Neil Feather demonstrates his unusal pedal based instrument –

The Melocipede “is a bicycle-based roto-zither. It has 14 strings (strung hub to rim) and 8 (1.5v ) motors and 4 magnetic pickups. The pickups run through a mixer as the melocipede is pedaled in both directions and bouncing plucking etc.happens. It sounds alternately like a cello, calliope, operatic whimpering/laughing puppy. It also knocks down to fit in a suitcase.
