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.
Each time the wheel revolves, you’re compressing “suspension”. This means that precious rider energy is being wasted, constantly. It’s kind of like the drag you get from soft, 5″ fat tires.
.
The big limitation that I can see, is that if there is any deflection when the rider gets on the bike, that means that the rider is essentially pedaling uphill all the time (Because he has to compress the springs as he moves forward). The other problem is that unless the springs are precisely calibrated to the riders weight this will really destroy the rolling efficiency of the bicycle. Malcolm Jacks May 23, 2020 03:09 AM
Loopwheels are designed, engineered and made in Nottinghamshire by Jelly Products Ltd. It’s a registered design with patents pending. The story of loopwheels is one of determination, and a streak of madness. They were invented and developed by Sam Pearce, in his home in Nottinghamshire, England. By training and profession, Sam is a mechanical engineer and industrial designer. By nature, he is some one who loves making things: designing, building, doing. He loves simplicity, and products that work well. Sam is practical and hands-on. He is stubborn and doesn’t give up easily. All useful traits when you find you’ve set out on a journey to reinvent the wheel.

suspension...then rims...n +40 isnt that low of an offset...anways low offset or not u can always get a camber kit n make them fit... n if u wana do it rite the 1st time...get coilovers...dont get springs...every1 who gets springs eventually get coilovers...thats bout $350 wasted rite there... i had my wheels for about a year before i had the suspension and i kept it off the car because i knew it would look terrible without the drop.

People have tried to make a wheel with suspension before but they have never had the right combination of design and materials.
Another obvious choice for marked visual and performance improvement is an upgraded set of wheels. Project e-tron came from the factory with the largest possible 21-inch wheels that were light, forged and optimized for e-tron – narrow width and rated for the higher weight of electric batteries.
A trailing arm is attached to the wheel hub at one end, and extends forward to a pivot on the frame.
With TRX-exclusive badges on the center console cover and glove box, there’s no doubt you and your passengers will always remember the name.

When you’re on uneven ground, vibrations can wear you out, making it harder to drive your chair and triggering spasms and pain. Loopwheels make travelling over bumpy ground more fun and less tiring.
Loopwheels fit most manual wheelchairs using standard quick release axles. Choose between 24″ and 25″ diameter wheels, with or without Schwalbe Marathon Plus pneumatic tyres. These wheels have a standard axle bearing diameter of ½” (12.7mm). If you need a 12mm axle bearing instead of ½” then please contact us.

The sale of Bacchetta Cycles was in the news since our last webcast. We have former CEO Mark Swanson and new owner Dana Lieberman with us for interviews. Along with the rest of the recumbent news is Honza Galla.
I was gonna make a snarky remark about damping, but if that setup provides <1.5" or so of suspension on a commuter bike, it's probably a good thing. Max on April 14th, 2013 - 5:58pm

Both modeling and experimental results demonstrate several realistic scenarios in which wheel hubs experience accelerations greater than 100g, sometimes at very low vehicle speeds. This paper focuses on the experimental determination of suitable design goals for in-hub motors (wheel motors), describing the experimental test rig, experiment procedures, and experimental results from testing conducted at UT-CEM. The paper also discusses implications of these results on wheel motor design, leading to the conclusion that a realizable and feasible design goal for a combat vehicle wheel motor shock rating is 150 g's, with a 10 to 20 ms pulse width.
Loopwheels are a British manufacturer of world-class innovation in wheel technology. The Loopwheel is a new type of suspension wheel which reduces vibration and impact on wheelchairs and bikes.
Stable PU wheel design gives the kick scooter both added stability and safety. No need for a kick stand or for unbalanced riding.
Much like their wheelchair design has made it easier and more comfortable for users to get around in an urban environment, SoftWheel hopes the Fluent wheel can do the same thing for cyclists. The way they describe how the wheel absorbs shocks claims that they are especially effective at abrupt sharp edge obstacles like riding up and down stairs. Since the rim can variably move in the direction of each impact (as opposed to a typical fork which can only telescope up and down, or a rear suspension setup which is confined to the axle path determined by its layout), it is better suited to the wide range of actual impacts your normally encounter.
It’s a good idea to schedule regular inspections of your steering and suspension systems. It is usually easier, cheaper and safer to discover and fix a problem before it snowballs, causing further consequences.

You’ll notice your loopwheel has more movement, vertically and laterally. As soon as the springs are loaded, they compress and further change their concentricity. This is what gives you wheelchair comfort and shock absorption. A Loopwheel is designed to absorb shocks, reduce jolting and cushion your body against vibration. You’ll notice more sideways movement than with a spoked wheel, but you’re trading rigidity for greater comfort. Lower Back Vibration
Design concern: Compressing the suspension changes the center of the wheel. When the wheel is also rolling this means there needs to be a ‘handoff’ between the three struts. The result will be the translation of energy in to compressing the next strut which will slow the wheel. Torquemada on May 21st, 2016 - 9:39am

I played with the idea using steel springs in wagon wheels for a Ring of Fire series fanfic (I highly recommend the books if you like time travel stories) but I am not convinced that loopwheels are a better solution than a springy seat post.

This is not to be confused with the Israeli designer Ron Arad and his Soft-Wheel invention from 2011. He’s invented, though probably not for commercial reasons, a bike wheel that will never go flat. See below.

I don’t see how they could maintain torsional stiffness under braking… And that falls into the “bad” category. Mindless on April 15th, 2013 - 12:58am Gillis on April 15th, 2013 - 1:41am
looks like the idea could be refined a bit in the direction of this Military version with an airless tire…flat proof and comfortable commuter tire would be sick. Daver on April 15th, 2013 - 5:45am Luiggi on April 15th, 2013 - 7:21am
It's a really good product my cousin loves it he is obsess with it highly recommend this product it cheap and it came in under a week

As a full time wheelchair user, I cast a very skeptical eye at said "annoyingly infomercial-style video". About the only places I have trouble are in soft gravel, sandy beaches, and deep snow. Certainly not gentle curbs and flat lawns.

Each wheel reportedly weighs about 300 grams (10.5 oz) more than a comparable spoked wheel.

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 .
The rim won’t bend or suffer from any deformation. Just the hub will move relatively to it. Ryan on April 15th, 2013 - 9:32am Nash on April 15th, 2013 - 11:00am ant1 on April 15th, 2013 - 1:29pm g on April 15th, 2013 - 11:36pm i'd like to see some comparisons on April 23rd, 2013 - 1:15pm
