Review: Hub sink.. - Fit perfectly. I put two sets together on my hub for optimum cooling efficiency.. I also purchased the qs273 kit and saved the extra sinks for when I get a larger motor . U used these on a qs205 as all the kits will fit the qs205 if you use the 6 full sections and save the extra for another time .
Review: Necessary Upgrade for High-Power Hub Motors - Hubsinks (and Statorade) have saved me from having to buy a heavy and expensive QS275. 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 ;-)

### ⭐⭐⭐⭐⭐ Worth the money. A new motor cost more
*by A***. on April 23, 2025*

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.
