Take the mammoth Caterpillar 797F Mining Truck (pictured above), which stands more than 25 ft (7.6 m) tall and weighs in at 1,375,000 lb (623,700 kg). Each of the big Cat's six monstrous 59/80R63 tires stands over 13 ft (4 m) tall, weighs about 12,000 lb (5,440 kg) and costs somewhere in the range of US$38,000 each.

When driven wheels are independently suspended, the differential is fixed to the frame and drives the wheels by jointed drive shafts.
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.
Baigh's first prototype design comprised of parts purchased from Home Depot. The idea has since been patented.
Looks to me like it is a rigid rim and all the suspension takes place within the three loops of carbon inside. No worries about wheels changing shape or tires blowing off. The axle just moves off center during compression. ChrisC on April 14th, 2013 - 10:39pm ChrisC on April 14th, 2013 - 10:40pm jimmythefish on April 14th, 2013 - 11:00pm
We have made the difficult decision to postpone the 2021 Recumbent Cycle-Con. With the current surge in Covid cases, and so many unknowns about what may happen in the next two months, postponing seems like the most responsible thing to do at this point in time.

Once the 20inch wheel is in production, there are plans for a larger version for mountain bikes and even the possibility of a car version in the future.

If the SoftWheel catches on in the way Barel thinks it will, Israel will become a world center of wheel technology and production. “Nearly all the materials we use to produce our wheels are made in Israel, and we are currently building a large production facility in northern Israel to build SoftWheels,” said Barel. “This, like our product, is an innovation as well, because not too many industrial products are made in Israel. All around we are developing a new paradigm, one we believe the world will embrace.”
Suspension blocks are the quickest way to provide both, in addition to suspension and turning capabilities, but don't necessarily meet all demands. A rotor can also be used, but has a much lower maximum speed (60rpm, regardless of wheel size) for propulsion purposes - however it can also have its braking torque set to 0 to make it a free-wheeling axle.

Innovative design means the wheel has a stiff structure but an element of compression. The springs within the wheel are made of a carbon composite material.
PU wear-resistant flash wheel, high elasticity, non-slip, abrasion resistant, quiet and smooth, no damage to the floor, durable.
