The Loopwheels’ spring system between the hub and the rim cushions the rider from potholes and bumps in the road. It also reduces road noise by absorbing it, thereby reducing vibration through the frame—and into the rider’s arms and body. Because the suspension is inside the wheel, you don’t need fat tires to make the ride nicer. Instead, you can use high-pressure or puncture-resistant tires.
.
Loopwheel springs are made from a carbon composite material, carefully developed and tested to give optimum compression and lateral stability as well as strength and durability. Specially-designed connectors attach the springs to the hub and rim. The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain – cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel. The spring configuration allows the torque to be transferred smoothly between the hub and the rim.
Great comments and I would like to explain the questions raised, because it is a huge innovation. Wheelchair: Nothing is rigged about it. Two of the cheapest identical Invacare wheelchairs were bought and one was modified with the Air Suspension Wheel technology. Zoltan (the inventor) has never been in a wheelchair before and therefore it may seem a bit clumsy, but definitely nothing was done intentionally. Here is the video of how it works in gravel: https://www.youtube.com/watch?v=A429IzLKbWM&t=2s.
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.

Ron Thompson is a retired mechanical engineer. He’s built a 2 wheeled bent he believes is the 4th major breakthrough in bicycle design. That’s a lofty assessment but you owe it to yourself to hear him out. The ability to recruit supplemental hand power on a recumbent bike is the intriguing innovation he’ll discuss with us today.
After coming up with the design for the loopwheel, he and wife Gemma realised that it was a risky venture and they would need to prove the product worked and manufacture it themselves to get it to market.
Pearce is now raising production funds for his Loopwheels, on Kickstarter. A pledge of £195 (US$297) will get you a front wheel (which can be used with a conventional rear wheel), while £420 ($640) will get you a front and rear set – when and if the funding goal is met. A 26-inch model for mountain bikes is also in the works.
