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.

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.

Within 20 metres you notice how smooth the ride is, looking down and you see that its not fresh tarmac, rather it’s a country road, yet the ride gives no indication of the road surface, its just smooth – you are feeling the road rather than the grotty surface.

But the negatives are pretty significant, especially in and around Boston, where our roads are rapidly deteriorating, and potholes are a regular occurrence.
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.

Hojun Lee’s design won an award at the international design competition, K-Design. Lee currently attends the Seoul National University of Science and Technology in South Korea.
This design takes suspension to the next level and could benefit mountain bikers who want a cushier ride. Or more attention.

Vibration In Back
Do you have a trike with a rigid frame, in other words, one that is not suspended? Are you getting tired of all those nasty road irregularities knocking you around and loosening the fillings in your teeth? Had enough torture for this lifetime? Want a posh and smile-producing experience? Well then, Loopwheels may offer a solution, according to their website. Essentially, with these wheels on a rigid trike, the trike is no longer rigid, that is to say, once installed in place of traditional spoked wheels, you now have full suspension in all three corners of your triangulated realm! Cool.
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
This looks dodgy. As per above – lateral stiffness? You have what looks like three contact points spot welded to the rim. I like my rims to stay somewhat connected to the hubs. These look like they have potential for rather catastrophic failure. Bob McNaughton on April 14th, 2013 - 11:06pm

"Having the Loopwheels has been a complete life changer for me. I can now go on longer journeys with less fatigue...."
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
Loopwheels for wheelchairs help people push over uneven streets, rough tracks and gravel paths, with less effort, and the carbon springs give you extra power to get up or down kerbs. They reduce jolting and vibration, by as much as two thirds compared with a spoked wheel.

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.

Loopwheel
Copyright 2021 • SouthwestMedical.com • All rights reserved • SouthwestMedical.com, LLC Home Info _About Me _Contact Blogs _Travel _Accommodation _Days Out _Theatre _Products This has definitely been a well requested blog. I was lucky enough to get to try the only pair of Loopwheel Urban's in the world at the moment before their release later this year. I certainly put them through their paces, taking them out in the city and off-road on sand, so, I wanted to share my thoughts with you! A Loopwheel is a wheel with integral suspension, designed to reduce vibration, increase performance and provide greater comfort. Giving you a smoother ride, they are more comfortable than standard wheels: the carbon springs absorb tiring vibration, as well as bumps and shocks. They’re designed for everyday use and are strong and durable. Loopwheels are not just a wheel, they’re a suspension system. Studies have shown that wheelchair users are exposed to levels of vibration that are considered unsafe and that this can affect health and life quality. This is a risk factor for all wheelchair users, increasing the amount of muscle fatigue and potentially damaging connecting nerves. For me, vibration causes a huge increase in pain which is why I was first interested in the product. Loopwheels solved this problem by using carbon composites to create an ‘in-wheel‘ spring that can absorb vibration, without the weight penalties of a suspension chair or the cost penalties of a full carbon frame. The Loopwheels reduce vibration by 68% at 7Hz, 52% at 10Hz and 76% at 13Hz. Overall Loopwheels significantly reduce the amount of harmful whole body vibrations a wheelchair user will experience, this is turn reduces pain and fatigue and therefore allows a wheelchair user to travel further. I signed up for the 'Try Before You Buy' Scheme for the classic Loopwheels. For £20, this allows you to have the loopwheels for 21 days. This fantastic scheme enables people to see whether the product would be right for them. My loopwheels were black and fitted with ease to my manual wheelchair. I was travelling a lot when I first got my loopwheels and I found them easy to store in the car or on the plane. You can get a specially made bag to put them in if you travel a lot which I like! One thing which a number of people contacted me about is the weight of the Loopwheels. They are 1.8kg without the push rim/tyre/axle. Looking at a leading competitor, X-Core, their wheels are 1.5kg without tyres. They aren't as lightweight as I would have liked and for me, I need to take the wheels off individually and use 2 hands to lift one (I am a weakling though!). You would have to make a decision about whether you could manage the weight of the wheels independently and also if you're willing to have that extra bit of weight in return for extra comfort; it's completely individual. Short and sweet, I love the look of the classic. Wherever I go, people ask about them and I always used them for my photoshoots. Having a 'pretty' chair gives me such a confidence boost so having wheels which reflect this is so special. I have very small front castors which absorb a lot of vibration on my wheelchair. Even with the Loopwheels on, my castors at the front were still an issue. For you to get the best out of this equipment, I would thoroughly recommend using it with something like a Tri-Ride or Freewheel. This elevates the small castors and allows the weight to go through the loopwheels, giving you the best possible result. I used them a lot in the dance studios and loved the glide on the solid floor. But, because I didn't have any add-on equipment to try, I don't feel like I felt the full potential of the Loopwheels outdoors, but I still felt a difference. At £872, with payment plans available, they are certainly an investment. Other wheelchair wheels on the market cost around £250 mark, so you are looking at an extra £600. With the new personal budget for wheelchairs just released, there could be some hope that equipment like this could be provided as 'top ups' if a good enough case was made, but in the meantime, you might have to save your pennies. Have one set of wheels for all occasions – from the streets to the park to the forest. Lighter; an everyday wheel that is light enough to lift easily with one hand. Deliver all-important comfort and pain relief whilst being efficient to push and roll. Wheels that look great, and look technical – and perform brilliantly. Different spring ratings dependant on speed and weight. At 1.36 they are lighter than one of their leading competitors, X-Core, who's wheels are 1.5kg without tyres. They were much easier to lift, meaning putting them in the car and attaching them to the chair was simple. I felt a significant difference from my 'classics'. Because they were so much lighter, I could self-propel for a significantly longer time which was fantastic. I also tried the wheels out on the sand whilst I was on holiday, and despite having no add on for my front wheels, they managed really well! The wheels are designed to tackle a multitude of surfaces and they certainly excelled in that. I also like the fact there are 3 different spring ratings. Because I'm so light, I didn't feel like I was getting the full spring potential in the classic sometime but on these I can opt for the soft so I can feel more benefit. All those positive reviews do come at a price and that is £1,800. It's difficult when equipment that could potentially benefit your quality of life is so out of your price range, honestly I know, but I also have got to know the company well now and know how much they've invested so this is priced for the quality of the product. I love Loopwheels because they genuinely want to help people live better. The brand is good, the people are good and the products are good. Personally, the Loopwheel Classics didn't have as much benefit to me as I'd hoped because I didn't have a piece of equipment to lift my front castors off the ground. If you want the full potential of them, as I've said before, I'd recommend giving them a go with a Tri-Ride, Freewheel or investing in some suspension front castors. However, the Urban for me was a game changer. I really felt the benefit from these wheels, especially with them being lighter and cannot wait for their official launch so I can get my hands on them! If you'd like to learn more about Loopwheels, try or order some, visit their website https://www.loopwheels.com I am an ambassador for Loopwheels, because of my love for the product, so the wheels discussed in these reviews were either #Gifted or PR trial. But, I certainly am honest with my review of them!
I’m beginning my return and hopefully the next one doesn’t have this issue. Is there something on the user end that can cause this or is this something that was just wrong with the manufacturing? I put this bike together per the instructions. I rode it down my driveway and hit the brakes. When I did so the front tire instantly moved to the side and started rubbing the forks. I thought maybe I did something wrong so I read over the instructions and made the front wheel a little tighter. Still got the same result. Definitely going to try to return this thing. Just sucks I spent all that time putting it together and now I have to deal with shipping it back.

