It's A Bike Jim, But Not As We Know It

Designed for 10-15 year olds (kids get all the fun, grumble grumble), this Big Eye Cruiser bike can be adapted whenever the teen has a growth spurt, with the frame stretching horizontally.

The frame, with the comfortable-looking seat, can be angled to suit the user's height and even sex. It's a concept by Claudia Baer, Anna Wiesinger and Marlene Klausner, but actually very practical - unlike a lot of other concepts we feature on here.
