Maybe I’m wrong but wouldn’t the wheel react differently every time you hit the same obstacle depending on how the shocks are pointed? Bartthebikeman on May 20th, 2016 - 2:58pm

Loopwheels reduce the level of vibration—“road noise”—through the chair frame and up into the arms, wrists and shoulders.
The revolutionary Loopwheels have been specially designed to help wheelchair users get around more easily and with more comfort. The shock absorbing springs can give you extra power to get up kerbs and reduce jolting as you come down - for a smoother ride wherever you go.

Suspension blocks are the quickest way to provide both, in addition to suspension and turning capabilities, but don't necessarily meet all demands. A rotor can also be used, but has a much lower maximum speed (60rpm, regardless of wheel size) for propulsion purposes - however it can also have its braking torque set to 0 to make it a free-wheeling axle.

Loopwheels are different from spoked wheels. They look, feel and perform differently. You will be used to a wheel being a rigid thing, Loopwheels have flexibility in them in order to provide vibration reduction. The hub moves within the rim as the springs flex. The whole wheel acts as a flexible moving system which constantly adjusts to the load it carries and the obstacles it encounters.

Loopwheels use an off-the-shelf bicycle wheel but removes the spokes in place of a spring system between the hub and the rim for integral suspension. That suspension is made up of three carbon composite springs that act as shock absorbers with 45mm of travel, cushioning the rider for a smooth and comfortable ride. Unlike standard bike suspension systems, it provides tangential suspension, allowing your ride to absorb shocks from all directions — even from the front and rear.
Loopwheels are currently available in a 20-inch size for bikes and a larger size for wheelchairs. They are working on 26- and 29-inch wheels for bicycles. They are currently available as a retrofit for Dahon or Tern foldingbikes and have a 100mm front fork for the changeover. The wheels themselves cost $462 US while a Loopwheels folding bike will set you back $1,493.
We have a wide range of accessories such as quick release axles, tyres and padded carry bags for the wheels. See our accessories page here.

Seconding how compression and rebound get adjusted… Also how will it handle/shed mud? looks like lots of nooks and cranies for mud and debris to hide and cling… I don’t even want to start thinking about what kind of aero properties these bad boys have, … High on my list to try, if I every had the opportunity (’cause dang I’m curious) but low on a buy until the applications for this type of wheel are nailed down.

It's unclear at this point whether you'd lose any forward motion energy due to torque flex, but that can be tuned out of the system if required in any case. It's also unclear how much a pair of wheelchair-sized ASWs would cost at this point. We assume they're not cheap compared to a regular rim and tire setup. Here's some annoyingly infomercial-style video comparing regular wheelchair wheels to an ASW setup over curbs and grassy, uneven terrain.

With every rotation the springs will bend and absorb a amount of energy. Normally this is called “damping”. Its pretty useful in some cases. But it’s pretty unusual to damp a rotation of wheels, because this will slow down the straight moving. For Bicycles (and all other vehicles) you should mount your springs in the direction where the impact is coming from plus a additional damper to stop the bouncing of the spring.

The spokes on a standard spoked wheel hold it in tension. If the spokes lose tension, they start to break and the rim will buckle. A Loopwheel is not held in tension by its springs therefore the rim is strong, double-walled, and less likely to suffer from buckling or fracture at the rim.

