A guy on my Island, designed and built the worlds fastest bicycle. 83 mph. Since bettered by a Dutch university team with a rider who can crank out a bit more than 1 hp.
800 watts.
Nearby everyone needs a 1/4 drag strip, and a dirt track for midgets and speedway bikes.
At the road race track, top speed is just a number. The exciting stuff is everywhere else.
But 150 plus on two wheels, every couple of minutes, is something worth talking about.
Once upon a time, about 1955, the first six seat sedan to do 100 was a Ford with the 312 T bird motor.
I put one of those engines in my 37 Ford hearse, and we topped out at about 105.
