Quest for transport

Straddle a tree when you climb it. Rap your legs around a giant sloth and make a long trip across the frozen ice bridge. Gallop bare back on a horse. Lean over a metal frame of tube steel and push a cushioned pad in your groin? We all love bicycle riding (or should). We are reaching a point in human interaction with the spoked wheel creature that must emulate nature. Exo skeleton crab bikes or a combination of the best mammal and insect creations. That is the question???
