Bike Pedals in Both Directions, Gets You to Your Destination AND Back

 

pedalbackward

[punamenon2] has built an interesting bike that moves forward regardless if it is pedaled forward or backwards! What? Yes, you read that correctly. Pedal forward or backwards and the bike goes forward. This project started off as any old cruiser with a free-wheeling rear hub. To pull off this mod a second free-wheel and sprocket had to be added to the current wheel assembly. One free-wheel and sprocket set is used when pedaling forward, the other set is used when pedaling in reverse. There is also a new chain tensioner that serves to not only keep the chain taut but also allows for the chain to change directions which ultimately allows this novel idea to work.

Pedaling at 128km/h

100mph bike

[Donhou] had a dream. To create a road bike capable of reaching 100mph (160km/h).

He damn well near did it too. The goal of this project wasn’t to set a land speed record, but more of an experiment in design, and building a really fast bike that still looks like a bicycle. In case you’re wondering though, the land speed record is currently set at 167mph by [Fred Rompelberg] who was drafting behind a dragster on the Salt Flats of Bonneville.

The bike features custom everything; a welded lightweight frame using Columbus Max tubing (to help with speed wobbles), super low handlebars for aerodynamics, and a massive 104 tooth chainring which almost scrapes the ground as you pedal. Even the rims and tires are unique — regular bicycle wheels just aren’t designed to go that fast.

We aren’t even bike nuts, but we thoroughly enjoyed the awesome 9-minute documentary on this project. Check it out after the break.
