Pronounced "thcray-per bike"

A bike with the front wheel removed, so that the fork scrapes along the ground when the bike is ridden. A bike will typically end up this way if the owner only locks the front wheel and fails to secure the frame. This mode of transport is popular among young males in the London borough of Southwark.
