Ordinary bikes have a riding position that's either upright or leaning forward, while recumbents have a reclining riding position, some to the point of almost putting the rider on his back. Usually they're heavier than ordinary bikes, but also offer less wind resistance. The weight and the limited ability for the rider to move his body around makes them less suited for climbs and technically challenging rides, while the lower wind resistance makes them an excellent choice for flat rides.
A bicycle wheel is considered a wheel and axle simple machine. When the wheel turns, it enables movement with reduced friction and effort. The axle acts as a fulcrum for the wheel to rotate around.

It's a wheel that uses a certain kind of rim and a certain kind of tire that lets it get away w/o using an inner tube. Main advantage is that the rider can use a lower tire pressure (which leads to better traction) w/o getting flats
