This is a prototype I built for Monash University’s Dept of Suatainability – an exerxise bike with varible load that feeds power back onto the mains grid!
With luck we’ll have a whole room of them soon, with a big display showing how much power everyone in the class in generating – a whole new level of feedback for the class and instructor, fundamentally changing theĀ motivation to exercise…

Wooow very nice bike
