While entirely theoretical, Lee’s design is not without merit. Spokes and rims found on any standard bicycle already absorb shock, albeit minimally.
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.
Rear Loopwheels are about twice as stiff as front installations, and wheels can be used both separately with a spoked wheel, or as a set, plus as the lone form of bike suspension, or in addition to suspension forks. At only around 0.7 pounds heavier than spoked equivalents, Loopwheels make for particularly appealing add-ons to folding bikes, most of which don't bother with suspension systems due to the weight and bulk they pile on.
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.
If you don't mind...what are the full specs of your wheels/tires? I'm just wondering because I have the X model and I know the widths and everything will be slightly different and no staggering for me. I think your setup looks great considering no drop, but I don't know how it would compare to an X model with no staggering or spacers etc.
When one wheel moves up it pulls up one end of the bar and the other end pulls up the other wheel, keeping the car level.
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.
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.
A Loopwheel is a wheel with integral suspension, designed to reduce vibration and increase performance and provide greater comfort.
Double wishbones are used mostly at the front. There are two wishbones, one above the other, to keep the wheel upright as it rises and falls.
Founder Sam Pearce describes his design idea: “In 2007 my idea of a wheel with tangential suspension was born when I was sitting at Eindhoven airport waiting for a flight. I saw a mother pushing her child in a buggy. The front wheels hit a slight kerb and the child jolted forward because of the impact. I asked myself why a wheel couldn’t have suspension inside it, so it would soften an impact from any direction. I sketched the idea in my notebook, got on my flight, and didn’t think much more about it for a couple of years.”

Traditional wheelchair spokes have been replaced with a design that integrates suspension for smoother passage over uneven surfaces.

Making shock-absorbing wheels for bikes, trikes and wheelchairs, to help you go more places, more comfortably and more easily.
Final pricing hasn’t been set, but it looks like the standard wheelset should run about $2000 when they are available sometime later this year. In each of the wheels they use tech called Adaptive Rigidity that seems to be an optimized suspension tune geared to “absorb the bumps that matter and stay rigid over the ones that don’t”. How that is achieved isn’t entirely clear, but is certainly a unique take on suspending a bike. notRapha on May 20th, 2016 - 8:06am Matt on May 20th, 2016 - 8:36am Greg on May 20th, 2016 - 8:44am

@SandyEggoSi Locating Pin? Strut is slotted already and has cam bolts right? Or am I missing something? @SandyEggoSi Locating Pin? Strut is slotted already and has cam bolts right? Or am I missing something? Our cars don't come with OEM camber bolts on the lower strut mount. But Honda was nice enough to give us slots on the upper strut mount under the hood of the car in the engine bay. Here's a diagram:
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
As you can see, the fitment looks very good on the car. The wheels and tires fill out the wheel wells satisfyingly, though don’t rub in any way. Since the tires are summer fitment, we are running them only in warmer weather. Before the seasons turned, we were able to log some miles and found that the greater weight and larger contact patch with summer compound tires did take a toll on range. We’ve seen that come in at about 185-190 miles for a full charge in fall temperatures.
The forces imposed on the anti-roll bar subject it to constant twisting and flexing, which in turn put its various rubber mounting bushes under great load. The bushes gradually wear and lose their effectiveness. Over a period of years the rubber hardens and tends to crack.
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.

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 steering and suspension systems are important for both your safety and comfort when driving as they ensure a smooth ride as your car travels over bumpy roads. The two systems are usually talked about together as they are directly related to each other. However, what does each system do? When do you need to check these important systems? And, how can you tell if either system is damaged in some way?

Annual or bi-annual inspections of your steering and suspension systems should include: Inspecting your shocks for leaks, cracks or other damage; Looking for vehicle bounce, nose dives, squats or rolls; Spinning the tyres manually to see if there is any wobble, imbalance or uneven tyre wear; Checking for leakage from any of the steering components; Ensuring the tension in the power steering pump belt is correct; Bouncing the car to see if your shocks or struts are functioning correctly. Who should inspect your steering and suspension systems?

I was gonna make a snarky remark about damping, but if that setup provides <1.5" or so of suspension on a commuter bike, it's probably a good thing. Max on April 14th, 2013 - 5:58pm

On front wheels, the whole strut swivels to allow steering. Pivoted arms extend inward and forward to the frame in order to keep the wheel upright and resist accelerating and braking forces .

The front wheels must be free to pivot on their steering swivels. The driven wheels, whether front or rear, must also be free to rotate with the drive shafts .

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.

The gantry was to work by building a framework, with rails constructed from 1x1 blocks. The gantry X/Y axis arms are to traverse the rails with wheels. There would then be some pistons for the z axis, a rotor, and finally a landing gear for grabbing. All pretty straightforward stuff. On something like this, you do not want suspension on the wheels:

About 1% of the population in the developed world uses a wheelchair. We have hardly scratched the surface of that market yet. People in wheelchairs are living longer and healthier lives, they are more active at home and in the workplace, and some are using electric motors. There is a real need for loopwheels.
