Definitely not good for table tops but could do a fair wheelie .
I had one of those little beasties when I was an apprentice toolmaker and only a few years earlier had assembled them on weekends at a bike shop in the Sydney suburb of Concord. They used to pay $10 per bike and you could easily do two a day so it was good money back then.
Wonder if you could fit it with a pair of knobbies!
