“Selective suspension is the key to the mechanism because constant suspension creates loss of energy, making pushing more strenuous. Only when encountering an object does the suspension system activate, making the inside of the wheel, the hub, move and absorb most of the shock instead of the wheelchair user’s body,” she said.

The Shock wheel features multiple engraved grooves racing down each of the five wide spokes of this design. Forceful by nature, the Shock demands to be seen and belongs on a bike equally as opinionated. Be flashy and coquettish in chrome, or bold and visually striking in a platinum cut, the Shock is meant to turn heads and coax out a whistle of appreciation.

Power Wheels With Suspension

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

Hand Rim

It remains static on standard floors or smooth pavements but shifts to an active response mode when the wheel encounters obstacles. The wheel’s hub symmetrically expands or shrinks to absorb the transmitted shock.

    Full-suspension mountain bikes just don’t cut it for designer Hojun Lee. So he created a solution within the wheels. In place of standard spokes are three sets of shock absorbing coils in his concept renderings.

    According to Pearce, one of the advantages of Loopwheels is the fact that unlike a suspension fork, they can absorb shocks delivered not just from underneath or above but also from the front (as might happen when running into a curb head-on). He also admits that many other inventors have come up with designs for wheels with tangential suspension over the past hundred years or so, although he believes that today’s modern materials will allow his to work where others have proved impractical.
    There is a lot of research to show that ‘whole body vibration’ is associated with fatigue and lower back pain, increased spasticity (muscle contraction), and an increase in pressure sores and has an impact on bladder control.

    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.

    Innovative design means the wheel has a stiff structure but an element of compression. The springs within the wheel are made of a carbon composite material.
    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.
