This vintage steam motorcycle prototype was built in 1836 by English railway engineers George Stephenson (father) and Robert Stephenson (son), who also built the Rocket locomotive. To us, it looks greater than many concept bikes we see today, but it seems it was a little too much for times in which the forms of self transportation consisted in either walking
or riding a horse.
After being discovered in an old abandoned workshop in the north of England, the steam prototype meant to be originally ridden on railroads is now called the Rocket Bike.
P.S. Is it just me or this thing looks a little too similar to the Triumph Rocket III ?
