B’Twin’s GPS unit is bulky and wobbly but offers tons of data at a great price. Simple, fast set-up gets you into essential data displayed in big, easy-read digits with a backlight for night ops. It’ll sync with B’Twin’s discount ANT+ speed/cadence (£17) and HR straps (£30) for full bike and biometric data too.
You can study sessions and download routes for the directional arrow/distance-to-next-turn function via the user friendly myGeonaute site and updated software has made Strava uploads a lot easier. Rechargeable battery life is good too, and Decathlon has a great customer support reputation if you have problems. The only irritation is that the rubber strap mount can’t be tightened enough to stop it wobbling on rough trails. It’s a bargain if you can cope with that though.
