Some Yale engineering students created a "spoke-less" bicycle for a class recently. I thought it was pretty cool.

The bicycle has been constantly improved since its invention and will continue to be improved for a long, long time. For example, engineers and scientists are able to create new alloys that are lighter and stronger than previous iterations.

It could have a compartment for beef jerky.
