The new Garmin Edge 20 and Edge 25 have arrived and we have the pleasure of reviewing it here. This compact little GPS bike computer replaces the Edge 200. The Edge 20 is pretty much a direct replacement of the 200, but the Edge 25 supports ANT+ accessories (HRM, cadence) and Bluetooth smart connectivity to your phone. This can be used for data transfer post ride, direct to Garmin Connect APP and also, if you want it, Smart Notifications from your phone (texts, incoming call etc). The Garmin Edge 25 has been reviewed by Tristan Haskins aka Cardio Critic (was HeartRateMonitor UK)

Garmin Edge 25 product review by Tristan Haskins

Simple, Brilliant …. SIMPLY BRILLIANT

Thank you Garmin for giving us all something we can use straight out of the box. This fantastic little GPS bike computer delivered EVERYTHING I wanted it to and give me a whole lot more. It’s been a real pleasure testing the Edge 25 and it will certainly be one of the products I recommend most over the coming months. Garmin have given us a simple to use, BUTTON operated (no fancy touch screen) GPS bike computer with optional heart rate and pedal cadence support. Added to that it has WIRELESS data download to the Garmin Connect APP using Bluetooth Smart technology. The only time you really need to plug it in to the USB port of your Mac or Windows PC is when you want to charge it.

Differences between the two models?

Let me answer that like this… unless you absolutely have a FIXED IN STONE budget, get the Edge 25. The Edge 20 is really not much more than a direct replacement to the Edge 200. The 20 does NOT have ANT+ connectivity, neither does it have Bluetooth Smart network connection. What this means to you is that it will NOT support … 1) Heart Rate belts 2) Pedal Cadence sensors 3) Bike Speed sensors (for indoor training) 4) Bluetooth data upload to your smartphone 5) Smart Notifications to the Edge unit from your phone…

Headline Features

Let’s cover the primary features that you will get with the Edge 25. In the list below I have highlighted in orange the features that the Edge 20 does NOT have.

  • Speed and Distance
  • Simple turn by turn route navigation – following a downloaded COURSE
  • 8 hour battery life
  • Personal Records – longest ride, highest climb etc
  • Targeted Ride options -> Free ride (default), Distance, Calories or Time based.
  • Route Recording. Your route is recorded for later analysis or sharing with Strava, MapMyRide etc
  • Backlight (top right button)
  • Calories burnt
  • Barometric Altimeter (more accurate/sensitive than GPS based)
  • Standard Garmin Quarter Turn lock
  • Comes with 2 x Bike Mounts and multiple silicon fastening bands
  • Dual GPS options. GPS (default, regular US system) and GLONASS (Russian system)
  • Heart Rate via ANT+ HRM strap
  • Cadence via ANT+ optional sensor
  • Indoor Speed via optional ANT+ sensor
  • Smartphone DOWNLOAD of data via Bluetooth Smart to Garmin Connect APP
  • Smartphone NOTIFICATIONS to Edge 25 eg. incoming call, text etc.

Next model UP

The next model up is the Garmin Edge 520. The 520 adds Strava segments, colour display, longer life battery and touch screen control.

Edge 520

Alternatives?

The best alternative to the Garmin Edge 25 is the Polar M460. The Polar M460 replaced the brilliant M450 with the addition of LIVE Strava Segments. The Garmin is a brilliant unit but the M460 is worth the extra £50/$70 investment

Pros

  • Very easy to use
  • Large clear display
  • Garmin quarter turn locking system
  • Heart Rate & Cadence support (Bluetooth 4.0)
  • GPX route follow
  • Supported by the brilliant iPhone & Android app - Garmin Connect
  • Great value for money
  • Cons

  • No power monitor support .. but should we expect that from this model? no ....
  • Next model DOWN

    The model below would have to be the legacy Edge 200. In my honest opinion, unless it’s on offer for less than £40… I’d get the Edge 25. Remember, the Edge 20 and Edge 200 do NOT support heart rate or cadence (via ANT+) or smartphone connectivity via Bluetooth smart….

    Really… OK.. Edge 200

    Edge 25 Video Review

    We’ve reviewed the way we’re presenting our product test reports and we’ve decided to get the video in a bit earlier. Please remember, this is OUR OWN video created by Tristan at home with his trusty Sony Alpha 6000 camera. It’s NOT a marketing department smoke, mirrors and special effects video it’s just me, the Edge 25, a camera and a cuppa Tea. It’s unscripted and basically just goes with the flow. Anyway, I hope you like it. It covers pretty much everything from initial set up, to getting ready for a ride and downloading training data.

