- Reviewed in the United Kingdom on 19 March 2016Bought after looking at Garmin edge 25 and Polar M450. The reasons I went with this was 1) longer battery life, 2) std micro usb charging (the Garmin is non std) and 3) the fitness tests that are included. I have used it now for more than 2 months.
The GPS performance, mounting and pc or mobile connection are said to be very good and I have found them to be excellent. I have linked both the heartrate monitor and the Wahoo RPM cadence unit without issue.
The data links with strava flawlessly. The polar flow portal is excellent in its own right as is the mobile version.
I have used it for running and again no issues and I am very pleased.
It cost 122 incl the heartrate monitor and the prices will drop I am sure.
It is a genuine 5 star product
- Reviewed in the United Kingdom on 24 March 2017Excellent piece of kit - does exactly what I wanted - I have used it several times in South West Scotland, Staffordshire and Forest of Dean area's and the GPS has picked up location easily everytime. HRM works well and seems accurate - Had a little problem getting it to pair but Googled this and followed advice to just removed the battery from HRM and replace it and it then paired straight away - Not a techy so no idea why this worked, but it did and no issues since. Good clear readings from the unit itself and so far good battery life - one charge seems to last about a week and this would include two or three rides of about 14km each ride. The Online Flow software is very good allowing you to plot maps of your route as well as storing readings for Heart rates during a ride, speeds achieved, total distance tarvelled and so on. I don't find the HRM strap uncomfortable to wear. Overall very pleased with it.
- Reviewed in the United Kingdom on 13 April 2016Nice simple bike computer. does the job. Just don't waste your money on the Sensors, they don't last long.
- Reviewed in the United Kingdom on 6 July 2016Excellent computer. No messing about setting wheel diameters or making sure sensors are in the correct place. Just fixt the attachment onto your stem or bars, click the computer on and ride away. Excellent bit of kit and all the info I need, and also the ability to transfer from Polar flow to Strava. Fantastic product
- Reviewed in the United Kingdom on 6 April 2016Great cycle computer for the money, has GPS and does everything it says on the tin. The only niggle I have is there is no way to "British" the unit measurements. Meaning if I want my height and weight in kg/cm then I have to have my speed and distance in Kph/km rather than mph/miles
The integration with the iOS/Android app is great as there is no need to connect to a PC to sync your ride to the online service. Just open the Polar app and hold the back button on the M450 and it will automatically upload your data while you are cleaning and packing away your cycling kit. The online app also syncs with Strava so once it is logged with Polar flow it is also logged automatically on Strava.
- Reviewed in the United Kingdom on 12 November 2015Great product easy to set up and to understand. Easy to set up and use as head unit for Stages power crank
- Reviewed in the United Kingdom on 15 October 2016Very good haven't got cadence yet heard some bad reviews about battery life
- Reviewed in the United Kingdom on 9 July 2016The Polar M450 have Polar's Coach software built in, so you dont get bogged down with data when you come back from a ride. This I have found REALLY useful. In addition, the latest firmware now allows you do to many other sports, including rowing, making this a very good value device.
However, one thing I did NOT like about the device, is that I found the buttons on the unit to be VERY annoying to use.
Other than that, an easy 4/5. If you are interested in the full review it is available on this link:

Peter KarasReviewed in Germany on 22 April 2017
5.0 out of 5 stars Geniales Gerät!
Der M450 bietet genau was ich gesucht habe und wirklich brauche. Pulsfrequenz, Kalorienverbrauch, Geschwindigkeit, Distanz und Höhenmessung über GPS, also unabhängig von Sensoren die die Radumdrehungen messen und unabhängig von den sehr ungenauen barometrischen Höhenmessern. Dadurch wird das Gerät sehr vielseitig:
es kann für mehrere Räder verwendet werden und es funktioniert auch für Wanderungen und Bergtouren.
Die aktuelle Geschwindigkeitsanzeige ist ein bißchen träge und hinkt oft ein wenig nach, aber die zurückgelegte Distanz ist dafür top genau und die Durchschnittsgeschwindigkeit ebenfalls.
Wirklich hilfreich auch die Datenspeicherung über polar.flow.com wo alle Touren auf einem Kalender gespeichert sind. Dort kann man die Tour auf der Karte nachvollziehen, Geschwindigkeit, Puls und Höhenmeter sind graphisch dargestellt. Übersichtlich gemacht, selbsterklärend und eine wertvolle Dokumentation.
Alles in allem, wer seinen Radcomputer vielseitig nützen will, wird derzeit nichts besseres finden.

5.0 out of 5 stars Excelente ciclocomputador
El aparato en cuestión llego antes de lo anunciado.
El producto es de calidad. Soy aficionado al ciclismo de montaña y recien al de ruta, y este aparato me ha caído de lujo para conocer las distancias recorridas, la duración y la frecuencia cardíaca.
Respecto a lo anterior, esta se muestra en tiempo real e inclusive el aparato te muestra el porcentaje de dicho parametro y lo divide en 5 fases que resultan utiles para diferenciar de un simple calentamiento hasta un entrenamiento severo.
Incluye obviamente el pulsometro, se ajusta perfecto a la potencia de las bicis y ademas tiene un tamaño perfecto (reducido y mas comodo que el modelo v650).
Se puede sincronizar con el iphone o una comou, para efectos de dar seguimiento a las rutinas.
Recomendable totalmente. Saludos

UmHReviewed in France on 27 September 2017
5.0 out of 5 stars Compact et performant
Ce compteur GPS Polar, est plus compact que le M650 de la même marque en proposant des fonctionalités de bases de qualité (vitesse, distance, dénivelé, cardio...Etc). A noter qu’il est compatible avec des apps externes comme Strava et qu’il n’est pas nécessaire forcément d’acheter un capteur de vitesse en plus le signal GPS permettant le plus souvent de communiquer la vitessse...etc. Je recommande les yeux fermés.

5.0 out of 5 stars Pedazo de pulsómetro
Tras dos semanas de uso todo lo que puedo decir de él es positivo. Aparte de que la estética es inmejorable, el funcionamiento lo es aún mas.
Características que destaco:
A pesar de lo ajustado de la pantalla, los valores se ven perfectamente
La facilidad para sincronizar con la app Polar Flow para luego ver el entreno en la misma app o en la web
Posibilidad de colocar los datos de la pantalla a tu antojo.
Rapidez de actualización de los valores en pantalla (1 seg)
Sencillez de manejo, como siempre, muy intuitivo.
A mejorar o añadir:
La compatibilidad con Strava, (la cual dice Polar estará a finales de año) aunque se puede hacer de forma manual.
La falta de un soporte avanzado para la bicicleta como hacen otras marcas.

5.0 out of 5 stars Super bello
Ho.acquistato questo prodotto indeciso con il Polar v650 e il Garmin.alla fine ho scelto il Polar v450 perché piccolo,economico,funzionale alle mie esigenze,pratico semplice da utilizzare e stiloso.lo consiglio vivamente.trova il segnale GPS rapidamente e si collega a strava facilmente.la.batteria almeno per le prime uscite tiene bene,dopo 6 ore di allenamento ero arrivato a metà. Da migliorare gli or per il fissaggio al manubrio
