OMG a what an ordeal!!
3 out of 5 stars
OMG a what an ordeal!!
I am pretty handy but installing this bike computer drove me NUTS! The biggest pain is programming it. The instructions are not accurate/not complete/not clear. As a result, I had to start over about a dozen times until I figured how to press the right buttons in exactly the right sequence to progress from one setting to the next, in order to set the bike tire circumference, miles/KM, time, etc. Once you go too far, it will not let you go back—ever. The only way to start over is to remove the battery and replace it. That removes ALL the settings and concerns me because when it’s time to replace the battery, it means I will need to completely reprogram the thing. UGH!!! One setting is the tire circumference. That’s the measurement all the way around the outside of the tire. It tells you a handy way to do that by measuring between two marks on the floor. But you have to know the circumference in millimeters. They give you some whacked way to get that. But a much simpler way to do it is to use Google to convert the inches to millimeters. It instructs you to wave the magnet (the one that attaches to the tire spokes) across the sensor to confirm it’s working, and then to install the sensor to the front fork not more than 3 mm from the magnet on the spoke. But in order for it to register, the magnet (on the spokes) needs to be almost TOUCHING the sensor. It’s difficult to get it within literally a hair’s distance, without actually hitting every time the tire makes a rotation. Overall, this is a good price. But I think other reviewers are correct in that you get what you pay for. I’d much rather pay another $5 or so, and get a bike computer that is easier to program and easier to install—even though all I wanted was a basic speedometer and odometer. I write honest reviews to help others make informed purchases because I read reviews myself and appreciate how helpful they can be. I hope that my review helped you!

    I'm very pleased with it. The first one arrived defective; as per Amazon online instructions I returned it via Kohl's and had a replacement on my doorstep the next morning.

    One think I was happy about was the mount. I didn't want to mount it on my handled bar but instead on the stem of the bike, which of course is perpendicular to the handlebars (please see photo). At first, I wondered if I would be able to do this as the computer mount appears to only curve so that it just be mounted on the handlebars, but happily I noticed that the bottom half of the mount can be flipped so that the computer could indeed change the mount's direction by removing a few screws flipping the curved part in a perpendicular direction, and putting the screws back in.

    After that, installation was a snap.

    Not every bicycle computer has a clock on it, this one does. I personally really like to easily know what time it is as I bicycle; for those like me, this computer has that capability.

    It did take some time to get used to which button to push to do what - see how many miles one had ridden (odometer), what the average speed is, flipping back so the clock displays, and so on, but it's actually pretty simple to do once you've ridden with it a few times.

    I found it to work the most accurately as far as speedometer and distance by measuring the circumference of my bicycle wheels using chaulk marks on the ground. Enter that measured circumference in into the bicycle computer's setup, and in my experience it was very accurate.

    The backlight is very bright and useful for viewing once it starts to get dark outside, and as you can see in the photo, the display is extremely easy to read.

    A reasonable wireless computer. Setup is easy, readings are accurate. Probably should dock 1/2 star because handlebar-mounted headlight causes interference with the computer and it stops working when lights are on but I guess that's a minor complaint since most rides are during the day.

    I wouldn't say this has any advantages over a wired computer. In fact, wheel sensor is much bulkier than one from a wired computer. There's potential to flood the sensor if you go into really deep water, and there's one more battery that will need replacing but the price was right so why not?

    Update: had this on my bike during hurricane Harvey. Went through some very deep water and the sensor worked fine. Still works fine. This bike computer stands up to the elements well.

    During initial setup, I had to reset the batteries in order to redo the settings -- which I messed up the first time. After resetting the batteries (required if you need to change settings such as tire circumference), the unit would not start and prompt me to redo settings. It was completely dead.

    The unit itself looked nice enough but very disappointed the quality wasn't there. I've decided to try a more expensive model and send this one back rather than roll the dice with another one of these units.
