In a Globe story this February, reporter Eric Moskowitz noted that Boston fills approximately 19,000 potholes in an average winter, and that the city has gone as far as developing a new app, called Street Bump, that attempts to give drivers the ability to instantly notify City Hall when a new crater appears. And that's just the city of Boston. Do the math and consider how many gaping holes have appeared in the New England region after last winter's prodigious snowfall.
To ensure that its product lived up to user standards, Softwheel turned to Dror Cohen, who became a paraplegic after a car accident in 1992. Cohen eventually became a decorated athlete, leading Israel to the gold medal in sailing (sonar class) in the 2004 Paralympics in Athens, Greece.

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.
Barel sees bikers embracing the SoftWheel. “Our wheel will enable bikers to ride faster and more smoothly,” he said. “In standard wheels, about 30 percent of propulsion energy is reserved for suspension, even if that suspension isn’t necessary at a specific time. With our system, suspension can be turned on and off as needed, reserving more energy for speed.”

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.
GRAND RAPIDS, Mich. — New for 2021, TerraTrike’s Rogue creates a whole new level of comfort and ease in cycling, a complete departure from the world of finicky, clunky shifting. The Rogue’s internally geared Enviolo hub offers an infinite range of seamless shifting – from a standstill or under load – without the noise of idler pulleys or the constant tuning of derailleurs.
Rear Loopwheels are about twice as stiff as front installations, and wheels can be used both separately with a spoked wheel, or as a set, plus as the lone form of bike suspension, or in addition to suspension forks. At only around 0.7 pounds heavier than spoked equivalents, Loopwheels make for particularly appealing add-ons to folding bikes, most of which don't bother with suspension systems due to the weight and bulk they pile on.
With standard quick release axles, a choice between 12mm or ½ inch bearings and available in 24″ and 25″ sizes, Loopwheels fit most manual wheelchairs.
All told, we’re very happy with the results of our suspension and wheel upgrades. Yes, the changes have affected range, so the more range anxious e-tron owner may wish to steer clear.
A Loopwheel is a wheel with integral suspension, designed to reduce vibration and increase performance and provide greater comfort.
Handling is similarly augmented. The e-tron’s center of gravity is already quite low thanks to the placement of the battery mass in the floor but tightening up the corners help keep it balanced.
2: forward- in a plane terrain riding, if your moving forward. (with the 1st case scenario considered) i think its good to.
PU wear-resistant flash wheel, high elasticity, non-slip, abrasion resistant, quiet and smooth, no damage to the floor, durable.

There are three times when you should get your steering and suspension systems inspected. Every 50,000 miles (approximately 80,000 km). As part of your annual service or any time your car is in for routine service and the steering and suspension systems are accessible. When your tyres are replaced. When your brakes are serviced. When your oil and filters are changed.
