Loopwheels reduce the level of vibration—“road noise”—through the chair frame and up into the arms, wrists and shoulders.
The wheelchair application seems to run straight into the eternal problem with sprung wheels. Without dampers, they bounce badly, as sometimes seen in tractors fitted with buckets on a bad road. With dampers, they have very high rolling resistance. I tire needs enough flex to meet the ground, but any further suspension should be on the axle. Lardo January 30, 2018 06:00 PM

For me, base on this design, as long as you can maintain the hub to be: ground to hub distance would always be greater than the hub to the horizontal distance (radius) to the rim. then you should be fine.

Kerbs are less of an obstacle with Loopwheels. Loopwheels reduce jolting, soften the impact of landing, and so can help manage discomfort.
Quicker shift times, a tightened suspension, a 30/70 torque split and sport-tuned stability control empower TRX with the optimal performance-truck setup on paved surfaces.

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.

The University of Texas at Austin Center for Electromechanics (UT-CEM) has conducted a set of simulations and full-scale experiments to determine suitable shock load design requirements for in-hub (wheel) propulsion motors for hybrid and all-electric combat vehicles. The characterization of these design parameters is required due to recent advancements in suspension technology that have made it feasible to greatly increase the tempo of battle. These suspension technologies allow vehicles to traverse off-road terrains with large rms values at greater speeds. As a result, design improvements for survivability of in-hub motors must be considered. Defining the design requirements for the improved survivability of in-hub motors is the driving factor for this research.
You realise in the mining truck example if their estimate of current tyre prices is out by a factor of nearly 3 (as you suggest 38k v 110k) then the whole financial justification falls apart ;) Harmen van Kamp February 2, 2018 12:30 PM

Much like their wheelchair design has made it easier and more comfortable for users to get around in an urban environment, SoftWheel hopes the Fluent wheel can do the same thing for cyclists. The way they describe how the wheel absorbs shocks claims that they are especially effective at abrupt sharp edge obstacles like riding up and down stairs. Since the rim can variably move in the direction of each impact (as opposed to a typical fork which can only telescope up and down, or a rear suspension setup which is confined to the axle path determined by its layout), it is better suited to the wide range of actual impacts your normally encounter.

When you have spent your whole life with rigid spoked wheels, they may seem strange to you at first. But we believe you’ll soon love the differences of the Loopwheel.
Each wheel reportedly weighs about 300 grams (10.5 oz) more than a comparable spoked wheel.
When you create a wheel and tire package, you qualify for free mounting, balancing, and TPMS installation.

Also, that the e-tron runs at its lowest from the factory while in efficiency mode means there are likely efficiency gains going on.
'But as soon as you ride,on a gravel road, it feels like velvet - there is no noise from the road, and it is exactly like riding a normal bike.
Each time the wheel revolves, you’re compressing “suspension”. This means that precious rider energy is being wasted, constantly. It’s kind of like the drag you get from soft, 5″ fat tires.
Still, in planes and cars, “it takes years to make changes. They have to be approved and implemented, factories have to adopt new manufacturing techniques, and so on,” said Barel. Get The Times of Israel's Daily Edition by email and never miss our top stories
A loopwheel doesn’t have the same rigidity and stiffness that’s necessary in a spoked wheel.

When Israeli farmer and entrepreneur Gilad Wolf broke his leg several years ago, being in a wheelchair didn’t stop him from venturing out to his fields and checking on crops.
Loopwheels are designed with suspension within the wheel itself: in place of rigid spokes, they have three loop-shaped springs.
Pearce is now raising production funds for his Loopwheels, on Kickstarter. A pledge of £195 (US$297) will get you a front wheel (which can be used with a conventional rear wheel), while £420 ($640) will get you a front and rear set – when and if the funding goal is met. A 26-inch model for mountain bikes is also in the works.

Need looks and performance? Coilover suspension is a great option for anyone looking to lower their center of gravity while improving overall handling. Most coilover kits offer both ride height and dampening adjustability while coming in a complete package that will replace your stock springs and shock absorbers.
Handling is similarly augmented. The e-tron’s center of gravity is already quite low thanks to the placement of the battery mass in the floor but tightening up the corners help keep it balanced.
Loopwheels come in front- and rear-specific versions, one of the key differences being that the springs in the front wheel are twice as compliant as those in the back. This is (presumably) to help keep the wheel that does the steering from being knocked and bounced around, plus it compensates for the fact that more of the rider’s weight tends to be centered over the rear wheel.
'I've now been working on making it a product for 4 years, and we've made 40 wheels and 200 springs to get it right.
Loopwheels are more comfortable than standard wheelchair wheels: they absorb tiring vibration, as well as bumps and shocks. They’re strong and durable. Loopwheels are optimised for adults. If you weigh less than 50kg, you may not feel as much benefit from the loopwheels suspension as some one heavier.

Barel sees bikers embracing the SoftWheel. “Our wheel will enable bikers to ride faster and more smoothly,” he said. “In standard wheels, about 30 percent of propulsion energy is reserved for suspension, even if that suspension isn’t necessary at a specific time. With our system, suspension can be turned on and off as needed, reserving more energy for speed.”
Less effort is needed to push over uneven pavements, cobbles, grass and gravel paths and it’s easier to get up kerbs too.
