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)
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.

Worn, weak, or bad shocks and struts can also affect your vehicle stopping distance by up to 10 feet. Furthermore, they place excessive pressure on additional suspension components such as your upper and lower ball joints, tie rod ends, and bushings.
It is a significant risk factor for those with spinal disorders, increasing the amount of muscle fatigue and potentially damaging connecting nerves. Vibration is also believed to have significant impact on pain, the development of pressure sores, spasticity and general discomfort. It limits the time, distance and surfaces that users will consider for manual chair use.
Looks great...thanks! Those are very clear, telling pics...no fear about getting 20" wheels now. I appreciate it. Not to mention the tires are significantly cheaper than 19's. What I was referring to before was a generalization with 19" wheels as opposed to your concern of having 20". When it comes to how a car looks with aftermarket wheels, it really depends on a combination of the offset, size and width. A combination of the three as compared with stock specs will either give you more positive or negative camber and therefore can change the wheel gap. Before you make your purchase, I recommend learning how the dimensions of your setup will change based on the wheels that you want. This will give you a better understanding of their affect on your wheel gap. The pics i've seen so far have been fine so I doubt there will be a huge change but nonetheless, your best bet would be finding a picture of a stock suspension car with the same sized wheels and offsets that you want.

They won a £24,000 Innovate UK grant in 2013 that helped them to develop the loopwheel for wheelchairs. A further £240,000 grant in 2017 allowed them to work with 2 companies, Strategic Simulation and Analysis (SSA) and Composite Braiding, to further develop the loopwheel to go faster and for use off road and on rough terrain.

There are a lot of good points that have been made in this thread. I think a big factor in your decision will be really the road conditions in your area. Lots of changes in slopes that cause you to bottom out would not be a good thing for a lowered vehicle. The cars I have seen here look quite good, mostly because they have either 19s or dubs on them. I'm having such a tough decision on whether or not I want to get a ZR or G coupe. Keep the pics coming...maybe it'll help persuade me one way or another.

Anyway, I originally ordered two solid honeycomb-types tires, assuming the claims of then being nearly impossible to mount were wildly overblown... of course, I was unable to mount the rear (I didn’t even attempt the front). This is a perfect replacement and the included rotor and rim appear identical to OEM.

A Loopwheel is a wheel with integral suspension, designed to reduce vibration and increase performance and provide greater comfort.
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.

It’s one thing to look at the video, but up close they really are a sight to behold – they literally challenge everything you think you know about a spoked bike wheel.
But the negatives are pretty significant, especially in and around Boston, where our roads are rapidly deteriorating, and potholes are a regular occurrence.
But after a few rocky encounters, he decided there had to be a better way to maneuver over rough terrain in a wheelchair. So he did what anyone with experience in mechanics would do – he made a new wheel.

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.
When the damper inside a MacPherson strut wears out, you can buy a replacement cartridge which — depending on type — may or may not include new parts for the strut itself.
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.

While entirely theoretical, Lee’s design is not without merit. Spokes and rims found on any standard bicycle already absorb shock, albeit minimally.
5.0 out of 5 stars Ideal rear tire-on-rim and rear rotor replacement for M365 scooter and knockoffs (e.g. GoTrax GXL) Ordered as a turn-key solution to replacing the badly worn pneumatic rear tire on a GoTrax GXL v2. They sell their own, but I won’t buy their parts and generally advise against buying one of their scooters and explicitly advise against buying direct from their website. If you’re budget constrained or just want the minimum viable product to determine whether the “balling uncontrollably on 8.5’s” life is for you, make sure you purchase through Amazon or a retailer with reasonable buyer protection and return policies.

Hi we are new to a air ride equipped motorhome and are wandering if it is ok to lift the wheels off the ground with the Jack's when leveling on those unlevel sites, the chassis is a Freightliner XC and it seems like the air bags are really stretched if the wheells and everything are pulling down on them in this situation ... We just do not want any damage to the system. Your input would be appreciated thanks The weight of the axle pulls down on the air bags but the weight of the front axle assembly is supported by the length of the shocks. When the shocks become fully extended, air bags, leaf or coil springs, that's when the front axle assembly quits moving down. I'm with everyone that doesn't like the looks of wheels in the air, but it doesn't hurt anything and I have done it. Think about this: The only way your motorcoach can roll away is if it's on the wheels. If it's up on the jacks, it can't roll. A good backhoe operator will hike the rear tires (where the brakes are) up in the air to get it up on the hydraulics where it is solid and stable, before operating. Sometimes they raise the front tires up with the bucket. Ever seen a mobile construction crane? First thing they do is raise all the tires up off the ground to get the unit level and stable before operating. I'm not saying to lift your coach that way, but it's not the big deal that some people try to make it sound like. On my Freightliner with the stiff rear end and V-Ride, if I lift one side a couple inches, the duals will come off the ground. Not a big deal because the jack won't roll.

Probably needs CX bike tyre clearances on the forks and stays while fitted with 700×23 tyres. Else the wheels/tyres will bottom out onto the frameset / fork crown on hard bumps wouldn’t it ?? Ol'shel' on May 20th, 2016 - 11:16pm

"Loopwheels are fantastic, much stronger and able to take the knocks and bumps on the roads, pavements and woods, initially a large investment but so worth the money, just buy them..."
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.
Generally, only very high-end wheelchairs have shock absorption built in, necessitating wheelchair-accessible entrances to buildings. “It’s difficult and painful to use a wheelchair to cross the street, with the chair’s rider feeling the strong impact of a chair going off the sidewalk and onto a curb,” said Barel. “With a SoftWheel-equipped chair, a wheelchair user can cross streets or go down steps without feeling the impact.”

4: Up hill- this is where i think you may encounter difficulty. since its a climb. assume that you follow case 1, then you should be at least fine here. you have to focus on the ground distance to hub must always be greater than radius of wheel parallel to inclination of climb. (because imagine case 1, if your hub is no longer at the center, you will be lifting your self. in an inclined position. more difficult than lifting in a plane.
