Is the Sigma ROX 11.1 EVO worth it?

At $177.99 at Walmart as of November 3, 2026, it is a solid value for riders who want long battery life, elevation data, and sensor support without paying for a full mapping unit. Skip it if turn-by-turn mapping is your priority.

Does it have a touchscreen?

No. It uses five physical buttons, which are easier to use with gloves and in wet weather.

How long does the battery last?

Sigma claims up to 100 hours, though real-world life drops with navigation and sensor use. Most riders charge it weekly or less.

Can it navigate routes?

Yes, through Track navigation and komoot. It shows a route line rather than full street maps, so it suits planned rides better than on-the-fly routing.

Does it work with e-bikes and smart trainers?

Yes. It supports ANT+ and Bluetooth, including e-bike and smart trainer compatibility.

The computer, a mount, and a charging cable. Sensors are not included and must be bought separately.
