“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."
For this reason, we fill the order as you have placed it with the assumption you will make the appropriate modifications to fit the wheel/tire combo.

Near the end of the video it shows the bike on the "rolling road" test bed, the rim is moving laterally, not good in most bike applications. wle April 18, 2013 05:17 PM
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
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.
People have tried to make a wheel with suspension before but they have never had the right combination of design and materials.
However, this design pushes past the norms of mountain bike suspension — and design — and has us excited to see what could arise.
To ensure that its product lived up to user standards, Softwheel turned to Dror Cohen, who became a paraplegic after a car accident in 1992. Cohen eventually became a decorated athlete, leading Israel to the gold medal in sailing (sonar class) in the 2004 Paralympics in Athens, Greece.

unlike other bikes I purchased, I did not have to make any tuning/adjustments for the deralleurs - hope this won't jinx it. The bike arrived very fast and only a little assembly to do and very easy. The gears change very smoothly. It's a little heavy but I'm very satisfied !!! Had bike for just over a month and gears don’t work proper and back wheel frame is bent and has a wobble. Thought getting a more expensive bike would be more durable but I was wrong. My 200 dollar Canadian Tire bike was better. The tires are missing some ball bearing and trying to put the tire on only results in a wobbly tire. Off to buy some ball bearings now... Grumble.
This was clearly made by someone who has never had to get two carburetors to work simultaneously or two flutists.
Have you owned this car from day 1? because that's definitely not sitting at the stock height. lol.

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.
The British engineer who really HAS reinvented the wheel: Loopwheels system abandons spokes for springs to give a smoother ride
Kerbs are less of an obstacle with loopwheels. Loopwheels reduce jolting, soften the impact of landing, and so can help manage pain. Over 95% of the customers rate Loopwheels as high or very high quality Over 85% of the users felt positive about Loopwheels after using them for 2 weeks Over 80% of our customers said they’d chosen Loopwheels to reduce the amount of vibration they experienced in their wheelchair
