A bike computer makes the details of a ride easy to see without pulling out your phone. Whether you want to check your speed on the commute, keep track of weekend mileage or follow a new route, there are useful options for less than £100. The best choice depends on how much information you actually want on your handlebars.

Why Buy a Bike Computer?

For many cyclists, seeing distance, speed and ride time at a glance is reason enough. A simple computer can help you notice your progress, pace a longer ride or work out how far you have left to go. If you enjoy exploring unfamiliar roads, a GPS model adds route guidance. You can spend more for advanced training features, but you do not need to spend more just to make everyday rides easier to follow.

Who Are Budget Bike Computers For?

Commuters and leisure riders may be happiest with a straightforward display that starts recording when the wheels turn. Road and gravel cyclists who plan routes or use training sensors will get more from GPS and connectivity. If you ride several bikes, check how easily the computer and its sensors move between them before choosing.

Popular Models to Compare

The Magene C506 Smart GPS Bike Computer offers the most features of these examples.It has a 2.4-inch colour touchscreen, turn-by-turn map navigation and support for compatible sensors, including heart rate monitors and power meters. Magene currently lists it at £99 in the UK, putting it just inside this price bracket. It suits riders who want routes and ride data in one device, although its rechargeable battery adds another item to remember before heading out.

If maps are unnecessary, the Cateye Velo Wireless keeps things simple with a wireless speed sensor and an easy-to-read display. The Cateye Quick Wireless Cycle Computer takes a different approach, with a distinctive display and an integrated out-front bracket. Both are worth considering for rides where speed and distance matter more than GPS tracks or app features.

The Sigma Pure 1 Cycling Computer is another back-to-basics option. Check the exact listing when comparing deals, as the Pure 1 is wired, while the similarly named Pure 1 ATS is wireless.

Pros and Cons of Spending Under £100

The main advantage is choice: you can buy a tidy display for essential ride figures or stretch the budget to a GPS computer with navigation. The trade-off is deciding which features you will use. A basic wheel-sensor computer will not guide you around a new route, while a GPS unit needs charging and a little more setup.

Which One Should You Choose?

Start with your usual ride. For commuting and familiar loops, a Cateye or Sigma may tell you everything you need. For planned routes, Strava uploads and sensor data, look closely at the Magene C506. Then compare the current offers on this page from different online suppliers, checking the exact model and what comes in the box before buying.
