It’s important to note, that the axle is slightly wider than the tail of the frame. I widened the opening by grinding down just enough metal at the tail work a rotary tool to gain clearance. After that, it took no time to install. As an aside, this presents a perfect opportunity to change your brake pads as well. I was extremely hesitant to buy one of these wheel assembly kits. Many had reviews of non-spinning wheels or other horror stories, but this one did not. I took the jump, and it has worked out perfectly. No more back flats to worry about, and no loss to top speed! The ride is a little bumpier, but i only noticed the first ride or two. Slight decrease to total range as well, but that’ll happen. It fit my M365 perfectly, just had to adjust the brakes to fit this setup. I can not recommend this enough as a quick solution to eliminate flat tires as an issue. I am beyond pleased with my purchase
Loopwheels ($300+) give you that comfortable ride you’ve been looking for. If you have a folding commuter bike like a Dahon Mu Uno, which doesn’t come with its own suspension system, then you neeed to take a look at Loopwheels. These suspension wheels allow you take bumps, curbs, and potholes in comfort with reduced vibration. The Loopwheel doesn’t fit every bike. It’s a 20″ wheel with specific clearance requirements, so check out their Kickstarter page to see if your bike is an option.

Baigh's first prototype design comprised of parts purchased from Home Depot. The idea has since been patented.
“Potholes, cracks, cobbles – when you have chronic pain, you feel every vibration like a knife. Loopwheels took only a second to fit. They definitely reduce the pain of going over bumps, kerbs and cobbles and have made every trip out far more comfortable.”
