Default re: 60 MPH...achieveable? Who cares?!? Let blueprint an engine!

Bicycles have achieved some pretty impressive speeds, especially drafting. The current record for an upright bicycle drafting at Bonneville is 166.994mph. Admittedly the bike wasn't fighting much air drag but it was on it's own two wheels with a guy pedaling at that speed. The official record for an upright bike pedaled without drafting is 51.29mph. Considering that an athelete can't generate much more than 3/4 hp for a short time it shouldn't be hard for a 2hp engine to exceed 60mph. It will be interesting to see if it can be done on a dragstrip from a standing start.
