Australian term for bicycle, the shortened version of deadly treadly commonly associated with mountain bikes because of knobbly tread on the tires.

Deadly treadly is fondly used by owners of bikes who have to wear their cajones on a frequent basis, namely BMXers, freeriders and dirt jumpers or basically any bike that can and usually does result in death or serious injury.
