ROCKBROS Bike Computer Wireless Cycling Computers ANT+ Bluetooth Bike Speedometer Odometer Bicycle Computer with Speed Cadence Sensor for Riding Cycling Waterproof 2.9inch LCD Screen

End of Jan 2026 - note I've only gotten a couple rides on this so far - the bracket works perfectly (no real instructions come with it) - the sensor works great (haven't tried speed, just cadence) - the little computer is good, screen easy to read - paired with the app, lots of good data is available to review - computer connects with the sensor no problem - computer connects with the app no problem I can't yet comment on battery life for either the sensor or computer

Update: 1 year later. Having issues with gps connectivity. Takes about 10 minutes to connect. Ill start my ride with nothing reading. Eventually ill see some readings and then ill start my recording but by then total mileage and time are inaccurate. Battery still lasts as long. The display is clear for day and night use. The screen is always lit. It is bluetooth so it can connect to your phone and strava. Only difference is it will not show your heart rate and calories burned when logging in data to strava. Setting up was a bit difficult. I used youtube to help. But once you get it down its as accurate as it can get. As far as accuracy. The mph is off just slightly but not too much. Example: apple watch says 15 mph and computer shows 14.7 mph. Distance travelled apple watch shows 30 miles traveled, computer showed 29.1 miles traveled. So cant complain

Have only gone through the set-up, and the installation on the bike--instructions on the former are not ideal but good enough and set-up was fairly minimal and smooth, while there were no instructions for the latter but it was sufficiently simple and intuitive that it also went smoothly. Downloading and syncing with the XOSS app on my phone went well too. Will be using it on the road for the first time tomorrow, looks like it should be a good experience--large display, good info, very firm install on bike handlebar, etc.

This glitches and gives inaccurate distance, speed, elevation. It's just bad.

Not a bad system but I’m puzzled by something: Why, if the GPS is used for speed, doesn’t it also use the GPS for ‘distance’? The system requires you to enter the circumference of your tire in order to track the distance that you’ve ridden like older odometers. Also, I found that the chart states that I should program 2268 MM into the unit. When I do this - and check distance with the GPS on my Apple watch - i find that the mileage is high by about 3%. If I change it to 2200 MM the mileage matches just about exactly. Also, there is a fairly steep learning curve regarding ‘setup’ especially regarding the clock setting - eventually you’ll figure it out but it’s not spelled out very well. Functionally, though, once it’s all set up, it’s a usable, useful device.

The GPS works well and only takes a few seconds to geolocate. The unit easily connected to my bike for power and cadence. It also connected easily to my Schosche heart rate monitor. The screen is LCD and is very legible in bright sunlight. Many of the icons (GPS lock, time of day, temperature, battery level) are very small and more suited to younger eyes. The left button has three uses, on, trip start and long press for off. The screen has a backlight that is only on momentarily. After turning on you must press the left button again to start recording today's ride. You know the trip is activated by the trip time showing 1 second and holding until you start riding. The trip time is only the moving time. The right hand button toggles between prescribed pages. There are three NOW pages that show various aspects of the current ride. There is an AVERAGE page and a MAX page then the circle repeats. None of the fields can be changed to other pages. Charging is USB-C. Removing the rubber cover over the charging port is a little cumbersome. I used the direct handlebar mount rather than the handlebar extended mount. I ride rough terrain and it works well this way. GPS connects quickly. ANT connections worked easily. Seems like a good unit after a month of use. Love the USB-C port, I don't have to hunt other cords to charge. I recommend without reservation.

I can't seem to get the clock set to the right time.

Really great deal on a super nice bike computer. Easy to setup and configure. And great customer support. Highly recommend!
