So what's the alternative? Better keep your large-diameter, low-profile alloy wheel and tire set for the summer months, when the frost heaves have quit poking Buick-sized boulders through the road surface. From late October to the first of May, consider investing in a winter wheel and tire package, including steel wheels in a slightly smaller diameter than the 19-inchers that may come on your car.

Surprised at the baseless negativity this morning. Wait, no, I’m not. Maybe it’s not the simplest suspension solution, but a cool alternative when everything else is homogenizing. bazookasean on May 20th, 2016 - 9:48am
Over the winter of 2014-15, we’ve been developing and trialling our first 20 inch loopwheels designed especially for recumbent trikes. The springs are designed to cope with fast cornering and the particular forces of side-axles. We’re really happy with the results. Loopwheels-builder Graeme cycles the 12 miles to work on his trike most days – fitted with loopwheels, of course. He’s been pushing us to get these ready to share! We showed these new trike wheels at the Spezi show in Germersheim, Germany on 25 and 26 April 2015, along with another new design for trikes, with our own hubs and a disc brake fitting.

Given no e-trons yet wear a 22-inch wheel from the factory, we didn’t have a recommended factory fitment tire. However, we noticed Vossen’s own upgraded e-tron (see: Academic e-tron, p.36 Q3_2019) used 285/35R22. As it happened, this was the exact fitment that was already on these former Q7 fitted wheels. Given the 285/35R22 Toyo Proxes S/T tires were properly weight rated and that Vossen had experienced no problems, we decided to give them a try.

A Loopwheel is a wheel with integral suspension, designed for better shock-absorbing performance and greater comfort. Loopwheels give you a smoother ride. They are more comfortable than standard wheels: the carbon springs absorb tiring vibration, as well as bumps and shocks. They’re extremely strong and durable.

Richard Quest, the designer of LoopWheel, asks “Why can’t the suspension work in all directions?” in regards to conventional wheels. Hence, the idea of LoopWheel originates. A 20-inch Loopwheel with Shimano Alfine 11-speed hub weighs 2.13kg. A LoopWheel is about 300g heavier than a conventional spoke wheel of the same size. However, you do get the added suspension and a smoother ride.

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.”

The most loop-the-loops in a Hot Wheels track is 10 and was achieved by Rohan Dayal and Rahul Dayal (both India) in Mumbai, Maharashtra, India, on 7 April 2021. It took Rohan and Rahul three days to build the adjustable angle wooden platform and assemble the entire track of 10 loops over it. Two people were involved in the project. Rohan Dayal and his younger brother Rahul Dayal. "Testing was initially with few loops and as we increased the loops and the length of the track, the project became challenging. Since the track became long it needed to be supported on a firmer wooden platform. The longer the platform, the greater was the weight and bending in the center. This needed strengthening of the platform. This was the initial challenge." While testing the brothers found that the journey of the car through the loops depended greatly on the angle of the platform. To facilitate variable angles they had to construct an adjustable wooden leg support. By adjusting the leg support during testing they arrived at the best angle which gave them the breakthrough that they could achieve the target. The project cost approximately INR 3500 ( approximately £35). The cost was less as the brothers already had collections of Hot Wheels cars and track and only had to purchase the remaining missing track pieces. The plywood used for the platform was upcycled from scrap. There were a numbe rof challenges faced by the pair. As the number of loops increase, the project became challenging in terms of scale. The length of the platform, it's weight, and height also presented difficulties in handling. The speed of the Hot Wheels car increases as it descends from greater heights causing the car to lose balance. Despite all these difficulties the pair think they could attempt to increase the loops by a further one or two in the future. "Since a young age of around 12 years, I would try to do small projects like making a wooden toy car or cricket bat. Later as I grew I would do some small household repair works. For all this, I would use my Dad’s tools. As a child, I liked playing with toy cars. I would make my wooden toy car and make it slide on sloping surfaces. During this time I was gifted with Hot Wheels cars and tracks which came with super smooth cars and steep sloping tracks. Soon I had a good collection of it. Recently I came to know about the Guinness World Record of 8 loops and decided that I can better the record. The Guinness World Records titleholder would be the best thing I would have ever got. It would also mean that records are an inspiration to do better and create greater records. It would be a proud moment for both me and my family."
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

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.

