Rinky Dink

Rinky Dink is a mobile musical sound system that operates on power provided by two bicycles and solar panels. It tours the world as part of many musical festivals and parties and is an example of how green electricity can be generated and used to power things. As well as being powered by bicycle, the system itself is moved around using specially converted bicycles. It has been featured on the BBC programmes Newsnight and Panorama.

The Rinky Dink was also responsible for powering the first bicycle-powered digital recording in history—Live & Pedal-Powered (1995) by Baka Beyond.

The system was named after the expression "rinky-dink" which originally meant "rip-off", but came to mean anything that was poorly put together, amateurish, or shoddy.
