This is a video of Colin Furze replacing a bicycle's traditional frame with three heavy-duty springs. He calls it the Bicycle Of Springs. I call it the Spring Bicycle, which is way better than *putting on cool guy shades* a Bicycle Fall. "Take those off." Come on!
Keep going for the video, but skip to 8:00 and beyond if you just want to see Colin riding the finished product complete with his chain coming off multiple times due to lack of tension.
Thanks to David D and hairless, who agree he should have made it out of Slinkys instead for easy cornering.
