power. After doing some testing on steep hill climbs, the motor was still cool to the touch. The hubsinks definitely did its job! ## Frequently Bought Together - HubSink V2 E-Bike Hub Motor Heatsink for Improved Cooling and Performance (QS205) - Grin Technologies Statorade Electric Bike Hub Motor Cooling Ferrofluid (10 Ml) --- ## 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.tn/products/643287414-hubsink-v2-e-bike-hub-motor-heatsink-for-improved-cooling](https://www.desertcart.tn/products/643287414-hubsink-v2-e-bike-hub-motor-heatsink-for-improved-cooling) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-30*
