HEY BICYCLE is a design case study of a cycling computer controlled with a voice interface for outdoor & indoor workouts. The device records your rides and measures speed, power, climb, cadence and heart rate. It tells you when your training is effective, and how, as well as when, it’s time to take a break. Voice assistant is in the centre of the user experience. UX is the crucial part of our thinking. We designed the uncluttered system with just the right amount of information. Concept was designed by Jan Patawa & Filip ?erný for BRAINZ Disruptive.
