If you’re looking for a cheap and cheerful bike computer that will track your ride time and speed, there are lots to choose from that will do just that.

The sophistication of the technology used in the computer will depend on how much you spend. For £20 you’ll get a simple but useful wireless bike computer that will track basic ride data as ride distance and duration, and display it on a backlit screen. 

Add another tenner and you’ll get a computer that connects to your smartphone

Above £50 and you’ll start to find more sophisticated bike computers that track physiological elements such as heart rate, plus bring you weather conditions, GPS navigation and live route updates. 

Most bike computers now come with their own apps and will link to Strava and other third-party apps for extra performance comparison.

Less is more with the B’Twin 100 Wired cycling computer.

It’s old-school tech but if you are an occasional cyclist, this compact computer has five functions that will tell you your current and average speed, ride and total distance, as well as the time.  

It’s claimed to be watertight, and uses three buttons to operate it making it a simple and durable little cyclometer.

The Giant Axact is a nine-function analogue bike computer for under £20 that’s controlled by one simple button, making it easy for when you’ve got one eye on the traffic and one on your route.

It will attempt to work out your calorie consumption along with max speed and riding time while tracking your distance. So, if you’re looking for a step up from a wired option, Giant has got you covered. 

 B’Twin 500 Wireless Cyclometer

For under £20 the B’Twin 500 has all the basic measurement features you’d hope for, including speed and distance plus temperature info. 

Navigation is a forfeit here, but the B’Twin is a simple piece of tech with a backlit screen that’s controlled via three buttons. Less is more, some say.  

Unexpectedly, it comes with a magnet-free gyroscope sensor for attaching to your wheel hubs on flat ground, which is great for turbo training, but isn’t suitable for use over rough terrain.

If you want a wireless cycling computer you can use on two bikes, a 2-in-1 system means the RFR CMPT will save the data of two separate users. Meaning this is one you can share. 

Track the speed, distance and time of your rides and compare to your annual averages. Plus it comes in a variety of colours.

It looks a little old school, but the Lezyne Mini GPS was awarded 4.5 stars when our BikeRadar expert testers put it through its paces.

Okay, so it’s a little above the threshold to be classed as cheap, but we had to include the Garmin Edge.  

As well as tracking core ride data, this little gadget will sync with WiFi or Bluetooth for live tracking, incoming calls and text alerts.

Its display is fully customisable to show just what you need and uses GPS and Glonass to give you position information.
