GPS units

If you're the kind of person that likes to log your miles, but you're not the kind of person that analyses their heart rate zones after every ride, then the Garmin Edge 200 is for you. It's a super-simple GPS unit that has a fairly basic data set but makes keeping track of your mileage totals a piece of cake. It's not perfect - the limited display options will put some people off - but the simplicity and swappability between bikes will ensure its popularity.

Bryton are a new player in the GPS market and their Ryder 50 is a colour unit with full UK mapping built in. It's a bit rough round the edges in terms of the software side, and feels a bit like a work in progress at times, but performance is generally good and the unit itself is solidly built and fairly easy to use.

Garmin’s new Edge 800 GPS-enabled bike computer comes packed to the rafters with the features of the existing Edge 500 and 705 models, but with a bigger display than either, touch screen operation, and faster satellite location. It’s a fantastic bit of kit.

Garmin's Edge 500 GPS computer is a little wonder for giving you all your ride information in an easy-to-use and downloadable package.

You can buy the Edge 500 with a speed/cadence senor and a heart rate strap (£249.99) or you can just go for the head unit on its own (£199.99). Used alone, it tracks your speed and distance via satellite technology and you rarely lose the signal on the road – just occasionally when you’re riding beneath overhanging trees or next to tall buildings.