    >> back to Edge 25 review

    Back to the test review

    Let’s go through some of the main screen and features of the Edge 25. We’ll start with the primary screens. The screen below is the primary ON screen. It’s clean and uncluttered. We have battery life top left, GPS satellite strength middle and VERY CONVENIENTLY, time of day top right. You may also notice around the outside of the case the 4 x button decals. They perform the following functions

    • Top Left – ON/OFF and Backlight when turned on
    • Top Right – GO/STOP and ACTION commands/menu options
    • Bottom Left – Go Back / Go Up a level
    • Bottom Right – Scroll down through options

    Edge 25 - Ready to ride welcome screen

    From this view, scrolling DOWN with the bottom right will switch between

    • RIDE
    • COURSE
    • HISTORY
    • SETTINGS

    Ready to Ride

    Once you have pressed the Top Right button from the main menu you are presented with 3 different options before you ride. If you know what you’re doing and just want to go for a simple ride, simply select RIDE MODE then press the same button again to get going.

    Otherwise, you have the option of selecting various RIDE MODES, setting up HR ALERTS or putting the Edge 25 in to USE INDOORS mode with GPS turned OFF. This would be used if you were on an indoor bike/turbo trainer and wanted to use the unit as a speed, cadence and HR monitor.

    Selecting your RIde Mode

    Polar’s alternative for consideration

    If you are interested in a an alternative to the Garmin Edge 25 then we would ask that you consider the Polar M450. It’s a mid-sized GPS bike computer packed with similar functions as the Edge unit. In addition to all the standard speed, distance and altitude feedback, like the Edge 25, you also have the option of Heart Rate, Pedal Cadence and a wheel speed sensor (great for rollers / turbo training) PLUS, the M450 can support Power Meters (Bluetooth SMART like Polar Look Keo, PowerTap or Stages Power cranks). With the M450, reviewed here, you also get a deeper insight into Training Load and Training Benefit from each session plus a built in Fitness Test. It’s all supported by a very competent iOs and Android app, Polar Flow (all data is also uploaded to flow.polar.com web-service)

    Ride Options

    Most people will probably want to go for a BASIC ride. If that’s the case, just press Top Right and GO RIDE. Otherwise you have the following options

    • Follow Course. Assuming you have downloaded a previously ridden course to the memory of the unit, you can follow that same course and be given TURN BY TURN instructions. This is NOT a full autorouting/mapping feature. It just follows a GPX course, telling you when to turn left/right etc. The COURSE must have been downloaded from Garmin Connect website. It can be one of your own, or someone elses. It’s a GREAT FEATURE for riding in new areas and/or sharing rides with friends.
    • Time. This lets you set a target TIME to be riding for and gives feedback throughout to ensure you reach your TIMED objective
    • Distance. Similarly, this allows you to set a DISTANCE based goal, eg. 30 miles
    • Calories. Ditto

    Choosing your ride options

    Training Page Views while Riding

    One of the attractions of the Edge 25 is it’s simplicity. This is highlighted in what you see when you are riding. You have 2 or 3 training pages to view. The Edge 20 only has 2 as it does NOT have heart rate. The third page view on the Edge 25 is Heart Rate Actual and Heart Rate Zone (1 to 5)

    Training Page 1 (below) is split in to 3 segments. Training Page 2 (below, below) is split in to just 2 segments. The user has the ability of selecting that data is important to them. The options for the display segments are:

    • Time
    • Distance
    • Speed
    • Avg Speed
    • Calories
    • Cadence
    • Total Ascent
    • Elevation

    training-page-1-DSC00928 Edge 25 Training Page Views

    The Edge 25 has a THIRD VIEW which is dedicated to heart rate (forgot to take a picture, sorry) but you can see it in the video review.

    You want more… OK

    So, you’re still here. We’ve looked at what the Edge 20 and Edge 25 do and what they don’t do. We’ve looked at how to set them up and go for a ride. What we’ve not looked at is POST SESSION review data.

    Historical Data Review

    Remember, the beauty of these new Garmin Edge units is that they effortlessly download training data to Garmin Connect via Bluetooth. However, if you want to review your data on the unit, you get a pretty good summary there too…

    In Conclusion

    The Garmin Edge 25 is the perfect blend of size, functionality, battery life and techie features. We have really enjoyed testing it and we HIGHLY RECOMMEND it to anyone looking for a sensibly priced GPS bike computer that does pretty much everything you’ll need when out riding. Remember, it does NOT support MAPPING/AUTOROUTING and it does NOT support POWER meters. Apart from that, it does everything most cyclists will need for daily training and it’s supported by the very competent Garmin Connect APP. I have awarded the Garmin Edge 25 a solid rating of 4.5/5 stars
