ROCKBROSBike Computer Wireless Cycling Computers ANT+ Bluetooth Bicycle Computer Mini Speedometer Odometer Waterproof 2.9inch LCD Screen GPS/BDS/Galileo Position System

I was very impressed with this odometer. At just $45 it was ten times less expensive than a Garmin device that I bought six years ago. It has all the same functions and even a couple more. I am very impressed with the battery life. It's been lasting me about ten days, and I ride over an hour a day. I was afraid it was not compatible with the Garmin website, but I mereley export the GPX file from the Strava website so that I can import my activity to Garmin. The only function that I miss is a real time display of my average speed. I use that feature mostly. With this device, it only tells you the average at that moment. You have to keep going back to it to get an update. But I am pleased that the display is almost twice as large as one of my Garmin devices. See photo.

What I like the most is the light. Living in Vegas if you don't get up at 03 or 04 you will become a heat injury and the light is great prior to sunrise.I found it easy to set up and very accurate in its speed, distance and elevation calculations/readout.Great battery life and a nice big screen to boot!The out front mount is very durable and I purchased the heart rate monitor as well and it makes me feel like Iron Man a little bit (though my speed does not reflect that feeling sadly).Overall much more data than my previous computer and everything I wanted.Cadence and wattage is available as well, but I'm no pro so I don't need that data as far as I know.A "Hit" in my book and well worth the price!

The device is probably the nicest looking one I've see, but . . .The factory is working with me to hopefully resolve these issues. I use it on my mountain bike outdoors. This is the second one that will not show distance and time traveled. I have not even checked the other features other than speed which seems to be accurate (based on the GPS tracking).If anyone has experienced this same issue please reply. I have programmed the device per the instructions (twice) and wonder if I'm doing anything wrong. Is there a way to get the distance and time to start recording?

the product was very difficult to get to work, instructions were a challenge and the product appeared to be made by a company not familiar with cycling . I eventually purchased another brand with no issues at all.

Bought to replace a Wahoo ELEMNT Bolt that broke at its charging port and now longer powers up. At one tenth of the cost of the Wahoo, it's a bargain for sure. I was never happy with the Wahoos mapping functionality (basically you need an App - Strava or Kamoot to load a route to it from a computer or phone) so I rarely pre-planned mapped routes anyway. This ROCKBROS computer gives all the functionality that I relied on the Wahoo for - Speed, distance/duration of ride, Time of day, ambient temperature, connection status, battery life, lap counter, altitude, grade, total miles ridden Odometer, cadence (if you have added +ant sensor). Another positive, the battery life of the unit is MUCH better than with the Wahoo. Wahoo would have to charge after each ride day. This ROCKBRO unit lasts weeks at a time of daily riding! The included mounting system, lock ring mount with heavy duty rubber bands holds well and can be affixed in customizable ways (I put it over the top of the Wahoo mount. Also the computer unit comes in a rubberized protective sleeve that fits around the outside edges of the unit.Two negatives: 1) I believe it is run off of the BeiDou (Chinese) satellite constellation and coverage seems spotty at times. It will occasionally not pick up signal from the sky and show erroneous or no speed data. 2) The size and position of the text readouts is fixed and not adjustable. With my tired old eyes on a moving bike, I cant read certain fields. Pretty pleased with it though, overall.

Large screen, easy use functions and reliable. Had it for 3 rides so far without issues.

Good article for the price

Using the HANDLEBAR RUBBER BAND mount, my first ride with this bike resulted in it being knocked off 2-3 times (once at speed when tapped by my knee, twice when laying the bike down to rest.)I was going to return it, but Rock Bros asked me to try the front mount.IT IS NIGHT AND DAY. The front mount is rock solid. WHY do they even sell this without it?Great support and I love it now.
