Why We Like The Mega XL GPS Pro Loaded Bike Computer

We find ourselves investigating bike computers with greater skepticism as our smartphones get smarter by the day. With cycling apps capable of capturing data, providing turn-by-turn directions, and connecting us with fellow riders, the bike computer is becoming a redundant piece of equipment for professional and amateur riders alike, hogging valuable real estate on our handlebars where other components could sooner find a suitable home. Or at least, it was becoming redundant until we mounted the Lezyne Mega XL GPS Pro Loaded Bike Computer and remembered once again how efficient and effective a bike computer can be.

The Mega XL embraces all the features we could ever want in a bike computer, and those features begin with the rugged frame that locks in place with the included x-lock standard mount. Once secured to your stem, the Mega XL can be positioned in landscape or portrait mode, though we prefer portrait mode because it displays a bit more map as you follow your route. Physical buttons on the side of the frame serve a variety of functions, from shuffling through data screens to turning on the backlight. The LCD display is crisp and easy to read, even on sunny days in the saddle.

Though the frame be but mighty, it's the built-in capability of the Mega XL that blows us away. Up to five data screens display ten fields of data each, for a grand total of over 50 different metrics, from ride time to electronic drivetrain data. Pair the computer with your phone via bluetooth or ANT+, and the Lezyne app allows you to toggle through the different data screens with ease, or see all the data screens on one page. And if the endless data becomes overwhelming, simply change the settings on the computer to display what matters to you most.

Aside from the plethora of data captured by the Mega XL, most riders will use it for GPS navigation. Downloading maps and uploading them to the device can be performed on a desktop computer, or with the Lezyne app. The desktop uploading functionality is quicker, but the phone application comes in handy when you find yourself in need of a map you don't have with nothing but your phone and a data connection. The Mega XL stores up to 800 hours of ride data, and the lithium polymer battery supplies a whopping 48 hours of runtime, far outweighing almost every other GPS bike computer on the market. Once you've finished your ride, upload data to your favorite fitness apps and stay connected with the pack.

It's OK...I guess.

I've put it through the wringer

The battery life is fantastic, and it works well for basic functions. The live tracking, which is primarily why I bought it, is beyond horrid. It seems to update every half hour or hour, even when cell data is good. I'd think when it does update, it would fill in all the missing data points, but no. You really need Ride With GPS or some such for the turn-by-turn to work well. Plotting a course using Lezyne software isn't fun. The altitude is roughly accurate, but changes in air pressure might show you at 570 meters one day and 560 the next. Slope is absolutely useless. On-screen maps are usually too small to be useful, but sometimes are handy if you think a road is coming up but aren't sure when. Open Street maps are superior to Garmin's and are updated constantly. You'll usually find all the trails and dirt roads in this unit, which won't be in Garmin's devices.

kinda disappointing

5' 11"

So I needed a new bike computer to replace an old polar M450. My choices were narrowed down to a Garmin, Wahoo or this Lezyne. From these I ruled out the Garmin...just too expensive. I also wanted the HR and cadence. So here's my pros and cons after using the Lezyne for a couple of months: Pros: BIG screen that can be used either portrait or landscape mode. Insane long battery life. I even have the refresh set to the fastest possible. easy to use app. Cons: Ultra cheap plastic on the HR monitor. One of the dog ears for the battery compartment broke right away. Lucky I had a polar HR monitor that works fine with the computer. Really annoying buzz/rattle from where the computer attaches to the mount. I added an o-ring to computer lug where it twists onto the mount...it helps but does not totally solve the problem. Buttons are very small and not intuitive. Very innacurate/unreliable grade% calculation and climbing feet readout. I hear that there's a fix for this, but I shouldn't have to fix it. Calories burned are calculated by bike speed...not heart rate. If I would have known this fact alone, I would have ruled out this computer.
