The Misfit Shine is one of the cheaper options on the market – and as well as being able to track calorie burn over cycling, swimming, and a host of other sports, it can also provide you with data on distance ridden.

You can connect the device with MapMyFitness and MyFitnessPal, and it also tracks your sleep – time spent in slumber and its quality.

The lights that feature around the edge of the device aren’t just there to compliment the stylish design (which is customisable – you can even pop the pebble shaped tracker into a necklace!) either. You’ll set yourself an ‘activity goal’ for each day, and a full circle of LEDs means you’ve earned your evening on the sofa.

Initially available from Misfit in America, you can now get these from a range of suppliers in the UK, from around £60. 

If you’re after something really inexpensive, there is the Mi Band, at under £30, but this tracks activity via steps, so though it could help you analyse day-to-day activity, it won’t track your cycling so well.
