Rated 5 out of 5 by from Excellent cycle computer I'm writing this review to upgrade information contained in the previous review. This computer comes out of the box with firmware vs 3.0. If you take the five minutes or so to upgrade to 3.3 (the latest firmware) you will have no problems paring a speed sensor to the computer. Upgrade the firmware via Garmin Connect. Once paired you must ride the bicycle approximately one mile in linear distance with GPS working to "calibrate" the speed sensor to your wheel size. Once that is complete the computer will use the sensor when ever the GPS signal drops or you put your bike on a trainer. It does so seamlessly with no input from the rider.

Rated 2 out of 5 by from caution Using the 3.0 firmware, the Edge 25 was unable to identify and link to my Wahoo SC ANT+ speed and cadence sensor. In trying to debug this issue, I also discovered that the Edge 25 will not use speed data from an external sensor unless you turn off all satellite connectivity (i.e., run it in "indoors" mode). I am not sure why they would hobble their device like this. In any case, I will attempt to return it and get a 520. On a positive side, set up of the device itself was simple and straightforward, and the small form factor is a major asset. I really wish this would have worked.

Rated 5 out of 5 by from Good compact GPS This GPS is compact/ pairs easily with bluetooth devices and provides plenty of information for average everyday rides. Pros/ compact/ easy to use/ pairs easily with ANT stuff... the GPS unit is "follow only" on routes you preload from garmin connect. Not a worry for me.... others riders might want more detailed maps. Cons/ battery life is around 8 hours. For me this unit is a 10.... I am a fan of Garmin and of REI.... you can't go wrong with customer service on either end. avid biker/commuter

Rated 4 out of 5 by from Paired down GPS bike computer I previously had the Garmin Edge 500 and this year used my dividend to get this computer. It is tiny and practically weightless. Things I like about it. It acquires satellite signal very quickly relative to the Edge 500. Simple to use downloads and links with Strava easily. Things I don't like. It does not allow for time of day to be displayed, or compass direction. Those are two features I like when I'm out on new routes.

Rated 4 out of 5 by from Great GPS unit for the price PRO: Cost, programmable displays, programmable courses, connection to Strava/MapMyRide, size, turn-by-turn navigation CON: Monochromatic display, Bluetooth connection is difficult I bought this to replace a Specialized Sport computer, after about 250 miles, I’m loving it! NOTE: I have the cadence bundle but the head unit is identical. The unit is small and can mount to handlebars or stem. The cadence sensor attaches a crank arm and both the unit and sensor were installed in under 10 minutes! The unit allows you to program you displays which auto-scroll during your ride. You can select the scroll speed. One screen is always time and date. The other two are programmable. You can select ride time, distance, speed, average speed, calories, cadence (with sensor installed), total ascent (GPS data only), and elevation (GPS data only). The display does NOT have a pace arrow, but I have speed and average speed on the same page, so I can tell with a glance if I’m keeping on pace or not. There is a backlight which can be turned on with a push of a button or can be set to remain on while the unit is powered. Since I ride early morning, this is a very nice feature. No more waiting for the next streetlight to check my pace! The GPS acquires very quickly. So far it’s been ready to go within two minutes of moving the bike outside. Through Garmin Connect you can import ride data into Strava or MapMyRide. Garmin advertises that live tracking through Bluetooth is available, but I’m been unable to synch my unit with my Iphone. Looking on line, I see that lots of folks are having difficult synching different Garmin products with IOS, so I don’t think it’s ‘operator error’. Creating a course is very simple through Garmin connect. You locate where you want to ride on a map and then start clicking your route. Another click and it’s sent to your unit. When you ride a course you’ll get prompts of upcoming turns. You get a ‘beep’ and then a countdown in feet until the turn. There is also a graphical depiction of which way you turn; this is a nice feature. When you hit the turn, the unit beeps again. The display just shows you a black line for the turn, there is no map data in the unit. You can also just hit start and the unit will start displaying and recording your ride. This only takes two button pushes to start. The unit is an inch and a half square, so there is definitely room on your stem or handle bars to mount. The cadence is a wireless unit that is completely self-contained. You do not need a magnet on your crank and an ANT+ sensor on your chain stays. The battery is rated for 8 hours and so far my longest ride is 3 hours. Even with the backlight on continuously, I was able to get two 3-hour rides between charges and I never got a low-battery indication. One drawback is the screen is monochromatic, but to move up to a color screen was at least another hundred dollars. Overall, I am very pleased with the unit. I have not noticed a difference in the data from my old computer which uses a mag pickup and the course programming is very nice when I want to ride a new route and am afraid I’ll take a wrong turn and get lost. The only reasons I'm not giving 5 stars is the Bluetooth issues (with all Garmin products as I'm learning on line) and the monochromatic screen.

