Cycling computers are a handy addition to the road bike for a number of reasons. They’ll chart your speed, tell you the time, tell you how many calories you’ve burned, give you info on your cadence (how quickly you are turning the pedals) and inform you how much ground you’ve covered.

It’s all interesting information that can be motivating, and is invaluable if you are training.

Different computers will give different feedouts, from the basic speed, time and distance right up to heart rate, power, and GPS systems that plot your route or guide you along.

A lot of these feeds take information from a sensor attached to the front wheel and forks. At the lower end of the price scale, this sensor will attach to the computer with a cable. Further up in price and the sensor is wireless.

For feeds on your heart rate and cadence, you may need to get additional items, or you may be able to get the computer with a bundle of accessories included. Heart rate monitors, cadence and power meters, and GPS maps are some of the options.

A basic computer starts around £15, and you can spend up to £500 for a top of the range computer with GPS and accessories.