My background in wheel performance is its circular motion( which involves the circular of the wheel, and that the hub remains in the center of the wheel) if u are rolling with an oblong wheel, then u may actually exert more effort in lifting your self with the bike rather than rolling.

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.
Unistrut is a registered trademark or trademark of Unistrut Corporation and/or its affiliates in the United States and/or other countries.
- The suspension blocks are just over two blocks in length, making proper 1-1 alignment with the rails impossible. Their models also stick out in other places making clipping an issue.
The spring configuration allows the torque to be transferred smoothly between the hub and the rim

When you have spent your whole life with rigid spoked wheels, they may seem strange to you at first. But we believe you’ll soon love the differences of the Loopwheel.
Spotted at the Bespoked, UK’s handmade bicycle show, Loop Wheels should be getting things Kickstarter’d this week for their carbon fiber looped bike wheels. Details are pretty scant, but the obvious is the composite looped spokes that create three sets of springs between the hub and wheel.
The Loopwheel works using three heavy duty springs instead of spokes. When the rider hits a bump, the springs compress to give a smooth ride
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.
I find it difficult to credit the coach moving down the hill with 20,000 - 40,000 lbs of motorhome pressing the jack pads into the earth. That assumes the jacks are rated for the full coach weight and don't break under the load. My 36,000 lb coach had 4 x 16,000 lb jacks, so I wasn't too worried. Back in the day some coaches had poor frame rigidity, especially up front, so the front cap and windshield frame would often twist if the front wheels came off the ground. My '96 Southwind (F53 chassis) was like that and I avoided ever lifting the front to even barely touching cause the windshield would start to move. My 2002 W22 chassis coach didn't seem to have any problem with that but I was still careful. My 2004 DP was stable as a mountain no matter how much it was jacked. Spent many a summer at my brothers home in SW PA with wheels off the ground. He lives on a hill side and the 2012 Tour never had a problem.
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.
