Curve & Curve L are a high quality, ergonomic push rim designed and made in Germany. These are available in two sizes: ‘Curve L’ for a larger hand, or ‘Curve’ for smaller hands. Designed for wheelchair users with complete hand function.
With any wheels there is always a little trepidation about hitting larger more inanimate objects but with Sam goading me on I started to aim for rocks, ruts and tree roots (did I mention we were riding off road!!!) and in every instance the wheels soaked up the impact, leaving me free to ride the bike without worry of knackered rims, aching arms or even getting up out of the saddle to soak up the impact – you can just let the wheels do the work.

Yeah, I think that’s definitely a neat idea. Depends on how well it works, though. And how much it weighs. And how much it costs.

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.

For wheelchairs and bicycles, adding SoftWheel suspension is all about increasing energy efficiency and making the ride much more comfortable. For the car and plane markets, the system will be able to save manufacturers a lot of money, Barel predicts. “The bigger the vehicle, the more suspension you need, and both cars and planes have elaborate suspension systems,” said Barel. “In order to make up for the energy expended on the suspension, engines have to be made to work harder, using more fuel and resources. With our sensor-based technology and the suspension system built into the wheels, you can save a lot of fuel.”
This looks dodgy. As per above – lateral stiffness? You have what looks like three contact points spot welded to the rim. I like my rims to stay somewhat connected to the hubs. These look like they have potential for rather catastrophic failure. Bob McNaughton on April 14th, 2013 - 11:06pm
On front wheels, the whole strut swivels to allow steering. Pivoted arms extend inward and forward to the frame in order to keep the wheel upright and resist accelerating and braking forces .
This causes the hub to momentarily dip down within the wheel by up to 45 millimeters, so it’s actually a bit off-center until the springs flex back into their regular state. For this reason, the wheels will only work on bikes that already have sufficient space between the fork/frame and the tire – otherwise the bike would be hitting its own tires when the springs compressed.
“I see you have constructed a new carbon fiber suspension wheel. Your skills are complete.” Luker on April 14th, 2013 - 8:37pm Brandon on April 14th, 2013 - 9:35pm ChrisC on April 14th, 2013 - 10:37pm
He started a company, Softwheel, in 2011. He found support in life sciences firm RAD BioMed Accelerator Group, based in Tel Aviv. With RAD's state-of-the-art facilities at his disposal, Wolf built a team of engineers and designers. Soon after, his product, the Acrobat, was born. The Acrobat is a shock-absorbing wheel invented by Gilad Wolf and his team at Softwheel.
