Transform your iPhone or Android device into a powerful cycling computer with the Wahoo Blue SC. The Wahoo Blue SC is the world's first Bluetooth Smart (4.0) cycling sensor that tracks your cycling speed, cadence, and distance through the free Wahoo Fitness App and other top cycling apps.

The Wahoo Blue SC's exciting new odometer functionality tracks the lifetime distance of your bicycle and stores the data in the device. Whether you ride with or without your iPhone, as long as you have your Blue SC you will always know the total mileage of your bike. Using the free Wahoo Fitness Odometer App*, you can sync all your data once in range of your iOS device and see the lifetime mileage of your bike by week, month and year. Additionally, our open API allows other popular Apps, such as Cyclemeter and Strava to work with the Wahoo Blue SC.

Turn your iPhone into a cyclometer

I just replaced an ancient Cateye Micro bike computer with this Blue SC hardware. At present, I am using this product with the Cyclemeter app, which I find to be the most flexible in terms of interface customization. So far, I really like this combo. Installation was no more or less complicated than for other cyclometer/sensor installations. Wahoo provides two mounting options for the sensor pickup -- a rubber band and zip ties. At first glance, I liked the rubber band idea. Setting up the app for my new sensors was a piece of cake. The iPhone detected them right away via Bluetooth and automatically took care of the pairing. However, the setup and detection process varies from app to app, so I can't comment about how this process works for anything but Cyclemeter. I am now looking at adding the protective case and extended battery options, and maybe even another sensor and case mount for my mountain bike. I Like the idea of being able to use my phone for multiple bikes.
