A stock Raleigh 20 is not a fast bicycle... the upright position and three speeds limit things a little.

After some work they can be made to go much faster... my P20 (custom) is set up for touring and I am pretty much spun out at 50 kmh with the gearing I have. The modifications to the frame and fork make it a very stable bike at speed and it will cruise at 30kmh all day (solo) and plays well in groups although people complains there is less draft behind the 20 so they don't get the same pull as I do.
