Roll Up Your Bike

Unlike existing folding bicycle designs that fold into a triangular shape, the Donut bike folds into a super-compact circle that leaves no component exposed. From the handlebars to the pedals, everything is safely tucked away and making it incredibly easy to tote around and store.

Designer: Arvind M

    Very cool bike. What do you think it will weigh? Could it be adapted to carry on your back?

  • Teto says:

    Anyway you made a good and sofisticated concept. Good job. But i dont know about driveability, the steering is to low, like a racing motorbike. The wheels are very small.

  • Arvind M says:

    In this concept the seat height can be adjusted by moving the seat support bar to different holes provided on the frame.This concept is designed for 16″ wheel size which won’t be a problem for driveability i guess.If Aluminium alloy is used then the weight would be less.
    The size of bicycle after folding: DIA26″X 6″ width.

    Same system of folding uses Locust designed 5 years ago:

    this concepts are funny to look 😉 will never work praactically … think about all parts like cable and brakes and gearshifter. and the weight will be much more then existing folding bikes also too expensive to produce,

    I like it because you would make all the idiots riding Segways look like rockstars in comparision. That’s a major accomplishment!

    Pro: the most compact folding bike I’ve seen yet.
    Holy crap. That’s awesome.
    Give it some side panels and it’ll look like a dinner plate.

    Con: riding appears very uncomfortable.
    It appears as though the designer has never ridden a bike. The handlebars are positioned lower than the seat! Anyone who rides this thing will get scoliosis!

  • Its so Good for the future, because its very flexible.. haha nice broo
