With standard quick release axles, a choice between 12mm or .5 inch bearings and available in 24" and 25" sizes, Loopwheels fit most manual wheelchairs...
Why reinvent the wheel? Because sometimes it makes for a better bike. Loopwheels are a completely new type of bicycle wheel, designed with a unique built-in suspension that makes for a delightfully smooth ride. Instead of spokes, as on a traditional bicycle wheel, the Loopwheels have three loop-shaped springs that allow the wheel to absorb the vibrations and bumps most riders are accustomed to feeling.

Go where you’ve never thought possible with The Acrobat’sTM unique In-Wheel SuspensionTM. The Acrobat’sTM suspension arms absorb more impact than traditionaly suspended wheels. The shocks remain perfectly rigid over flat terrain, yet offer unparalleled cushioning to on bumpy pavement or off-road, to go up or down curbs and travel further.
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.

Leaf springs are likely to wear because they have several moving parts. They should be inspected at intervals specified by the car manufacturer, or at major service intervals - usually every 12,000 miles (20,000 km). Facebook @howacarworks Twitter @howacarworks YouTube @howacarworks
I'm looking to buy Enkei RPF1's. I am undecided if I should go with the 17 or 18 inch size for stock suspension. I am driving a coupe and have always felt the RPF1 visually looks 2 sizes smaller than they actually are, but I don't want to install coilovers yet - maybe in a few years, but not now.

With every rotation the springs will bend and absorb a amount of energy. Normally this is called “damping”. Its pretty useful in some cases. But it’s pretty unusual to damp a rotation of wheels, because this will slow down the straight moving. For Bicycles (and all other vehicles) you should mount your springs in the direction where the impact is coming from plus a additional damper to stop the bouncing of the spring.

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.
When taking on dunes, this off-road truck reduces shift times by 68%, sets its suspension on full damping and allows for moderate oversteer to impart maximum fun.
"If I had a preference," says Ina Ames, owner of Rim and Wheel Works in Waltham, "I'd avoid anything with a wheel diameter larger than 18 inches. Once you hit 18 inches, straightening becomes much more difficult. In the Greater Boston area, if you're driving cars with 19- or 20-inch wheels, you're just begging to come into my shop."
“In the past, if I wanted to go down the sidewalk or over any big bump in a regular wheelchair, I’d feel it a lot on my back, and it would really hurt. You do it a couple of times a day each day, a week, a month, a year – you’re talking about thousands of times,” Cohen told From the Grapevine. “With Acrobat, it's all absorbed into the wheel and not in the back, creating a better sensation when riding a wheelchair.”
@Michael Lau Presumably yes, since part of your energy will go into moving the hub within the wheels. But since they're springs, you'll get most of that back, so it's probably close enough to a wash to not matter much. Especially on a purely A-to-B type bike like a folder.

The added components don’t make the wheels all that much heavier, too, as each Loopwheel only weighs 300 grams more than a similar spoked equivalent. Because they use hubs and rims similar to standard wheels, they can be installed on any bicycle designed to take 20-inch wheels. Other sizes may come soon, although that will likely depend on how well the current size sells.
