Cycling GPS computers have improved leaps and bounds in terms of functionality and battery life in recent years. As part of the VeloNews Project 14er, we test three computers to test battery life and elevation accuracy. The three computers on test, and their claimed battery lives are: Garmin Edge 830 ($399) Up to 20 hours Stages Dash L50 ($299) Over 11 hours Wahoo Elemnt Roam ($379) 17 hours Ben Delaney and Betsy Welch tested them by climbing 14,000 feet, starting from a known elevation in Idaho Springs, Colorado, and riding to the top of Mount Evans - twice. While each computer has its own pros and cons, we focus just on two things in this video: battery life and elevation accuracy. If you have any of these computers, let us know in the comments what your experience has been on battery life and elevation accuracy.
