Polar's new M450 Bike Computer combines a front-facing LED light for safety with the standard GPS-and barometer-based features like speed, distance and altitude, plus Bluetooth Smart connectivity for peripherals such as heart-rate straps and power meters.
Polar has plans to integrate with Strava in October.
The M450 can also be set to generate training programs after a user inputs their training background and current physical condition, then completes Polar's tests.

Most cycling computers use the ANT+ wireless frequency for third-party compatibility with things like heart-rate straps or power meters. Polar uses its own Polar Bluetooth Smart frequency and its own sensors for heart rate, speed and cadence, along with Kéo Power pedal-based power meter Polar co-developed with Look. The M450, like the V650 computer we reviewed recently, has no ANT+ compatibility.
The M450 has a 'Back-to-Start' feature that will guide riders home â or back to the hotel â via GPS.
