Sure, you can turn your smartphone into a bike computer, but if you'd rather not put your pricey piece of tech anywhere near harm's way, Wahoo Fitness' RFLKT Bike Computer offers an alternative. Instead of packing all the brains, the device sits atop a bicycle's handlebar and displays data it's fed via Bluetooth 4.0 from cycling apps running on an iPhone 4S or 5. At launch, the hardware will support the firm's own Cyclemeter application and Wahoo Fitness App which can monitor ride information ranging from location to speed, in addition to heart rate with additional accoutrement. Aspiring Alberto Contadors can page through data and even sift through tunes on their playlist with the help of buttons on the device's side. Gently tipping the scales at 2 ounces, the RFLKT measures up at 2.4- x 1.6 x 0.5-inches and boats a one-year battery life on a single coin cell. Wahoo's gadget is slated for a December launch, but there's still no word on pricing. For more specifics, take a gander at the full press release below.
