Big wheels and low profile tires make any vehicle look tough. For years, the aftermarket has provided wheels in the most gargantuan sizes possible, wrapping them in tires with sidewalls as thin as an o-ring. As beltlines rise, greenhouses shrink, and wheel arches become more pronounced, manufacturers are routinely shoeing their cars — even relatively sedate family sedans — with wheels 19 and even 20 inches in diameter. They look great, but their durability and expense is questionable, at best. Not long ago — well into the 2000s — most daily driver sedans came with something along the lines of a 205/60R15 tire (See this diagram to explain the numbers). Tires in these sizes typically offer a good compromise between road-holding and ride, providing a nice, fat contact patch with the road, yet allowing some flexibility in the sidewall to soak up pavement irregularities.
Loopwheels are a British manufacturer of world-class innovation in wheel technology. The Loopwheel is a new type of suspension wheel which reduces vibration and impact on wheelchairs and bikes.
.
Each wheel incorporates a regular hub, with a hub brake and hub gearing. Instead of spokes, however, three looped carbon composite springs run from the hub to the rim. Whenever the wheel hits a bump in the road, the energy is absorbed by those springs.
ko2's are more like 1k. unless he puts on some P rated stock size ones. which seems silly. $800 on Amazon for C load 285's - so I was a little off. I was also assuming prices of shopping around, or else the SPC's would've been stated a bit higher. Reply With Quote 03-15-2020, 11:03 PM #5
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.”
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.

If god wanted a different wheel he wouldn’t have made them round to begin with. Louis IV was correct in closing the Patent office….all things worth being invented…were invented by the 17th century.
The latest idea to come across our desks, though, makes a compelling business case for itself as well as offering some interesting dynamic capabilities. Meet the Air Suspension Wheel (ASW), from Global Air Cylinder Wheels out of Chandler, Arizona.
Measure your peak horsepower, torque and boost pressure on any run with an integrated dynamometer. Then compare it to previous records.
The wheel fits to any bike with minor alterations. The added wheel suspension works with traditional fork suspension. Baigh explains his design in the video below. The LoopWheel is another design that features bow-spokes, only these are in elliptical shapes. The carbon composite springs isolate the rider from the high-frequency road noise preventing aches caused by jolting.

Have you ever had an oversized truck pass you and your vehicle sways from side to side? This is a sign of worn or weak shocks and struts. Weak, worn, or bad shocks and struts can cause very poor vehicle handling issues and ride comfort problems. This is because worn shocks and struts have lost the internal pressure and ability to keep applied pressure downward. This can cause excessive bounce and roll when hitting bumps or potholes, which can also lead to premature tire wear.
You’ll notice your loopwheel has more movement, vertically and laterally. As soon as the springs are loaded, they compress and further change their concentricity. This is what gives your wheelchair comfort and shock absorption. A Loopwheel is designed to absorb shocks, reduce jolting and cushion your body against vibration. You’ll notice more sideways movement than with a spoked wheel, but you’re trading rigidity for greater comfort.

Loopwheels are an innovative approach to wheelchair suspension and shock absorption.
How does it constrain the axial translation and the 3 rotations? Is is springy in all those 4 directions as well? Greg Mixson April 18, 2013 01:24 PM
A shock absorbing wheel has its limitations. For starters, special rims would have to pair with these spoke-shocks. Plus, the high cost of shock absorbers suggests this wheelset would be extremely expensive, and the weight of the wheel would, presumably, be much heavier than traditional wheels.

Second, we do A LOT of volume. This enables suppliers to rationalize giving us some of the best pricing in the industry, and once again that low price can then be passed on to our customers.
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!!

Loopwheels reduce vibration by up to 70% compared to a spoked wheel so the amount of vibration transferred into the person in the chair is significantly reduced.
In a Globe story this February, reporter Eric Moskowitz noted that Boston fills approximately 19,000 potholes in an average winter, and that the city has gone as far as developing a new app, called Street Bump, that attempts to give drivers the ability to instantly notify City Hall when a new crater appears. And that's just the city of Boston. Do the math and consider how many gaping holes have appeared in the New England region after last winter's prodigious snowfall.
Wheelchair design has evolved in recent years but users can still find it demanding to propel themselves. That can be especially difficult and uncomfortable on rough surfaces such as cobbles and paving stones.
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).
On the plus side, it's a really nice looking bike... very frustrated with it though....
Some of the most important parts of a car’s suspension system include tires, shock absorbers or struts, arms and bushings, ball joints, coil springs, and stabilizer bar link. Like most parts on the car, the shock absorbers and/or struts need to be checked regularly as part of the service schedule of the car. • Frequency of regular maintenance such as chassis lubrication and wheel alignment
Swing axles may be at the front or rear. The system is like a beam axle cut in half and attached to pivots on the frame.

The arm may be broadened into a V shape with two pivots, either side by side or with the inner pivot slightly behind the front one - a semi-trailing arm. Trailing arms are usually found at the rear only. A trailing-arm suspension on a rear-wheel-drive car. The arm is attached to the rear wheel hub and broadens into a V whose two arms extend forward to pivot on the frame. The differential is fixed to the frame and the drive shafts have universal joints.
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.
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.
It is curious as to why they put the valve stem in the middle of a loop and not between. Ham-planet on April 15th, 2013 - 3:06am
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!
