a bit of Bike With Big Wheels and No Chain [Concepts]

The entire Circle, a compact city bike dreamed up by Sanghyun Jeong and Jun-tae Park for the Seoul Cycle Design Competition , has no chain and folds up for straightforward portability. I adore it ’cause it feels like a lemur.

You know, those little guys with the oversized black eyes? But getting back to the bike-the whole Circle concept folds up so it could be rolled from place to position, and while it’s certainly striking when it’s in bike mode, it might probably pass for some weird piece of recent art when it’s folded up.

The finest component of its design, though, is its chainless, free wheel gear system. Some designs have put forward some more plausible chainless designs-putting the pedals on the front wheel might make steering a bit of difficult, here-but that’s why the expression’s not ” it’s much like riding a unusual Korean prototype free wheel gear bicycle.” [ designboom ]
