Considering all of the technological advances made in bicycles, cars and trains; the humble wheelchair hasn’t advanced very much since the first one was invented for King Philip II of Spain in 1595. An Israeli startup SoftWheel is about to change that with a bike and wheelchair wheel that is more comfortable and more efficient.When an unfortunate accident left Gilad Woolf with a broken leg and dependent on a wheelchair, the farmer had first hand experience of how uncomfortable wheelchairs can be for the millions of people who rely on them for everyday transportation indoors as well as outdoors.
A shock absorbing wheel has its limitations. For starters, special rims would have to pair with these spoke-shocks. Plus, the high cost of shock absorbers suggests this wheelset would be extremely expensive, and the weight of the wheel would, presumably, be much heavier than traditional wheels.

See how many cars you can race around the track before some awesome crashes happen! (Additional cars sold separately).
A pair of shock-absorbing wheels for wheelchairs with integral suspension, designed to help you push over uneven streets, rough tracks, grass and gravel paths, with less effort. The carbon leaf springs give you extra power to get up or down kerbs/curbs. They’re wonderfully comfortable over cobblestones, and potholes needn’t be a problem any more!
In deep sand and mud conditions, TRX uses a 45/55 initial torque split and calibrates both throttle management and torque distribution to mitigate wheel slip and improve traction.
The arm may be broadened into a V shape with two pivots, either side by side or with the inner pivot slightly behind the front one - a semi-trailing arm. Trailing arms are usually found at the rear only. A trailing-arm suspension on a rear-wheel-drive car. The arm is attached to the rear wheel hub and broadens into a V whose two arms extend forward to pivot on the frame. The differential is fixed to the frame and the drive shafts have universal joints.
Loopwheels have developed a robust wheel with world-class suspension that works at higher speeds, for use with power attachments. The springs utilise hi-tech carbon composite materials and are available in 2 spring strengths (Regular and Stiff), which will allow customers to get the best comfort and health protection for their weight and the typical activities that they undertake. Weighing under 3lbs (1.36kg) per wheel, and removing much more vibration than any other brand of a wheel, it is the definitive wheel if you love travelling faster on tracks and off-road. Made in England Loopwheels are vibration reducing wheels. Integral suspension gives you a smoother ride.
PU wear-resistant flash wheel, high elasticity, non-slip, abrasion resistant, quiet and smooth, no damage to the floor, durable.
One designer wants to increase shock absorption in mountain bikes by replacing standard spokes with shock-absorbing coils. Triple the shocks, triple the fun!
The twin-screw supercharger provides near instantaneous torque, has a maximum speed of 14,600 rpm and can regulate boost pressure up to an astounding 11.0 psi.

“What amazed me about Loopwheels is what an unbelievable confidence boost they gave me. They made it so much easier to get over uneven ground, and made me feel so much happier about getting out and about with my friends and family after my accident.”
A heads up to politicians and city planners: stop wasting your money on bike lanes, tax incentives, and PSA campaigns. All you need do to persuade your constituents to trade in cars for bicycles on their morning commute...
You realise in the mining truck example if their estimate of current tyre prices is out by a factor of nearly 3 (as you suggest 38k v 110k) then the whole financial justification falls apart ;) Harmen van Kamp February 2, 2018 12:30 PM
