On a very basic level, all GPS bike computers will display simple data like speed (current/average/maximum), time and distance (trip/total), but that’s only scratching the surface of the capability of most units. Broadly speaking, GPS computers fall into two categories: those with mapping and those without. Computers with detailed mapping and turn-by-turn navigation will cost more than those designed simply to display ride data (although they may also have basic mapping functionality). If you like to explore by bike, buying a GPS computer with mapping and navigation is a great way to head into unchartered territory, without getting completely lost. But the latest software update to Lezyne’s phone app adds Komoot integration, which lets you select the Komoot Tours menu option on your phone to get a listing of your mapped routes and select one to follow, which is then pushed to the GPS unit. Komoot provides a more intuitive route builder and a menu of other people’s rides to tap into.

Two things should determine the best bike computer for you: the features required and the amount of cash you are willing to part with. Needless to say, the more you spend, the more advanced your computer will be, but that’s not always a good thing. I was a bit pessimistic when the Lezyne Super Pro GPS unit showed up at my door. Over the years, a few companies have tried to take on the two giants of the on-bike GPS units and had little to no impact. Lezyne, known for its tools and accessories to enhance your time on and off the bike, has stepped into the proverbial GPS heavy-weight ring with its latest offerings of devices. Lezyne Super Pro and Ally + mobile app Note: Whenever you perform a firmware update by connecting the device in bootloader mode, you will need to do a second update afterwards. Failure to do so may cause problems with future updates. The Super GPS has a mapping feature that is unique to the Lezyne models. Using the Ally V2 application, a destination can be selected and the application will give you routing options from your location. The application will provide you with 1-3 options that you can select by tapping the route on your smartphone screen. Once a route is selected, it will send the route to the Super GPS. As you ride, turn-by-turn directions are displayed on the screen.To update your Lezyne GPS unit, you'll need a Windows or Mac computer. No other operating systems are supported.

Lezyne also makes the Micro C GPS(also tested), which is incredibly small and lightweight and boasts all of the same features of the Super GPS with a color screen. Lezyne's Super Pro GPS is stuffed with functions and connects easily to other sensors/apps, plus it's light, securely mounted and stays charged for potentially weeks. The navigation is poor, though, and it's not a huge step on from the older Super Navigate GPS. The computer also now sync's with the Komoot and Relive apps for users interested in the features those provide. The Komoot app can aid in route planning for touring and road riding. Setup on the computer itself is simple through Lezyne’s companion app, with all the data options you’d expect and need, as well as phone alerts thanks to Bluetooth Smart connectivity. The computer can auto-sync ride data to Strava, but it’s pretty slow. The device is chunky, but then that huge battery has to be housed somewhere. FAQ What is the best GPS computer for cyclists?

Note: the file size of the map on the app is significantly larger than the size of the map file on the GPS. Once that measurement is sorted, cycling computers can work out your distance, average and maximum speed, and your ride time. You may not need all that data, or you may need far more if you’re training for a race or competition.
