Electric bikes have been around for a while now, but some people still seem unwilling to part with the cash for one, preferring to modify themselves rather than their machine.
Recently we saw a chap strap a rocket to his back to reach speeds of over 200mph on his pushbike, but now an unnamed maverick from Florida prefers a slightly more sedate ride with a propeller on his back.
The man already owned the motor, which is supposed to power a parachute, but when the frame broke he decided to put it to use somewhere else.
“I broke part of my paramotor frame and couldn’t fly but I still wanted to play with it,” he wrote. “I tried using it with a skateboard, but that ended badly… so then I jumped on my bicycle and took off!
“The bad: it shakes at high speeds (around 50MPH).
“The good: its super fun and it’s cheap on gas.”
