The wheels are sixty-four inches apart at the road surface and onlytwenty-six inches apart at the top of their eight-foot diameter; racingwheelchairs also use heavily cambered wheels.
One of the most interesting differences lies in the greaterstability of the HyperBike. A conventional bicycle has the center ofgravity higher than the spinning axis of the wheels. The HyperBikepositions the rider in such a way as to put the center of gravity belowthe wheel axis.
Apparently, it is the stability and balance of weight relativeto spinning forces that has NASA interested. These factors would makethe Hyperbike a good choice for low gravity environments. TheNASA-funded Space Alliance Technology Outreach Program has investedsome capital in the development of the next model.
Bicycles in low gravity? I think I've heard that one before - don't all the prospectors on the Moon have one?
Lunocycles figure in Robert Heinlein's 1952 novel The Rolling Stones.
