How big can a bicycle be, right? Well, pretty damn big if you put a tractor tyre in it.
It took 3 months for Wouter van den Bosch, a Dutch art student to build this 1650 lb lbs (750 kg) mega-bike, but was apparently well worth it, as he became the proud owner of the biggest rideable bicycle in the world.
Apart from the tractor tyre, this giant consists of another set of smaller back wheels and is made entirely of steel.
It’s also very slow and hard to ride, as you might have assumed, since the front wheel is rather heavy, to say the least.
