ROCKBROS GPS Bike Computer with Mount, Accurate Bike Speedometer with Automatic Backlight, Bicycle Odometer IPX6 Waterproof and 600mAH Battery Large Display Screen

I dont have much experience cycling but i was looking for a cheap and easy installation option for my go kart. it mounted simply to the roll cage and once the gps signal is up it works flawlessly. sure there are a few unneeded features when using it for my purposes but it sure beats the cost and time associated with other speedo options. i have left this out in the rain and its been covered in mud on more than one occasion and just keeps on running. simple but gets the job done!

This gives me the speed, distance, and time, in big easy to read numbers. It works on GPS, so with extra mounts, every bike I own uses this same computer. Not really easy to set-up. It could use better (maybe online) directions. But it WORKS.

Consider your handlebars and bike frame. If it is made of carbon fiber, it might not be made of round tubes. If the tubes are oblong (not round but more like you squished a pipe to begin to flatten it) your tubes are likely too large for this to fit well. You may still be able to Frankenstein it together.Regarding the "arm" mount (accessory), you'll never get that mounted. Even when just mounting the speedo device straight onto handlebars with the elastics, you can't "cross" them as they instruct. It won't work. If the little nubs were slightly different it might work but they're not and it doesn't. It will just fall off. Non-criss-crossed works but it's not really a fit I'd call "tight," but adequate, and then that might only work in the very middle of your handlebars. It's as if they never tried mounting this thing on a high end bike.As far as functionality, the buttons are VERY wonky. Maybe due to rainproofing, the rubber buttons (two) on the side sometimes work, sometimes not. It's almost impossible to turn off, but it is possible, based on "touching" the button just right. Instructions are poor but you should be able to change it to miles, as it ships set to kilometers and meters.With such a small, simple device, this company wins the award for having done just about everything possible wrong. Still, considering the low price, if you can get it mounted on a non-round-tube frame, it's a cool item. Does not require any wiring outside the bike. Slightly recommended for that reason, as it is a unique item. Once again, the guys and gals out there riding bikes that don't have wires showing are the same people who don't have round-tube frames. It's a mystery, and a shame.

The menus to set up the unit are not intuitive or easy I just wanted to show speed and distance and start of the workout, and it took me 20 minutes to reset the unit and start over. Ended up using the activity Application on my iWatch to track speed, distance and time

Works great and looks good on my bike . The bracket is very nice too . Picks up signals fast and is accurate . The best part is no wires to get in the way .

I got this for my son to put it on his bicycle. He absolutely lives it! He like knowing how fast he's going and he's always trying to beat his best speed. He also likes knowing the distance he has went. It was also so easy to install. All we had to do is simply install it onto his handlebars and that's it! Nothing else to put on, no wires to hook up or anything else at all! I am definitely satisfied with my choice!

This product comes with about the worst instructions for mounting on your bike. Seriously! Firstly, to mount stuff on a bike with rubber bands is .. well .. The mounting bracket does come with the product so you can avoid the rubber bands but it has problems too. It is much too big for a normal bike handlebar and you have to mount it closer to the center if you don't want it to spin around by itself. If you do not want the unit to be several inches off the handlebar you are stuck with the lovely rubber bands. If you are willing to use the bracket you will have to figure out just how to put it together which may not be rocket science but some pictures or notes would have surely made life easier.After fully charging the unit I put the bike outside (where it can get a GPS reading). Took about 1 minute 20 seconds to lock on the GPS. A brief test of the unit while riding the bike seemed fine although I did not try to match it to my phone's speed and distance reading. It is not crucial if the readings are off a small amount when it comes to leisure biking.I do prefer the display of this unit which, to my brain, seems intuitive and easy to read at a glance. Still not happy about the instructions and the 'rubber bands' but hopefully this will be the little computer that could ...

It does not have the bells and whistles of really expensive cycling head-units, but if you want time, speed and mileage recorded via GPS for a cheap price buy this one
