Not all drivers are smart and so it helps to have a smart bike. The Vanhawks Valour, a carbon fiber Bluetooth-connected bike, has sonar sensors that detect when a car has come into the cycler’s blind spot. When that happens, it delivers a vibration to the handlebars, warning the rider that a car may be encroaching on your personal ride bubble. Other sensors measure speed, distance and calories burned, and riders can use a smartphone app to track the data.
