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

[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.

Hubless inline skateboard


We’ve been talking a lot about alternate modes of transportation lately. The 360 inline skateboard immediately caught our eye for its simplicity and hubless wheel design. The usage seems fairly straightforward, but the videos posted by designer [Francesco Sommacal] don’t make it look exceptionally fun; more like they’re daring you to use the thing. What we find most jarring about this is how similar it is to the Bushpig. Did the commercial gas powered version really predate this unpowered device?

The design is simple enough to understand, but we’re not really sure where you can easily source hubless wheels like this. Any ideas?
