Trackstander?

Stood up, sat down, one-handed and no-handed.

Right would be more logical in the UK - the camber of the road makes balance easier. In fact the same is true of the track too.

Right = regular
Left = qoofy

Might try it switch sometime...

The opposite from Skating/Surfing/Snowboarding then.

I'm a Goofy snowboarder (but ride switch) and a Regular Trackstander . . . go figure!
