The Wahoo Blue SC is the second in a new low-energy Bluetooth 4.0 line of fitness monitoring products, allowing users to compile data from their bikes using a combination of a smartphone app and hardware that attaches to the bike. The first product that uses Bluetooth 4.0 is the company’s Blue HR heart rate monitor that was announced last year and uses an iPhone app with the device. As the world’s first Bluetooth 4.0 wireless speed/cadence sensor, cyclists can easily monitor their performance via their iPhone 4S with a very easy set up.
You can easily pair the Blue SC device with top cycling apps lie Cyclemeter and Strava or use Wahoo’s own Fitness and Odomometer apps, while an newly-developed internal odometer can record lifetime bike mileage by week, month and year, and stores the data in the device itself. This means you can easily ride with or without your phone and the device will still track total mileage. It’s powered by a replaceable 3 volt CR2032 battery that’s said to be good for up to two years of charge-free usage, and has a total weight 1.3 ounces. You can mount it on the rear chain say of most bikes and it’s actually waterproof up to five feet. It also works wit the third-generation iPad, too and is available for $59.99.
