What customers say about "Key Specs"

Garmin Edge 20 Cycling GPS

The unit is very accurate in recording GPS. In addition to using American GPS, it also uses Russian GLONASS if you turn it on in the setup.
This unit is not for the needless data nerd or the geek that wants a tablet sized computer to show a color map on their handlebars. I carry a smartphone in my bike jersey pocket and I can always pull that out if I need to look something up on a map or get directions.
The Edge 20 is an great minimalist bike computer. I'm not at all interested in connectivity with sensors... I just need the basics and gps ride data and the Edge 20 delivers exactly that reliably.
This unit tracks my trainer sessions with no issues, and even saves on the battery since it turns the GPS off for indoor rides.
This is a simple gps-based meter, with minimal but useful routing/gudance functions. If you are looking for a full-function gps with elaborate routing and other functions, this is not it.

Garmin Edge 25 Cycling GPS

I have owned this Garmin Edge 25 for about two months and it has worked perfectly. It did flake out a little on me after one of the software updates but after I reloaded the software again, it was good to go.
That being said, I love this thing. It definitely saves my phone battery by not having to run strava for hours at a time.
The GPS finds satellites very quickly.
Build-in GPS tracking. No wiring or sensor needed to be install on your bike.
GPS is not always reliable. It could give you false reading and long GPS lock.

What customers say about "Display"

Garmin Edge 20 Cycling GPS

The unit is the same size as a wrist watch but a little bit thicker. I'm sure this model is an adaptation of Garmin's wristwatch models for runners.
Display was clear and made it easy to see total time, total distance and current speed at a glance, which was all I wanted.
The unit is VERY small and lightweight. If anything it is almost too small if you have bad eyes and/or big fingers (vs the small buttons)... but should work well for most people.
I like it, but setup was initially a bit confusing. Time I wish was displayed while you are riding.
Very small screen with limited data fields.

Garmin Edge 25 Cycling GPS

The screen is very easy to read. You can flip between a clock, a 2-line data screen, 3-line data screen, a very rough map when you reload and follow a course, pacing for the preloaded course and heart rate functions if you buy the optional heart rate sensor as well as cadence sensor.
The display is just big enough to give me the info that I have to have and I can read it while riding down the trail I monitor speed, distance and HR all the time. There is LOTS more info if I need it.
It's small, lightweight, and I like that it fits on my stem. Easy to read, and seems pretty reliable.
The physical design is perfect, as it is small but still easy to read.
Excellent little unit. Have had it for close to a month and I've only needed to charge it once. I would rate it 6 stars if it had the ability to display max speed on the screen (you get it later using Garmin Connect or Strava).

What customers say about "Features"

Garmin Edge 20 Cycling GPS

It was very simple to setup and configure this unit. It usually acquires the GPS satellites immediately after it is powered up.
Performance is reliable and on par with my iPhone + Bike Brain and Strava. Also it weighs nothing! All in all its a great little gps computer and a tremendous value.
I like time, distance, speed, average speed, and total ascent. You could substitute calories or elevation. It has a USB connection for charging and data transfer.
One feature that I miss from my old Forerunner is a slope indicator. It wasn't always that accurate on the Forerunner, but I liked having an indication of how steep my climb was.
It does not have Bluetooth, so it won't pair with your phone.

Garmin Edge 25 Cycling GPS

The 25 pairs to my smartphone perfectly and downloads automatically. It also pairs to my cadence, speed and heart rate sensors.
With 4 buttons, you would think it would be easy to put the thing into the same time distance speed display I would use on pretty much every ride.
This little device is amazing and was very easy to set up. I like the ability to add Ant+ devices when desired and the ability to link to the iPhone.
Very lightweight. Mounting seems a tad sketchy, but so far no failures--will update. After the ride gives you vertical distance climbed and calorie burn.
There are a couple of issues with the bluetooth connection to my phone.

What customers say about "Battery"

Garmin Edge 20 Cycling GPS

The battery seems more than sufficient for the average bike ride of 1 to 3 hours. I ran my for 9 hours one day with no problem.
It charges with a USB plug that plugs into your computer. It does not have a standard USB style jack on the GPS side but it does have special contacts.
Battery life is acceptable, hours better than my iPhone.
Battery was only halfway depleted at the end. Distance recorded was spot-on the distance of the ride according to the cue sheet (101.9 miles.) Extremely pleased with this purchase.
Nice compact design from Garmin with many features, but huge downside is the very short battery life (less than 8 hours).

Garmin Edge 25 Cycling GPS

I like the Edge25 for its simplicity and (very) small size. After 6 months of use, I generally get about 8 hours from a full battery charge
Battery life is good. Lasted on an 8 hour ride, but I also have the Bluetooth turned off.
If the duration of this battery is long, still better
Battery holds a good charge. I've done several 2-3 hour rides on it. I charge it before each ride and it's always shown 3/4 full on battery at the end of my rides.
What is a drawback is the charge only lasts a few hours. I used up half the charge after riding just over 1-1/2 hours. At most I will get 4-5 hours max of operation before the battery is used up.
The battery was good for maybe three 2 hour rides before it needed to be recharged.
