NOTE: Catrike lead time is now 27 weeks. You must order, with 50% down payment, any Catrike model you want by March 15 in order to have one by early Fall 2021. No order, no Catrike in 2021. We don’t like this one bit but we have no choice – 7 month back order time will put us out of business unless we have co-commitment for each Catrike ordered. Latest Developments in the Velomobile World Posted on February 3, 2021 by Larry Varney
First developed to smooth the ride of people confined to wheelchairs, Israeli-based SoftWheel has taken their in-wheels suspension concept and refined it for a wide of cyclists. By essentially isolating the bicycle rim from the hub with a set of three tunable shocks with hydraulic rebound damping, the Fluent bike wheel is said to deliver an unmatched level of comfort, while maintaining ride control and stability, and actually reducing energy lost when riding over obstacles and surface irregularities. Take a closer look at options for city and even e-bikes after the jump…

The company has set its sights on large mining operations to get things moving; a market where time is money, costs can be projected across decades and gigantic, short-run tires for enormous equipment can cost tens of thousands of dollars each.
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.
One designer wants to increase shock absorption in mountain bikes by replacing standard spokes with shock-absorbing coils. Triple the shocks, triple the fun!

Now consider the car that it replaces. The first-generation 2009 Chrysler 300C AWD was equipped with 18-inch wheels at the largest. A set of four 225/60R18 Continental ContiProContact ContiSeal tires is available from TireRack.com for $596, not including mount, balance, disposal, or alignment at your local retailer.
Bikes, both manual and electric, are another big market for SoftWheel, which employs six people and is located in the Haifa area. “With cities around the world implementing biking programs for commuter, there is a big market for more comfortable rides,” said Barel. “Our wheels can easily replace the standard ones used for bikes, and make bike commuting much more comfortable.”
The Acrobat doesn't exactly "reinvent the wheel," as the cliche goes, but it does improve upon it. Eliane Rozanes, one of the Acrobat’s engineers, said it has a built-in symmetrical and selective suspension system. In layman's terms, that means it takes the bumps so you don't have to.

The spring configuration allows the torque to be transferred smoothly between the hub and the rim
It's unclear at this point whether you'd lose any forward motion energy due to torque flex, but that can be tuned out of the system if required in any case. It's also unclear how much a pair of wheelchair-sized ASWs would cost at this point. We assume they're not cheap compared to a regular rim and tire setup. Here's some annoyingly infomercial-style video comparing regular wheelchair wheels to an ASW setup over curbs and grassy, uneven terrain.
