Now that the market for standalone sat-navs seems to have reached a level of saturation, and smartphones are putting up some serious competition, GPS makers are branching out. Although Garmin has been doing sports GPS devices for years, Mio is a relative newcomer, having entered the market with the Cyclo 300 series in May 2012. The Cyclo 100 series is the next member of this new range aimed at cyclists, and the 105 HC is the top product in the series, alongside the 100, 105, and 105 H.

Mio Cyclo 105 HC: Features

The differences between the various models revolve primarily around the bundled extras. The basic 100 unit is a cycling computer, without the navigational features of the 300 series. So you can’t use any of the 100 series as a stand-in sat-nav. But you can still download your workouts via USB and view them online using the Mio Share desktop application. The 105 model adds a wireless ANT connection for hooking up peripherals, and the other two models bundle these peripherals. The 105 H comes with the heart-rate monitor, whilst the 105 HC we were testing includes a cadence and wheel sensor as well.

The basic 100 series unit is a tidy little device not much larger than a box of matches, finished mostly in black plastic with a white bezel. This unit is IPX7 certified, meaning it is waterproof to an immersion depth of 1m, but has no specific tolerance to dust ingress or being dropped. You attach this device at a convenient spot your handlebars using a mount that straps on using a couple of sturdy plastic cable ties, which won’t be ideal if you want to use the Cyclo with multiple bikes, as they aren’t designed to be easily removed. The mount is intended to remain on your bike whilst the device can be docked and undocked as required, although you could install multiple mounts on different bikes.

The screen is a monochrome LCD, which can be backlit at the press of a button. Entering the setup information when you first turn the device on is rather laborious, as you have to enter your age, weight, height, and information about the bicycle you are using, including its type, wheel size and weight. The information has to be added by scrolling through character lists, and the text is a little small and hard to see. But you only have to do this once, then operation is a lot simpler. The Cyclo essentially works like a sophisticated GPS-enabled stopwatch, so will record your changing location as well as providing a timer with lap marker control. There are auto lap and auto pause options available in the settings, too, so the Cyclo will automatically mark laps for you and pause the timer if it detects you aren’t moving for a period of time, for example when stationary at a traffic light.