When installing the wheels, lugs should be hand-torqued in a star pattern and not installed using an impact tool.
Loopwheels reduce vibrations by up to 70% compared with metal spoked wheels. Our innovative Loopwheel technology now comes with 12% extra hi tech carbon.
Why reinvent the wheel? Because sometimes it makes for a better bike. Loopwheels are a completely new type of bicycle wheel, designed with a unique built-in suspension that makes for a delightfully smooth ride. Instead of spokes, as on a traditional bicycle wheel, the Loopwheels have three loop-shaped springs that allow the wheel to absorb the vibrations and bumps most riders are accustomed to feeling.
I bought the car like this from the dealer. Pretty certain it is stock suspension. The Fronts are 20 x 8.5 and the backs 20 x 10. The front tires are Nankang Untra Sport NS-II 245/35ZR20 and the backs are Nankang Untra Sport NS-II 275/30ZR20. just switched to my winter setup, so i want to move my 20" Here are a couple of pics of my 2009 G37S with stock suspension and 20" wheels. I would love to lower the front some but I am fine with the back and I don't want to get into all the other issues that come up with lowering a car (rubbing, alignment issues, etc etc).
Loving this well made Schwinn! Have many miles of very hard riding on it now and it is holding up well. Zero issues and still functioning perfectly. There is a slight amount of seepage at the front forks but that is normal. I have just about worn out the tires but that is after a lot of miles, most of which were ridden on rough rocky roads with zero flats. Overall this bike is a winner. Well worth the current price.
When you’re on uneven ground, vibrations can wear you out, making it harder to drive your chair and triggering spasms and pain. Loopwheels make travelling over bumpy ground more fun and less tiring.

Hi we are new to a air ride equipped motorhome and are wandering if it is ok to lift the wheels off the ground with the Jack's when leveling on those unlevel sites, the chassis is a Freightliner XC and it seems like the air bags are really stretched if the wheells and everything are pulling down on them in this situation ... We just do not want any damage to the system. Your input would be appreciated thanks The weight of the axle pulls down on the air bags but the weight of the front axle assembly is supported by the length of the shocks. When the shocks become fully extended, air bags, leaf or coil springs, that's when the front axle assembly quits moving down. I'm with everyone that doesn't like the looks of wheels in the air, but it doesn't hurt anything and I have done it. Think about this: The only way your motorcoach can roll away is if it's on the wheels. If it's up on the jacks, it can't roll. A good backhoe operator will hike the rear tires (where the brakes are) up in the air to get it up on the hydraulics where it is solid and stable, before operating. Sometimes they raise the front tires up with the bucket. Ever seen a mobile construction crane? First thing they do is raise all the tires up off the ground to get the unit level and stable before operating. I'm not saying to lift your coach that way, but it's not the big deal that some people try to make it sound like. On my Freightliner with the stiff rear end and V-Ride, if I lift one side a couple inches, the duals will come off the ground. Not a big deal because the jack won't roll.

Today, the Ford Taurus SEL — the top-of-the-line before you get into the high-performance SHO — comes standard with 18 inch wheels. Many buyers select the optional 19-inch wheels, though, which come with Goodyear Eagle RSA 255/45R19 tires. The alpha-numeric soup on the sidewall might not instantly make sense, but compared to what was previously available on the Taurus, that wheel and tire combination is massive.
With standard quick release axles, a choice between 12mm or .5 inch bearings and available in 24" and 25" sizes, Loopwheels fit most manual wheelchairs.

Considering all of the technological advances made in bicycles, cars and trains; the humble wheelchair hasn’t advanced very much since the first one was invented for King Philip II of Spain in 1595. An Israeli startup SoftWheel is about to change that with a bike and wheelchair wheel that is more comfortable and more efficient.When an unfortunate accident left Gilad Woolf with a broken leg and dependent on a wheelchair, the farmer had first hand experience of how uncomfortable wheelchairs can be for the millions of people who rely on them for everyday transportation indoors as well as outdoors.
Sam believes passionately in craftsmanship and in the skills and knowledge that come from practical experience. He worked with a small local company, KG Archery, manufacturers of archery bows, on the development of the springs for loopwheels.

@ Grunchy: Very good question regarding the un-sprung weight. Due to the internal suspension, only about a 1/3 of the total weight of the wheel is un-sprung weight, actually lowering the weight that is 'seen' by the axle. Therefore, even IF the ASW would be heavier overall, the vehicle's drive-train sees far less strain and weight. Forgot your password?
