As a full time wheelchair user, I cast a very skeptical eye at said "annoyingly infomercial-style video". About the only places I have trouble are in soft gravel, sandy beaches, and deep snow. Certainly not gentle curbs and flat lawns.

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.
Without a suspension system, the car’s wheels would hit a bump and move up and down perpendicular to the road surface. This vertical energy would be transferred to the car’s frame, which would pull the wheels away from the road before gravity takes over and slams the car down. The suspension system must be finely tuned using a combination of springs and shock absorbers to reduce these effects for a comfortable and smooth ride.
A loopwheel doesn’t have the same rigidity and stiffness that’s necessary in a spoked wheel.
Take the mammoth Caterpillar 797F Mining Truck (pictured above), which stands more than 25 ft (7.6 m) tall and weighs in at 1,375,000 lb (623,700 kg). Each of the big Cat's six monstrous 59/80R63 tires stands over 13 ft (4 m) tall, weighs about 12,000 lb (5,440 kg) and costs somewhere in the range of US$38,000 each.

I bought these for my two year old grandson who loves everything cars. I’m sure he’ll love them.

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 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
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.
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 played with the idea using steel springs in wagon wheels for a Ring of Fire series fanfic (I highly recommend the books if you like time travel stories) but I am not convinced that loopwheels are a better solution than a springy seat post.

Good news; the Loopwheels are already well above their Kickstarter target with 13 days still to go! They've also contacted us to say they'll be attending Naidex so we can hopefully see them then. © 2021 Created by Gordon White. Powered by Badges | Report an Issue | Terms of Service
