My background in wheel performance is its circular motion( which involves the circular of the wheel, and that the hub remains in the center of the wheel) if u are rolling with an oblong wheel, then u may actually exert more effort in lifting your self with the bike rather than rolling.
You’ll notice your loopwheel has more movement, vertically and laterally. As soon as the springs are loaded, they compress and further change their concentricity. This is what gives your wheelchair comfort and shock absorption. A Loopwheel is designed to absorb shocks, reduce jolting and cushion your body against vibration. You’ll notice more sideways movement than with a spoked wheel, but you’re trading rigidity for greater comfort.

Previously on bespoken we’ve featured articles on manual and motorised chairs which help the user negotiate uneven streets and rougher pathway, but a lot of them have been both expensive and a bit impractical for day-to-day use. A new Kickstarter, Loopwheels, addresses this problem with a simple and far more affordable design. Loopwheels contain integral suspension meaning the wheels absorb more shock than a standard wheel and allow the user to negotiate tougher terrains with greater ease and comfort. The Kickstarter also says that they can be fitted onto most standard wheelchairs. Following up from a successful campaign to raise funds for the Loopwheel as a bike wheel, this latest project has already raised over half of its £16,000 goal with 28 days left to go.
As far as treads go, the sky's the limit. Treads bolt directly onto the outer rim piece by piece, and there are a bunch of options to choose from, including a range of pre-molded road retread options by companies such as Michelin that bolt on in sections, or a plethora of heavy-duty industrial options that use polyurethane, urethane or steel pieces in a range of different configurations for serious off-road grab.
