Hammerhead Karoo 2 GPS Bike Computer Features

Design and Display

The compact Karoo 2 features a high-resolution and responsive 3.2" color display made of scratch-resistant Dragontrail glass. Thanks to the anti-reflective coating, the maps and data are easily visible from different viewing angles.


The included handlebar mount is designed specifically for the Karoo 2. The bike computer is simply pushed into the mount from above, eliminating the need to turn it sideways as with other mounts. The GPS bike computer is thus much closer to the stem.


Setup is straightforward and almost intuitive. The Karoo2 is set up directly on the device and does not require any companion apps.


When you turn on the Karoo 2, you can select the type of ride or workout you want to do. You can customize each workout type or create new profiles. Via WiFi, you can automatically sync ride data with third-party services like Strava or Komoot. Without a SIM card, you can pair the device with your smartphone via Bluetooth. As long as the smartphone is nearby, SMS and other push notifications are displayed on the bike computer.

Battery life

You can fast charge your Karoo 2 via a USB-C port. With standard use, you'll get up to 12 hours of battery life.
