If anyone\\\\\\\’s interested the wikipedia article for a freewheel gear is here – http://en.wikipedia.org/wiki/Freewheel

I did build something similar for a small college project regarding power conservation once a long time ago. Not a bicycle, but using a freewheel gear system.

Anyway, this looks rad, don\\\\\\\’t know how well it actually works though.

Looks cool but does not work.
You just can’t put pedals on a front wheel(or the it’s axis)there is to much pedal induced steer.
Now if it was on the rear wheel, then no problems,
sort of a monocycle with a front training wheel
But as said, 1:1 ratio is silly.Dose look like ~20″ wheels,
so it’ll be good for a cruising speed of 5-8km/h, so indeed, one would be better off walking ;-p
It needs gearing, at least an internally geared monocycle hub to make it work.
Or just make it a “walk-bike” http://www.youtube.com/watch?v=DO3EiOp6EQA

it looks like you have to take your feet off the pedals to steer?
what do they mean by “free wheel gear”? the sprockets on a conventional bike magnifies the pedal motion so that the wheels are spinning much faster than the pedals making it an extremely efficient form of travel. there doesn’t seem to be that here. it appears to be a 1:1 ratio between the pedaling and wheel spin so basically it’s just as effecient to walk.

This is so cool! Although I wouldn’t use the adjective cute to describe it. It’s more like cool or modern-looking. I’d buy this if I can afford it and I’ll use it whenever I can. The fact that you can pull it around like a luggage is just so awesome.
