The story of loopwheels is one of determination, and a streak of madness. They were invented and developed by Sam Pearce, in his home in Nottinghamshire, England. By training and profession, Sam is a mechanical engineer and industrial designer. By nature, he is some one who loves making things: designing, building, doing. He loves simplicity, and products that work well. Sam is practical and hands-on. He is stubborn and doesn’t give up easily. All useful traits when you find you’ve set out on a journey to reinvent the wheel . . .

His point was that the general consumer market is drawn to crossovers and SUVs, and not station wagons. Contrarily, Project e-tron is enthusiast owned… and Audi enthusiasts tend to prefer Avants. The low-slung long roof of the e-tron’s body makes for a quasi-Avant profile. While the general automotive buyer **may** disagree, we think there’s something to it. Audi’s considerable history of sporting longroofs gives considerable credibility and resonates with aficionados. For us, lowering Project e-tron was always part of the plan.
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.

Loopwheels' funding campaign runs on Kickstarter through May 15, 2013. Backer packages range from a single front or rear wheel to both wheels to a Dahon folding bike pre-pimped with its own set of 3-speed Loopwheels.
Reinventing the wheel: The Loopwheels use large springs instead of spokes to give the bike wheels built in suspension

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.
Designed by Jelly Products, it’s an erstwhile standard 20-inch bicycle wheel with a twist: it comes with a suspension system built into the wheel itself. Switch them in place of your bike’s standard wheels and enjoy the most stable ride you can imagine. Or, better yet, use them for your folding bike (which, usually, skips the suspension forks to save on weight and bulk) to give it a full-fledged suspension without adding much in terms of size.

A dead axle - a rigid beam - is now used at the front on vans and trucks only. Some front-wheel-drive cars have a dead rear axle. A double-wishbone suspension. Wishbones are fitted at their outer ends to the top and bottom of the steering swivel member. The two forks of each wishbone extend inward to pivot on the frame. A tie rod - a steadying bar - is connected between the frame and the lower wishbone.
Loopwheels are an innovative approach to wheelchair suspension and shock absorption.

From their initial musings over 4 years ago to the recent debut at Bespoked Bristol, Loopwheels has been a labour of love for them.

Instead of relying on a suspension fork and rear shock, the Loopwheel lets the bike’s 20-inch wheels absorb the bumps

Daniel Barel, the CEO of SoftWheel, told the Jerusalem Post that his company’s new suspension technology is an integral part of the wheel that is selective and symmetric.
Ditto for cars, said Barel, although implementing the SoftWheel system in planes and cars won’t happen overnight. “Plane designs have to be approved by the Federal Aviation Industry in the US, and implementing changes in the automobile industry takes time. But eventually, both industries are going to adopt our design. Until now you had to choose between comfort and efficiency in wheel design, and now, for the first time, you can have both.”
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. Colour Wheelchairs

“First of all, it is symmetric to absorb shock in any direction," Rozanes told From the Grapevine. "Second, selective suspension means if you drive normally on flat surfaces, there’s no suspension unless encountering an obstacle."
The first performance-focused steering wheel on a Ram Truck boasts integrated aluminum shift paddles, a flat-bottom shape and available carbon fiber and Alcantara® suede accents—exactly what you should expect in a performance truck.
When off road, use the Vehicle Dynamics page to dial in the optimal steering angle, lock your axles and modulate your transfer case gearing.
We stock a range of other push rims, not all of which are listed here. If you’re not sure which to choose, please contact us as we’ll be happy to help.
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.

agreed..but if money is an issue, I'd grab the $100 set of springs first then get the wheels. from experience in my trans am, springs/shocks/struts/whatever made a HUGE HUGE HUGE difference. I put vette wheels on and I just got wider tires which was sweet but i noticed a BIGGER difference from springs/shocks Well, my budget only allows for one at a time, and i'm just worried if I get springs ill have to just take guesses on wheel/tire sizes. I'm very unfamiliar with this kinda stuff as it is my first go. From what I am gathering the springs i'm planning on getting lower 1.5 - 1.75 im guessing the 1.75 is after they kinda break in over time. Not sure. However, the issue is knowing what tires to go with. If I have to chose 1.5 or 1.75 which is a better option? Keep in mind i'm most likely getting 15X7wheels, seems common enough and im not big on bigger size wheels, hell, i'm rocking 13's at the moment, steelies.. but 13's either way Also, I am not the fan of the "slammed" scene. I am more so into the flush look. Deleted wheel gap but not so over the top that negative camber makes my wheels look broken So from this information hopefully I can get some guidance with a tire size for 15X7 or maybe a slightly different recommendation based on the ride height adjustment soon to come. I also may consider 16's but 15's prefered. lets B-serious here tho, suspension first or else you'll be at stock hight or bounching around on these ebay special "coils", don't cheap out on tires like I see soooo many ppl do. lets B-serious here tho, suspension first or else you'll be at stock hight or bounching around on these ebay special "coils", don't cheap out on tires like I see soooo many ppl do.

SoftWheel also claims that this movement measurably decrease the energy lost from suspension movement. Their simulated track testing equated these gains to 16.4% extra energy that was not lost in a traditional suspension system. That of course means saving energy for the rider, and results in faster rolling. We’ve seen conceptually similar solutions like the carbon leaf Loop Wheels without damping, and even a smaller amount of suspension built into Gokiso’s hubs, but these Fluent wheels are certainly more tech-heavy.

on flat ground due to the hub always being nearer the ground than the top of the wheel, all three “loops” have to flex and return for each revolution of the wheel, meaning it would be like going up a gentle hill all the time (work wise)? (unlike conventional suspension that will flex due to riders weight and stop regardless of revolutions.
