The Suunto Mountain Bike POD mounts on any bike fork and transmits speed and distance data to your heart rate monitor watch as you ride. Compatible with the Suunto t3, t4, and t6, the Bike POD tells you your current and average speed, and total distance traveled. You can combine this info with heart-rate data during your post-workout analysis. It even includes a distance alarm for interval training. Suunto also included a mount to attach your watch to your handlebars.
