Wheelchair With Rims
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.

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.

And it's not like I have some high dollar customer sport chair, either. I use a "Breezy". Street price of $575. About as cheap as you an go. (https://www.quickie-wheelchairs.com/Breezy-Wheelchairs/Breezy-Lightweight-Wheelchairs/Breezy-600-Lightweight-Wheelchair/2403p) And the only modification I made was to cut grooves into the solid rubber tires.

Loopwheels fit most manual wheelchairs using standard quick release axles. Choose between 24″ and 25″ diameter wheels, with or without Schwalbe Marathon Plus pneumatic tyres. These wheels have a standard axle bearing diameter of ½” (12.7mm). If you need a 12mm axle bearing instead of ½” then please contact us.

The loopwheel was designed by company founder Sam Pearce, a product designer and mechanical engineer. The spokes have been replaced by a new interior that makes it easier to go over uneven or bumpy ground and removes vibration.

“What amazed me about Loopwheels is what an unbelievable confidence boost they gave me. They made it so much easier to get over uneven ground, and made me feel so much happier about getting out and about with my friends and family after my accident.”
You are currently viewing our boards as a guest so you have limited access to our community. Please take the time to register and you will gain a lot of great new features including; the ability to participate in discussions, network with other RV owners, see fewer ads, upload photographs, create an RV blog, send private messages and so much, much more! 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...

Much better to start with the wheelchair and bicycle markets, which are easier to break into. “Most of the world’s wheelchairs are used in hospitals, but there is a large premium market for people who want to live active lives but are restricted to wheelchairs by their disabilities. These people want to be as mobile and self-reliant as possible, and our technology makes this possible,” said Barel.

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.

The suspension effect also makes it much easier for a wheelchair user to negotiate steep curbs, both nosing down and backing up, as the suspension effect takes much of the steepness out of the exercise.
i think it depends on what your unique situation is. if there are rims you really like, buy them and work around it. plus, if your facing winter every year, you do not want to be dropped too much, you'll be sliding all over since you will have a lower center of gravity and have more of a grip demand on your tires. if you drop it three inches, now you need to stick with a really high offset, so that will limit your wheel choices. i think it works the same way no matter what you do-suspension first will limit your wheel options...wheels first will limit your suspension options. do you want to be scraping low with small wheels, or keep it practical with bigger wheels, it's your choice!!

The design most likely requires a drum or disc brake since the rim’s position would likely change too much for rim brakes. We’re thinking this could be a fun design for commuter and city bikes where aerodynamics and weight are slightly trumped by comfort, particularly where the streets are a bit rough.

Just purchased a 2nd Traxion for my wife; after she borrowed mine she had to have one. This one arrived in perfect condition via UPS. Had to fine tune the brakes and shifters but that is easy. The people here having pedal/crank problems are causing the problem themselves by installing them dry and severly over tightening them. Put a little grease on the threads and take them down to just beyond finger tight. They are threaded opposite of the crank rotation and will not back out, and if you ever need to replace them they'll come out easily without seizing or galling. Great bike for the money! 5.0 out of 5 stars MARCH 30, 2021 UPDATE, 2ND PURCHASE! By artillerybuff on February 26, 2019 The order stated 3 day shipping and it took 6 days, but more importantly FedEx delivered the box all tore up with bottom flaps wide open and the box of pedals lying on the ground outside of the main carton. The bike suffered several deep scratches that really bummed me out! I decided to live with it as I hate to send things back unless I have to. Other than that the bike is very nice at this price point and would have received 5 stars from me if it wasn't damaged, despite the slow arrival.
Both modeling and experimental results demonstrate several realistic scenarios in which wheel hubs experience accelerations greater than 100g, sometimes at very low vehicle speeds. This paper focuses on the experimental determination of suitable design goals for in-hub motors (wheel motors), describing the experimental test rig, experiment procedures, and experimental results from testing conducted at UT-CEM. The paper also discusses implications of these results on wheel motor design, leading to the conclusion that a realizable and feasible design goal for a combat vehicle wheel motor shock rating is 150 g's, with a 10 to 20 ms pulse width.
