  • Garmin Edge 520 Cycle Computer

    The Garmin Edge 520 Cycle Computer is the first device with Strava live segment challenges. This aerodynamic GPS bike computer is packed with advanced analysis features like time in zone, cycling-specific VO2 max and recovery time (when used with a power meter and heart rate monitor). It has a 2.3” high resolution colour display, providing great visibility in all lighting conditions, in a lightweight compact device. When paired with your compatible smartphone (Android 4.3 and above and iphone 4S and later) and the Garmin Connect™ Mobile app, Edge 520 offers live tracking, smartphone notifications (allowing you to receive text and call notifications while riding), social media sharing, weather updates and automatic wireless uploads. Once your ride is complete, the data can be automatically sent to Garmin Connect™, Garmin’s online community where you can analyse post-ride stats, including cycling dynamics and save, plan and share your rides.

  • Garmin Edge 520 Cycle Computer is rated 4.7 out of 5 by 48.
    Rated 4 out of 5 by from Good Computer (if you know where you are) I bought this to replace my old edge 800 as I wanted Bluetooth. I was very pleased with it initially although the buttons are a bit awkward. It's real weakness is the quality of the preloaded map. It's really poor, doesn't show junctions or road numbers making it very difficult to navigate. The preloaded map can be replaced but the internal memory is too small to load a significant area. This was a real problem for me so I returned it and bought an edge 820 instead. Otherwise very good. Like I said in the title its ideal if you know the routes you cycle, if not you'll miss a lot of turns.

    Rated 5 out of 5 by from Garmin Edge 520 I had looked at several cycle computers online before making this purchase. This computer has all the features a keen cyclist needs. In addition to the obvious speed, distance travelled, time taken etc. the 520 links perfectly with Strava meaning (providing you have a Premium membership) segments are displayed in real time. It also has a feature for 'virtual' racing or racing against your previous time. The battery life is good, display screen excellent, it fits securely either on the handle bars or stem. I like how it links with Garmin Connect which gives more analysis than any amateur cyclist needs. I would recommend this product.

    Rated 5 out of 5 by from Great GPS Device Bought as an upgrade to the Garmin 200 I've been using for the last few years. Easy to configure and tailor the display to your own preference. Set up different profiles, one for MTB and one for road bike. Highly recommended

    Rated 4 out of 5 by from Great Bike Computer Now that I have used it a few times and still learning all the functions I feel I can say that the Garmin 520 is a good piece of kit. There has been some dubious recordings linked with Strava so I would say don't rule your life depending on Strava. I wish I got the one with maps but this GPS unit does all my needs. Came with two mounts which suited me one for each bike It remains sturdy in the mounts provided even over very rough terrain. I used my British Cycling Card to get some discount. Helpful staff gave me a demo a few days earlier which influenced my decision to buy the Garmin 520

    Rated 5 out of 5 by from Perfect training, not for exploring. Brilliant, GPS unit, clear screen, I have just four fields for visual ease at speed. All metrics are covered, power, cadence, heart, speed, each field can be view in multiple ways over several pages. It's an idea device for training, it has maps and can follow a breadcrumb trail with turn by turn guidance, just note it doesn't navigate, it can only follow the route you upload to it. The buttons are much friendly than a touch screen with winter gloves on, menus are intuitive and famiiar with other Garmin devices. Perfect device for training when paired with Connect, Strava and others, def recommend.

    Rated 5 out of 5 by from Smart technology on the move. This Garmin Edge in my eyes is the perfect size, not too big and cumbersome but packed full of features sumilisr to it’s big brothers. Still learning the features that come with it but I wished I bought the sensors with it but due to the costs I could only get the basic setup. Not disappointed with the Edge 520
