SY Bicycle Speedometer and Odometer Wireless Waterproof Cycle Bike Computer with LCD Display & Multi-Functions by YS

Great little addition to my bike ride!

Easy installation, works very well.

Update: After messing with this thing for several weeks I find it to be completely unreliable. It'll read great one day and the next day it will vary between showing zero MPH and 15 MPH. I don't know if the cell phone that I carry interferes with the wireless signal or what but this thing does not work well at all. What I wrote below was how I felt in the middle of my trials. The physical installation is not difficult - tie wraps and such. No big deal. What is difficult is working out the distances along with the particular configuration of your bike. The distance from the computer to the sensor is critical. You get beyond or even close to the 60cm distance from the computer to the sensor and you will get very erratic readings or no readings at all. Same with the 3mm distance between the sensor and magnet. 3mm is about 1/8 of an inch! I have a trail bike with wide forks. That presented an issue in getting the sensor close to the magnet AND also having the sensor not too far away from the computer. I had to try about 8 or 10 configurations where I finally ended up with the sensor tie wrapped on the INSIDE of the fork up close to the brakes (had to keep within the 60cm distance from sensor to computer) which allowed me to get the sensor and magnet within the 3mm distance as well. Once I got those distances happy and figured out how to mount the sensor in the wide fork spacing, everything worked great! Nice features on the computer and you can tune the wheel diameter to get the mileage distance more accurate.

Overall this cycle computer performs well and for the price it's a good value. There are just a few things that I would improve upon but I tend to be a little picky. 1) Mounting of both computer and wheel sensor is done using small wire ties. It would be great if there was some kind of a bracket with a screw that could be used to tighten it instead. I don't feel that I can really get it tight enough with the wire ties. 2) The Average speed value is unpredictable. If I'm moving along at a constant speed above the average the value should never drop. 3) I had a Bluetooth speaker mounted on my handlebar right next to this computer. When the speaker was on the computer wouldn't work at all. Clearly the Bluetooth radio signal was interfering with the wireless wheel sensor. This wasn't immediately obvious and until I figured it out, it just seemed like an intermittent problem. My other computer, (the one that this one replaced), was doing the same thing.

My father-in-law recently purchased an electric scooter and he wanted to know how fast he was moving up and down the sidewalk. At times he has a hard time installing small items like this but he didn’t have any issues doing it by himself. He said it’s been pretty accurate, and the battery life has been really good as well. Display size is good and he’s able to read and understand the screen. Good item for a part time speedster.

Simple to install........ but first rain and it quit working and fogged up. I asked for a replacement and they sent another. I decided to be safe to not leave it exposed to the rain when I get caught in rain. But as luck would have it the bike sat in the rain a few hours. New one tolerated the rain but I am still leary if it gets wet. Several other comments made about it fogging in the rain.

So easy to install. Took me about 10 minutes. Works great. Saw reviews on hard to see display. I can see my speed and milage extremely clear. For the money this is a no brainer.

The Speedometer was easy to set up and install. The large screen is easy to see without my reading glasses.

Easy to install, precise, all the required modes are there including current time. Automatic start/stop. Everything is included. Choice of colors is a plus too. Won't register speed or distance below 40°F, this is annoying! One day delivery.

The price that it was easy to install and was very straight forward to program. You must read and follow the instructions. I use it to mainly keep track of my speed and distance travelled. Also too I like that I can p program for KM or MILES per hour. Oh one other thing no wires, great.

Il est fait ce pour quoi il est conçu mais il consomme énormément la pile. La pile fait à peine 6 mois et pourtant le compteur n'est pas utilisé intensément...

Bought 2 of them and 1 wasn't accurate, got refund

It was relatively easy to install and works well. For me, the fact that it only works in the front wheel is an issue since I often use my bike mounted to the trainer indoors.
