In addition to these suspension extra springs are added at the handle and below the seat which gives the rider a smooth ride.

4: Up hill- this is where i think you may encounter difficulty. since its a climb. assume that you follow case 1, then you should be at least fine here. you have to focus on the ground distance to hub must always be greater than radius of wheel parallel to inclination of climb. (because imagine case 1, if your hub is no longer at the center, you will be lifting your self. in an inclined position. more difficult than lifting in a plane.
The new company has financial backing from the RAD BioMed Accelerator group and is in collaboration with the Ziv-Av Engineering group. They are initially designing these wheels for wheelchairs, city bicycles and aircraft landing gear but the company says the technology would be used for other wheeled vehicles.
Heavy duty spring loaded casters Wheel Material:Iron core,PU wheels Size:5" x 50mm ; 6" x 50mm ; 8” x 50mm Loading Capacity:280kg ~ 350kg Bearing Type:Dual Ball Bearing
The added components don’t make the wheels all that much heavier, too, as each Loopwheel only weighs 300 grams more than a similar spoked equivalent. Because they use hubs and rims similar to standard wheels, they can be installed on any bicycle designed to take 20-inch wheels. Other sizes may come soon, although that will likely depend on how well the current size sells.
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.

It is curious as to why they put the valve stem in the middle of a loop and not between. Ham-planet on April 15th, 2013 - 3:06am

If god wanted a different wheel he wouldn’t have made them round to begin with. Louis IV was correct in closing the Patent office….all things worth being invented…were invented by the 17th century.
Design load data, where shown, is based on the ultimate strength of the connection with a safety factor of 2.5, unless otherwise noted.

The steering and suspension systems are important for both your safety and comfort when driving as they ensure a smooth ride as your car travels over bumpy roads. The two systems are usually talked about together as they are directly related to each other. However, what does each system do? When do you need to check these important systems? And, how can you tell if either system is damaged in some way?
