A clown bicycle or clown bike is a
bicycle designed for comedic visual effect or stunt riding, typically by
circus clowns. It is sometimes called a circus bike.
Tall bike (often called an upside down bike, constructed so that the pedals, seat and handlebars are all higher than normal)
Tiny bicycle
Some clown bikes are also
fixed gear, with no
freewheeling, so that they may be pedaled either forward or backwards. Some are built very small but are otherwise relatively normal. Pedaling an extremely small bicycle is very difficult and usually much slower than walking, so there is little practical advantage to having a bicycle that will fit in one's purse or pocket.
