Much better to start with the wheelchair and bicycle markets, which are easier to break into. “Most of the world’s wheelchairs are used in hospitals, but there is a large premium market for people who want to live active lives but are restricted to wheelchairs by their disabilities. These people want to be as mobile and self-reliant as possible, and our technology makes this possible,” said Barel.
2.1: Humps - if u roll over a hump, den the shock can make the hub offset.but if it maintain with the situation i wrote on top. then you'll have the case o rolling in a "something like a smaller wheel since the radius reduced" but will be fine, then after the humps, the wheels would recover the shape. here you'll still good

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.

You’ll notice your loopwheel has more movement, vertically and laterally. As soon as the springs are loaded, they compress and further change their concentricity. This is what gives your wheelchair comfort and shock absorption. A Loopwheel is designed to absorb shocks, reduce jolting and cushion your body against vibration. You’ll notice more sideways movement than with a spoked wheel, but you’re trading rigidity for greater comfort.

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
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.

The wheel fits to any bike with minor alterations. The added wheel suspension works with traditional fork suspension. Baigh explains his design in the video below. The LoopWheel is another design that features bow-spokes, only these are in elliptical shapes. The carbon composite springs isolate the rider from the high-frequency road noise preventing aches caused by jolting.

Loving this well made Schwinn! Have many miles of very hard riding on it now and it is holding up well. Zero issues and still functioning perfectly. There is a slight amount of seepage at the front forks but that is normal. I have just about worn out the tires but that is after a lot of miles, most of which were ridden on rough rocky roads with zero flats. Overall this bike is a winner. Well worth the current price.
