I do think that these are a great design and progresses the 'outdated' technology that has traditionally kept the wheelchair dated and in the past. Ive often thought that the wheelchair is pretty much very primitive in technology.
I know that materials have vastly improved to be lighter weight and some features have become updated but still, i have felt wheelchairs cope badly with the modern living world of steps..inclines, varied terrains, bumps, roads and kerbs..etc.
So i was pleasantly pleased to come across this wheel design and after watching the video i was impressed how effectively it helps the chair cope more comfortably . I can see how the shock absorbers actually do their job.
It's one of the most stale idioms in the book: Don't reinvent the wheel. But that didn't stop Gilad Wolf, the Israeli inventor who found that comfortably getting around in a conventional wheelchair was nearly impossible. Instead, Wolf set out to reinvent his wheelchair wheels.
Take a look
The SoftWheel's design features a rim that has three shock absorbing compression cylinders. This suspends the wheel's hub while evenly distributing mass along the chair, giving the rider the ability to easily descend stairs and overcome bumps.
I can see where these would be excellent going down stairs, but to get back up? No wheel can help! I do like the idea of these for cushioning in general. My forearm canes have shock-absorbing springs, and they are amazing! The slight loss of mechanical advantage is more than compensated by reduction of stress on my wrists, elbows, and shoulders. But for long-distance mobility, I am wondering how much loss of mechanical advantage occurs in non-rigid wheel, and if the vibration reduction makes it worthwhile. Would really like to try these...
I agree it would be interesting to see how the chair copes without the bounce wavewolf...On the vid it looks like a good speed can be picked up and at least 'bumps' should be less felt maybe?
Especially good for our issues in the spine..as many have lost the shock absorbing element in some of the discs or with fusions etc
This may be a 'blond' question but i wonder if there is a weight restriction for these tyres?

My intuition suggests that the "give" in this tire would seem to smooth the bumps, but still transfer of energy to person in chair would be substantial, so spines with disc problems or fusions, or neurological conditions like mine, would possibly be further impacted. What I was referring to is that when wheel gives, some propulsive energy is lost--is the lessening of vibration worth that, since loss of momentum means having to push more times.
As to weight restriction, that is another good question. Greater weight increases any bump effect for any wheel, because there is more to lift over the bump! So, I would have to think there is a body-weight at which these wheels would not function.
Ah yes good points about transferring the energy back to the person in the chair wavewolf..if we were a complete unit with the chair it would be ok but we are not lol does that make sense
