Hackable. Open-source. Not usually phrases attached to bikes. But this is the age of Velosynth. Coming from EFFALO, a maker collective (EFFALO was chartered to synthesize, modulate, and deploy multimodal interaction environments that promote expressive feedback between humans, nature and technology)out of Portland, Velosynth is a bike gear add-on that converts multiple inputs from your cycling experience into data read by a synthesizer. As John Lennon said; "Strange days indeed."
There's an excellent short article at the synthgear website, and the velosynth preview video should be embedded below.
