Ride smarter, train harder.

Take your riding to the next level with the Polar M450 Bike Computer. This wireless cycling computer tracks important metrics with its accurate GPS and Bluetooth Smart compatibility. It attaches to handlebars, giving you real-time feedback of your speed, distance, current heart rate (sensor not included), and calories burned. It's compatible with Polar's Bluetooth Smart sensors for measuring heart rate, cadence, and speed, as well as Polar's Kéo Power Pedals for advanced power measurement (all sold separately).

The M450 wirelessly syncs with the Polar Flow app, giving you in-depth analysis of important physiological metrics, riding data, and route specifics on your iPhone or Android device. It plugs into a desktop PC or Mac with the included USB cable, just in case you'd like to view the Polar Flow app on a bigger display. Polar Flow integrates with Strava, sharing your latest ride with friends. Another great feature is the ability to measure your current physical condition with the orthostatic test (requires separate heart rate monitor). This test measures how your heart responds to training and factors like stress, so you can properly adjust your riding and recovery schedule.

Great value!

  • Familiarity: I've used it several times

This bike computer is easy to use, setup, pair devices; when you start a ride the GPS signal is usually found in 30 seconds, the elevation and distance calculation is pretty accurate, the mount is great, you install it super easy and it stays steady, it wont fall :).
For syncing I prefer to use the polar flow mobile app, I think it is handy, you just turn on the phone bluetooth and press the back button of your polar for 3 seconds, after some minutes your new ride will be available.
I highly recommend it, I think you get lot of features for a great value.