Rated 2 out of 5 by from Unsuitable for MTB Bottom line: Turn-by-turn is useless for mountain biking. Suggest looking at the Lezyne Micro in this price range. Cons: *Turn-by-turn directions are strictly angle-based from track data, giving rise to hundreds of turn instructions for a mountain bike trail. Any CoursePoints in a TCX file are ignored. Same behavior when going through Garmin Connect or direct upload to the GPS via USB. *Re-establishing Bluetooth connection back to the phone is hit-and-miss. *No slope/grade display field is available *Proprietary charging cable Pros: *Does give audible/visual off-course warnings from breadcrumb routes (even GPX-based ones) *Mount is sturdy *Virtual partner is very cool

Rated 1 out of 5 by from Not as advertised Beware - you cannot add BPM as a customized data field. Such a basic feature that is advertised and described in manual. I want to see cadence and BPM when riding and this device was supposed to provide that option. I agree with other reviews that this device is definitely in the beta phase. I will definitely be returning it.

Rated 1 out of 5 by from Still needs a lot of work from Garmin New to the Edge series devices, the promotional videos here on REI and the Garmin website make the device look super refined and sexy. If you use the device on its own (meaning you do not connect it to your smartphone or synchronize it with the Garmin CONNECT web portal), it’s an alright device. It’s great at the advertised stuff of tracking speed, location, elevation, and mapping your ride. Again, if you set up your settings directly on the device and never sync with your phone/computer – it’s fine. But what’s the point is spending that much money for a device that you can’t read out all of the telemetry and keep an online journal of your rides? Here are the problems I’ve ran into so far… 1) Bluetooth on this device is terrible, meaning after my initial pairing with my smartphone – every time I turn on the Edge 25 I have to tinker with the device to get it to pair with my smartphone. 2) Setting up the device (ie customizing the screens and the settings) is non-trivial and works fine. The problem occurs when you sync your settings via smartphone or computer to the Garmin CONNECT web portal. Garmins’ Connect portal in theory is pretty cool where all of your device settings and rides are all saved to the cloud (Garmin Connect) – again pretty spiffy in theory. Problem occurs when you modify and try to save your Edge 20/25 settings via CONNECT and sync it back to your device through USB connected to your computer or smartphone sync – the device and CONNECT never stay in sync. It always overrides your settings, or just flat out never saves your new modified settings. 3) Pairing the Edge 20/25 with Garmin’s new magnet-less speed sensor and cadence sensor is pretty quick and painless, but getting them to “wake-up” after the initial pairing for your second ride is a disaster. I’ve gone with whole rides where they will not re-pair with my Edge. These are my biggest gripes with the new Edge 25, I really hope that Garmin roles out with a newer software version quickly. I will update if anything gets better with the new software version. The Stuff: - Garmin Edge 25 (REI: 893355) Running software version 2.5 - Garmin Bike Speed and Cadence Sensor (REI: 876303)

Questions & Answers

Does the Garmin 25 record and report the total elevation gained and lost during a ride?

Asked by: Up and down
This bike computer does display current elevation. It will also calculate total ascent. It does not calculate elevation losses.

I realize this is designed to be used with a bike, but, I would like to use it when I paddle my canoe as it gives me the data I require (speed and distance ) in an easy to ready format , will it be "splash proof " enough for this ?

Asked by: Robster
​This item is built to withstand rain, splashes, and incidental exposure to water of up to 1 meter for up to 30 minutes. You could use this on your canoe to view your speed and distance.

Does it provide turn-by-turn navigation? If so, can I give it a new course from my phone? Or do I need to plug it into a computer to do this? Thanks!

Asked by: nycnick
​This bike computer does provide turn-by-turn prompts. Additional courses can be sent from your phone to the computer via Bluetooth using Garmin Connect.

1. Will it work out of the bike mount so I could use it on hikes, and similar? 2. Is it waterproof so I could use it during a swim?
