The big limitation that I can see, is that if there is any deflection when the rider gets on the bike, that means that the rider is essentially pedaling uphill all the time (Because he has to compress the springs as he moves forward). The other problem is that unless the springs are precisely calibrated to the riders weight this will really destroy the rolling efficiency of the bicycle. Malcolm Jacks May 23, 2020 03:09 AM
The Loopwheels will go on sale in September for £600, and their inventor claims they can make riding on a bumpy road 'like riding on velvet' 44 year old Nottingham mechanical engineer Sam Pearce told MailOnline he came up with idea while watching a mother try and push a child in a buggy up a kerb.

Like a regular pneumatic tire, the ASW is air-suspended, but in this case, it's not by an inflated tube. It's a full hub and wheel replacement that separates the outer tread and rim from the hub using a set of eccentrically mounted, pneumatic air cylinders.

It is a torsion bar crossing the car through two pivots on opposite sides of the frame.
Leaf springs are likely to wear because they have several moving parts. They should be inspected at intervals specified by the car manufacturer, or at major service intervals - usually every 12,000 miles (20,000 km). Facebook @howacarworks Twitter @howacarworks YouTube @howacarworks

Less effort is needed to push over uneven pavements, cobbles, grass and gravel paths and it’s easier to get up kerbs too.
There are two basic types of vehicle suspensions: independent and solid axel. The main difference between these two is that both right and left wheels attached to the same beam i.e. solid axle, while independent suspensions make provision for one wheel to go up or down without affecting the other wheel.

Yeah, I think that’s definitely a neat idea. Depends on how well it works, though. And how much it weighs. And how much it costs.

A leading arm , used only at the front, is the opposite of a trailing arm, with the wheel in front of the pivot.
If the SoftWheel catches on in the way Barel thinks it will, Israel will become a world center of wheel technology and production. “Nearly all the materials we use to produce our wheels are made in Israel, and we are currently building a large production facility in northern Israel to build SoftWheels,” said Barel. “This, like our product, is an innovation as well, because not too many industrial products are made in Israel. All around we are developing a new paradigm, one we believe the world will embrace.”

When it came time for an upgrade, we wanted to stick with the OEM look of an Audi factory wheel. So, we went with the 22-inch 5-V Spoke Star design wheel in titanium finish from the SQ7. It is a handsome design from Audi Sport that first appeared on the last-generation RS 6 Avant and the titanium finish of the SQ7 application matched the titanium accents on the e-tron.

A trailing arm is attached to the wheel hub at one end, and extends forward to a pivot on the frame.
Innovative design means the wheel has a stiff structure but an element of compression. The springs within the wheel are made of a carbon composite material.
If you want the most functionality and lowest possible clearance, check out an air ride kit. This is one of the most sought after modifications in the lowered car community. Air suspension systems allow you to dial in your fitment perfectly and raise or lower the car from the push of a button. Air suspension kits use air pressure to adjust the height of your car on command. Speed bumps are no longer a problem!
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.

i will have pics shortly, havn't put everything on permanantly yet, waiting a couple more weeks til spring. i have the wheels & suspension sitting in my house staring at me everyday, it's painful. but if you open this link, you will see 19x8 +40 lowered 1.5", just for reference. and honestly, i'm afraid to post pics on this site with the way people pick things apart, but i probably will anyway-give me a few weeks!! https://acurazine.com/forums/2g-tl-photograph-gallery-99/some-quick-sneak-peek-pics-my-03-tl-s-759701/
Loopwheels fit most manual wheelchairs. Choose spoke colour, sticker colour on black wheels, add tyres and pushrim type.
'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.

The only other way to get wheels to turn is either roll them freely unbound to anything, or attach them to a rotor. You can adjust the suspension settings to make them ridged, and you can use vertically oriented suspensions to prevent side wobble as if it was on rails.
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.
Bicycle wheels often follow a standard convention. They contain metal rods known as spokes that radiate from a center hub. The spokes provide strength in all directions as the force of the rider bears down on the wheel. The design of spoke wheels hasn't changed much in the past, but Chet Baigh has a new approach.
Have you owned this car from day 1? because that's definitely not sitting at the stock height. lol.
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!
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.

His point was that the general consumer market is drawn to crossovers and SUVs, and not station wagons. Contrarily, Project e-tron is enthusiast owned… and Audi enthusiasts tend to prefer Avants. The low-slung long roof of the e-tron’s body makes for a quasi-Avant profile. While the general automotive buyer **may** disagree, we think there’s something to it. Audi’s considerable history of sporting longroofs gives considerable credibility and resonates with aficionados. For us, lowering Project e-tron was always part of the plan.
