What customers say about "Key Specs"

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.

Garmin Edge 520 Bike GPS

Easy to use, no issues with connection, great set of items to display.
The size/weight is perfect, screen is always legible.
I like the size, features and downloads to my iPhone.
Great GPS system, perfect size and full of features!
Acquires GPS satellites much faster, and the Glonass is very good to have as well.

What customers say about "Display"

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).

Garmin Edge 520 Bike GPS

I like the compact size, yet still a big display.
Display is bright, and I was surprised how readable it is considering it's color display.
The larger display compared to the wrist models is great, and it has true mapping capabilities.
Screen size is good. Not too big and not too small. It has enough squares to get the information I want on the screen.
There was so little contrast on the display that it was practically unreadable no matter the lighting.

What customers say about "Features"

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.

Garmin Edge 520 Bike GPS

With the auto scroll setup I'm able to see more data and my route.
I'm using bluetooth to sync to my phone and finding the Garmin Android app to be much more useful than it was with the Garmin 25.
With my mobile phone's bluetooth, I'm able to effortlessly synch my ride to garmin connect and auto upload it to my Strava account.
I added a speed transmitter primarily for indoor training, then I added a rpm transmitter and I just added a heart rate monitor transmitter. The information it supplies me is great.
Constantly says I'm off course when I'm using a pre-planned route.

What customers say about "Battery"

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.

Garmin Edge 520 Bike GPS

After 3 hours of use the battery is on track to last about 10 hours with gps.
One thing that I have enjoyed is the long battery life. I ride about 140 miles a week which takes 7+ hours and only have to charge it about once every other week.
Love this, battery life is great.
At night there is a backlight that does drain the battery somewhat rapidly.
Battery runs down after only 3 or so hours, so it has to be charged after every ride.
