“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.
ew springs without shocks, what good is that? and shocks, they slow you down a lot when you dont; need them ew again just something else to cost more, add weight and subtract speed no thanks plus when you stop the bike will dive Michael Crumpton April 18, 2013 05:18 PM

And it's not like I have some high dollar customer sport chair, either. I use a "Breezy". Street price of $575. About as cheap as you an go. (https://www.quickie-wheelchairs.com/Breezy-Wheelchairs/Breezy-Lightweight-Wheelchairs/Breezy-600-Lightweight-Wheelchair/2403p) And the only modification I made was to cut grooves into the solid rubber tires. (They come smooth as a babies butt. That REALLY doesn't work in snow.) Grunchy January 31, 2018 01:30 AM Reason January 31, 2018 05:28 AM
It may work fine but high volume tyres can do a very similar job while being simpler lighter and cheaper… Speshy on May 20th, 2016 - 3:38pm Ventruck. on May 20th, 2016 - 4:20pm
SoftWheel also claims that this movement measurably decrease the energy lost from suspension movement. Their simulated track testing equated these gains to 16.4% extra energy that was not lost in a traditional suspension system. That of course means saving energy for the rider, and results in faster rolling. We’ve seen conceptually similar solutions like the carbon leaf Loop Wheels without damping, and even a smaller amount of suspension built into Gokiso’s hubs, but these Fluent wheels are certainly more tech-heavy.
When I first saw the notice about this company and its products, I thought: who can resist such things? Many of the bicyclists that I know, want to share the joy of their hobby/obsession, sometimes by wearing t-shirts or jerseys with logos on them. Now, they can do that with vinyl decals that they can apply in so many places! So, I got in touch with the company to find out more about their products.

It will never be perfect, there will always be slight compromise. Now, we have three to contend with. Tony on May 21st, 2016 - 1:24am
Loopwheels reduce the level of vibration—“road noise”—through the chair frame and up into the arms, wrists and shoulders.
How does it constrain the axial translation and the 3 rotations? Is is springy in all those 4 directions as well? Greg Mixson April 18, 2013 01:24 PM
The new company has financial backing from the RAD BioMed Accelerator group and is in collaboration with the Ziv-Av Engineering group. They are initially designing these wheels for wheelchairs, city bicycles and aircraft landing gear but the company says the technology would be used for other wheeled vehicles.
In the 20 minutes I was riding them, I had a blast. It really was as simple as that, they where a real hoot to ride.
"If I had a preference," says Ina Ames, owner of Rim and Wheel Works in Waltham, "I'd avoid anything with a wheel diameter larger than 18 inches. Once you hit 18 inches, straightening becomes much more difficult. In the Greater Boston area, if you're driving cars with 19- or 20-inch wheels, you're just begging to come into my shop."
