Software

Forge Your Own Path With Route Building

Quickly upload routes from 3rd party apps via the Hammerhead web dashboard, or build your own with a couple of taps. Once you've set your route you can quickly add custom points of interest and download it for use on other devices.

See The Road Ahead With Best-In-Class Navigation

Cycling-specific navigation designed to help you never miss a turn. But with instant automatic rerouting, we've got you covered if you do.

With Beeper Notifications

Beeper alerts notify you of turns, approaching traffic, training milestones, low battery and smartphone notifications.

Conquer The Cols With CLIMBER

Our unique CLIMBER feature auto-detects upcoming climbs — even when you're not on pre-planned routes — and provides rich gradient insights so you can strategetically pace your ascent.

See What Matters With Fully Customizable UI

Choose the data you want to see, and how you want to see it. Profile-based settings make switching between riding styles easier and more powerful than ever.

Optimize Your Ride With Data Made Beautiful

We translate in-ride data into beautiful heart rate, power elevation, and gear shifting data visualizations for real-time optimization.

Stay On Top Of What Matters With Smartphone Notifications

Receive notifications for incoming phone calls and text messages, so you don't miss anything important on your ride. Or leave your phone at home. We know sometimes you just want to enjoy your ride; the K2 doesn't require a phone for you to see the road ahead.