They’ve also developed a more bullet-proof wheelset with 25mm of shock travel called Fluent B designed for urban bike share programs. It includes a dynamo front and an internally geared rear hub. Lastly, the Fluent E is an e-bike version with 40mm of stroke and an integrated proprietary rear hub motor.
Cohen now works as Softwheel’s product specialist, testing the Acrobat prototype as well as providing advice and guidance.
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 was happy with my purchase until this point. The bike looks nice and handled great. The only issue I noticed before this was that the left gear (I’m no bike expert, sorry if if that’s not the correct term) sort of made a weird noise when switching between one of the three settings (the chain sort of took a while to set correctly). The right gear worked flawlessly.

Quicker shift times, a tightened suspension, a 30/70 torque split and sport-tuned stability control empower TRX with the optimal performance-truck setup on paved surfaces.
Final pricing hasn’t been set, but it looks like the standard wheelset should run about $2000 when they are available sometime later this year. In each of the wheels they use tech called Adaptive Rigidity that seems to be an optimized suspension tune geared to “absorb the bumps that matter and stay rigid over the ones that don’t”. How that is achieved isn’t entirely clear, but is certainly a unique take on suspending a bike. notRapha on May 20th, 2016 - 8:06am Matt on May 20th, 2016 - 8:36am Greg on May 20th, 2016 - 8:44am
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.
For the first time ever on a Ram Truck, aluminum shift paddles are integrated within the flat-bottom steering wheel.

Big wheels and low profile tires make any vehicle look tough. For years, the aftermarket has provided wheels in the most gargantuan sizes possible, wrapping them in tires with sidewalls as thin as an o-ring. As beltlines rise, greenhouses shrink, and wheel arches become more pronounced, manufacturers are routinely shoeing their cars — even relatively sedate family sedans — with wheels 19 and even 20 inches in diameter. They look great, but their durability and expense is questionable, at best. Not long ago — well into the 2000s — most daily driver sedans came with something along the lines of a 205/60R15 tire (See this diagram to explain the numbers). Tires in these sizes typically offer a good compromise between road-holding and ride, providing a nice, fat contact patch with the road, yet allowing some flexibility in the sidewall to soak up pavement irregularities.
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
The University of Texas at Austin Center for Electromechanics (UT-CEM) has conducted a set of simulations and full-scale experiments to determine suitable shock load design requirements for in-hub (wheel) propulsion motors for hybrid and all-electric combat vehicles. The characterization of these design parameters is required due to recent advancements in suspension technology that have made it feasible to greatly increase the tempo of battle. These suspension technologies allow vehicles to traverse off-road terrains with large rms values at greater speeds. As a result, design improvements for survivability of in-hub motors must be considered. Defining the design requirements for the improved survivability of in-hub motors is the driving factor for this research.

Loopwheel springs are made from a carbon composite material, carefully developed and tested to give optimum compression and lateral stability as well as strength and durability. Specially-designed connectors attach the springs to the hub and rim. The three loops in each wheel work together as a self-correcting system. This spring system between the hub and the rim of the wheel provides suspension that constantly adjusts to uneven terrain, cushioning the rider from bumps and potholes in the road. In effect, the hub floats within the rim, adjusting constantly as shocks from an uneven road hit the rim of the wheel. The spring configuration allows the torque to be transferred smoothly between the hub and the rim.
2.1: Humps - if u roll over a hump, den the shock can make the hub offset.but if it maintain with the situation i wrote on top. then you'll have the case o rolling in a "something like a smaller wheel since the radius reduced" but will be fine, then after the humps, the wheels would recover the shape. here you'll still good
