I'm not going to sleep tonight after viewing all those race 50's.

I'm getting around 100mpg @50mph on my latest 50cc, its tall geared so pickup is ordinary.

That photo above of the NSU from 56', its actually quite a large spacious body with decent height. If little panels near the bottom opened so you could put your legs out. Hell, it would work okay on the roads.

The aero 50. Easy 80mph and 140mpg. Pick it up and stack it vertically in the carpark when you get to work. Or alongside the car in the garage. Like a motorbike sneaking down the side of crawling traffic.
