What to look for
Decide how much data you want. Simple units show speed, distance and time — fine for fitness riders. Mid and premium GPS computers add mapping, navigation, power-meter support and training analysis (FTP, training load). Dual-band GPS improves accuracy in cities and valleys. Battery life ranges from ~12 hours to days with solar — crucial for long events. Check it pairs with your sensors (power meter, heart rate) over ANT+ and Bluetooth, and that the mount fits your bars.
- GPS & mapping: Dual-band GPS is most accurate; full mapping with turn-by-turn navigation suits explorers and tourers.
- Battery life: From ~12 hours to multiple days with solar. Match it to your longest rides and events.
- Sensor support: Ensure ANT+/Bluetooth pairing with your power meter and heart rate strap for full training data.

FAQ
Do I need a bike computer or is my phone enough?
A phone with an app works for casual rides, but a dedicated computer has far better battery life, GPS accuracy and visibility on the bars, and won't leave you stranded with a dead phone. Serious riders prefer a computer.
