Despite its nice big screen, Sigma’s new Rox 12.0 keeps weight and complexity down while being able to display and compute a host of powerful functions. The color touchscreen display—while slightly sensitive—allows the rider to easily navigate this unit’s Android OS- based system without the need for a companion app. Setup is a breeze and sensor connections are quite strong for the most part. With 8GB of internal memory (expandable via a MicroSD card), the color screen also displays navigation and maps very well. Custom alerts are a nice touch too, but the super long battery life (over 15 hours) is probably the biggest surprise.
