What makes my heart go pitty-pat is the swarm of data that the sensor in the wheel captures and transmits. Not only does it track info about the biker (riding time, effort, calories) but it also grabs info from the environment, like temperature, carbon monoxide, noise and humidity. You can share this info with friends, and also with your city by making an anonymous donation of your data. The end result? A community of data-contributors helping cities build more accurate models of routes, noise, carbon emissions and temperature. All this data can be used inform urban planning, transit systems and environmental policies in service to sustainable cities.
