Karoo 2
Hammerhead Karoo 2 Review
Tested and reviewed for bikepacking use
The Karoo 2 runs a full Android OS on a high-resolution 3.2-inch color touchscreen. On-device route planning, automatic rerouting, and frequent software updates make it feel more like a smartphone than a bike computer. Supports SIM-free connectivity via WiFi for on-the-go map downloads.
Who Is the Hammerhead Karoo 2 Best For?
Tech-forward riders who want the most capable touchscreen navigation experience. If that describes your riding style, the Karoo 2 should be at the top of your shortlist. It sits in the Navigation & Electronics category alongside 7other products we've reviewed.
How It Compares
At 132g and $400, the Karoo 2 is 63g heavier than the lightest option in this category (the Wahoo ELEMNT BOLT v2 at 69g). The most budget-friendly option is the Garmin eTrex SE at $150.
The price-to-weight ratio comes in at $303 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
