I rode a high wheeler once. It was crazy. I found getting on and getting moving was surprisingly easy. Staying upright was easy because of the big, heavy gyroscope. Then I came to the end of the street, a T intersection with a highway. Uh oh. I didn't know how to stop, and I was not prepared to step off the bike backwards. I ditched it to the side and jumped off. I didn't get hurt, but I never tried it again. Read Mark Twain's accounting of him trying to learn. There are many good reasons we don't ride them any more and why the replacement was called a safety bicycle.

i know you're after the interesting and stylish rather than the practical, but you should know that this is a serious undertaking. Try before you buy.
