Great comments and I would like to explain the questions raised, because it is a huge innovation. Wheelchair: Nothing is rigged about it. Two of the cheapest identical Invacare wheelchairs were bought and one was modified with the Air Suspension Wheel technology. Zoltan (the inventor) has never been in a wheelchair before and therefore it may seem a bit clumsy, but definitely nothing was done intentionally. Here is the video of how it works in gravel: https://www.youtube.com/watch?v=A429IzLKbWM&t=2s.

The Hot Wheels Massive Loop Mayhem set is a great gift for kids 5+ who love the thrill of stunts, racing and crashing their Hot Wheels vehicles.
A business supported by Innovate UK has designed a wheelchair with suspension that is improving the comfort of users across the globe. From: Innovate UK and UK Research and Innovation Published 21 June 2019 A £24,000 Innovate UK grant in 2013 helped them to develop the loopwheel for wheelchairs, and a further £240,000 grant in 2017 allowed them to partner with other companies.
In today’s full-suspension mountain bikes, the front and rear shocks do excellent jobs lessening those impact forces. And that helps keep riders logging miles and turning switchbacks.
Usually the half-axle is broadened into a V with front and rear pivots to keep it from twisting. Pivots allow the bar to twist, but to a limited degree so that rolling is controlled.

With all the comfort that the Loopwheels provided I was concerned about the responsiveness of the bike – but my worries were for naught, as soon as power is applied through the pedals the bike skips forward without any noticeable lag (I’m smiling just writing this)

GRAND RAPIDS, Mich. — New for 2021, TerraTrike’s Rogue creates a whole new level of comfort and ease in cycling, a complete departure from the world of finicky, clunky shifting. The Rogue’s internally geared Enviolo hub offers an infinite range of seamless shifting – from a standstill or under load – without the noise of idler pulleys or the constant tuning of derailleurs.

Personally I don't like to lift wheels off the ground with the jacks and I would never lift the drives off the ground. If it's so unlevel that the wheels would be off the ground, I'll run up on some boards first to get close, then finish leveling with the jacks. Fronts are ok. You won’t damage anything. As stated above, never the rears (drive wheels) because the parking brakes are on the rears. If you’re not comfortable with the fronts being off the ground, you can build some small ramps or wood blocks you can drive the front wheels onto. If you search for ramps on this forum you’ll find lots of examples. When an air bag RV is lifted, ONLY the axle weight is left on the ground. no matter the lift height. This is unlike a leaf or coil spring vehicle. The tires provide limited stopping. If the leveler pads are on softer ground, they will put much restriction to the RV moving sideways as the pads will be in a hole. The suspension system has no problem handing from the shocks / limit straps. It endures FAR greater stress while you are driving down the road soaking up the bumps and road heaves. All that being said, try to NOT lift the RV any further up than is required. Things inevitably break. Hydraulic lines, solenoids, seals etc. You don't want a single leg to drop on it's own which the torques the chassis. An RV up in the air is invitation to crawl underneath or store stuff under. Not good when something breaks. So, pick a more level spot or use blocks to get the rig as level as you can before lifting. Don't park on a hill and lift so that there is no chance of slipping sideways (tire and / or leveling pad friction). Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times... I don't like to lift either off the ground ever. I only use the jacks enough to level the final little bit and to not have the coach shake while moving around in it. The thread Sonic posted is great! I use 2x10s like suggested in the posted link, but took it slightly further. I didn't cut an angle, don't really need it and in the past I found that it sometimes gives them the ability to slip while driving onto them. I would post pictures but it is in the shop for engine repair and the boards are in unit. Basically I took 2x10s and cut 2 boards the longest that would fit in the bay I was storing them in (about 36 inches long). I then cut 3 more boards about 8 inches shorter (for a total of 4 boards high), so lenghts of, 12, 20, 28, 36 long. I have 2 sets in case there is a need for the rear duals to go on boards. To keep the boards from sliding when driving onto them, I bought 3 different size carriage bolts that would go through 2, 3, or 4 boards but not all the way through, just long enough to keep them stable as you drive. I then took a spade bit that was 1/8 inch larger than the bolts and drilled through all 4 boards to accommodate the bolts, i did this in the rear where they would line up even and no worry about puncturing tires if they popped up slightly. I then took a spade bit slightly larger than the bolt head, and drilled on top of the holes the thickness of the bolt head. This way they sit down flush with the boards. It works very well! For the jack pads, I couldn't use anything very thick, as if I am on level ground and I dump the air, I only have about 4 inches between the jack pad and ground. I took 2x4s, and cut them the length of 3 2x4s put next to each other. I cut 6 in total. I then laid them crossways (think the first 2 layers of Jenga) and nailed them together from both sides. These work great for leveling! When i get it back from the shop next week I will try to remember to post some pictures. Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times...
Loopwheels reduce vibrations by up to 70% compared with metal spoked wheels. Our innovative Loopwheel technology now comes with 12% extra hi tech carbon.
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

It does seem clear the Air Suspension Wheel is unlikely to take over as a car tire replacement any time soon. But its unique set of capabilities do seem to offer some compelling advantages in certain applicarions, and we look forward to seeing how things progress.
