Bike Computer with Solar Energy Bicycle Speedometer and Odometer Wireless Waterproof Cycling Computer LCD Backlight Automatic Wake-up & Multi-Functions

I followed the video instructions and the enclosed paper instructions and within 10 minutes it was mounted and fully functional. I need to adjust the wheel circumference value because it is yielding data rates slightly higher than my GPS tracking through my FIT-BIT app. I physically measured the circumference wheel traversal distance by rolling the bike until the tire valve completed one full revolution on the floor. The display can be fixed or set to scroll through them all while you are riding. The screen was clear and highly visible. The wireless spoke transmitter seems to work like a charm with no data drop-outs or false data being shown at any time during my inaugural 55 minute bike ride. I am fully satisfied and quite impressed by this and it was very reasonably priced. Thanks for a wonderful product.

Not a bad product. Came with a monitor, two sensors. One sensor (which is magnetic) fits on the spokes of the bike. The other fits where ever you can attach it to. Just a word of warning you need to make sure that when these two sensors pass each other that they are relatively close to each other (as stated in the installer's instructions). The biggest difficulty finding a position on the bike for the larger sensor. The plus side is that the manufacturer provides some zip ties to help with this. The monitor was very easy to figure out and easy to set the settings. It reads accurate results from what i can tell from eye ballings the progress. Besides installing it, its a pretty good monitor for the money that was spent.

Another edit/update --- Outstanding Customer Service!! I contacted the seller and described the problem my unit was experiencing and they very quickly honored their warranty and solved my problem. I am back on the road and VERY happy with my purchase again!!Edit -- 9 months later . . .I still really like this bike computer. Unfortunately after 9 months, it has lost its mind. Suddenly it is reporting distance about 8% above actual distance. I double checked the wheel circumference setting and it is correct. I have been unable to find any warranty information at all. I plan to order another one and cross my fingers for a longer life this time. That's how much I like the computer. I'm leaving my rating at 5 stars for now.My ebike display only shows trip mileage in whole mile increments (!!) So I went looking for a simple bike computer that would let me know exactly the mileage of my trips. I tried several and most were unreliable or the display was not clear enough or it took an advanced degree to remember the button push combination to see information.Once I found this computer, my search was over. The display is easy to read. It is easy to install. It is accurate -- provided you input your tire size correctly. Granted it has some features that whose value is questionable (calories consumed ... really??) but they don't get in the way of good useful information such as speed, and travel distance. This computer adds to my biking enjoyment and it is very budget friendly.

There is no parts list with the instructions.The parts pictured in the instruction illustrations are not detailed enough to get them installed correctly."Tool free assembly" notation hardly offsets the inability to assemble the product correctly, due to the headline above.EXAMPLE: under the highlight "Setting steps", instruction #2:"KM/M selectable. Screen shows KM, press right button to change to M or KM and press left button to confirm, setting from right to left."There are only 2 buttons on this product to control/change 22 different functions! I purchased 2 of these units for 2 different bicycles, and, when I followed the above directions, I was unable to get either unit to change from kilometers to miles.I could go on to list the obvious by referencing the 9 other impossible-to-understand paragraphs in the instructions, and the problems I had trying to follow them, but by now, you should get the idea that you need to select a DIFFERENT bike computer from a different supplier. Please.I am requesting a refund. Enough said.

I have a recumbent bike and unless I have the handlebars at just the right spot, the receiver won't pick up the signal. My old unit didn't have any problems with this, but it decided to stop working on me...Setup was easy enough, but the mounting bracket for the receiver is so thin that it already cracked because I bumped it. If it wasn't so cheap, I would have given it two stars...

Excellent design and performance.I would purchase this product again.

I just purchased my third. One was on a bike that was stolen but I have it on a road bike and a mountain bike. You have read people's frustration and the 1 stars are probably mostly from that. Mountain bikes pose a unique issue in that you will have to tilt in the sensor on your fork to get it close enough to register. It will not point straight ahead like on a road bike because the large diameter of the fork and spacing with the larger tires.One caveat, this as are almost all lcd screen bike computers, is tough to see in daylight if you wear polarized sunglasses. Accuracy is very good. I laid both out in the sun and it got hot (80 degrees) and it turned the screens black. Thought I had killed them both, but after three minutes in the fridge to bring them back down, both patients are healthy and functioning.
