Power meters are the most useful training number in cycling and also the most annoying thing to own, because each one belongs to a single bike and moving it means changing cranks or pedals. CycloWatt mounts at the cleat and measures what your foot is actually doing, which means the same unit transfers between bikes in seconds — one meter for the race bike, the winter bike and the trainer. It removes the two reasons people skip power, cost per bike and installation, and the campaign cleared roughly five times its funding goal before closing in March.
