As for learning to ride a chopper, kids just don't seem to know the difference - they wobble around on the bike without a care in the world. Most kids that tried the small choppers that I made, could ride them on the first try. I guess if you're not used to a standard bicycle yet it may even be easier to master a chopper. Old dogs, new tricks, you get the idea.
