Your bike computer should be the last thing that you have difficulty dealing with. That's where Wahoo's ELEMNT GPS Bike Computer comes in. The device has Bluetooth 4.0 and ANT+ connectivity so its compatible with all your sensors and a companion iOS/Android app lets you set up the entire device right from your smartphone.
You've also got programmable LED indicators that you give you a quick, at-a-glance display that lets you know if you're keeping pace. You've also got built-in GPS with preloaded maps for various routes in North America, South America, and Europe, as well as a Live Tracking feature that allows you to be tracked remotely by friends or family or see fellow nearby ELEMNT riders.
