I put it on a fold-up bike and it tracks my distance and mileage and speed and has the time too. I am glad that I can log my rides and try and improve. Review: A Very Good Buy. - The whole system is weather resistant and durable. Just make sure you don't lose the O-ring that is used to seal the computer when you install its battery. I suppose the same might be true for the sensor itself although I may have already lost that O-ring. When calibrating the system, the manual has a chart that you can use for different wheel sizes. It also suggests measuring the actual circumference of your wheel. I highly recommend measuring the circumference, as the accuracy was spot-on for me when I did it. Also, my wheel size was a teeny bit larger than any entry on the chart. The computer itself, being wireless is easily detachable and small enough to put in a pocket. I strongly recommend doing that unless you stop or park in highly secure areas. That was how I lost my previous bike computer, within 2 weeks. ## Features - 【Auto Wake-up Function】Automatically wakes from sleep mode upon sensing vibration in the bicycle.

Is it difficult to install** A: No, it is very easy to install it.From good friend M.Reed , you can know this 3 steps.There are three parts. Installation is very easy and just takes a few minutes.1;The magnet is mounted onto two spokes on the front wheel - using the built-in thumb screw. 2;The transmitter mounts to the front fork next to the magnet - it's attached to the front fork by two supplied wire ties. 3;The receiver clamps onto the handle bar using two supplied wire ties. To neaten it up, I trimmed off the excess wire tie ends using a wire cutter. Scissors or nail cutters will work if you don't have a wire cutter. 4;Since this is wireless, there is no cable required. 5; You program it to the size of your wheel, mph or kph, etc. **Q: I have a terratrike and need to mount the sensors on the rear wheel. will that work? also, have the smaller tire version. can i calibrate for that?** A: I have this working with the sensor on my rear wheel, but I had to move to computer from my front handle bars to underneath the seat on the frame. I can check my speed/mileage by looking down, but it isn't easy like glancing down at the handlebar. This isn't ideal, but it's fine because I'm on a stationary bike. I will move it to the front wheel when I return to biking outdoors. **Q: Can you display the odometer and speedometer at the same time or do you have to cycle through them?** A: Yes, the speed and odometer do display at the same time. In fact, the screen shown in the ad shows the speed as the larger number and the odometer as the smaller numbers at the bottom of the display. **Q: speedometer stays a 0 when doing test and canot set clock?** A: Mine did the same until I accidentally found out that the sensor also requires a battery. Slid the cover back on the sensor and turn it over and a round piece falls out. That is where you put the battery. For whatever reason that is not noted in the instructions ## Customer Reviews ### ⭐⭐⭐⭐⭐ I like the options *by P***S on August 15, 2026* Easy to set up and install and the options are fun.

I wouldn't buy this again. *by T***Y on June 13, 2021* 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. ## Frequently Bought Together - YS SY Bicycle Speedometer and Odometer Wireless Waterproof Cycle Bike Computer with LCD Display & Multi-Functions - Lamicall Bike Phone Holder, Motorcycle Mount - Motorcycle Phone Holder, Handlebar Cell Phone Clamp, Scooter Phone Clip for iPhone 16 Pro Max/Plus, 15 Pro Max, S10, S20, More 4.7" to 6.8" Smartphones - Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/36008756-bicycle-speedometer-and-odometer-wireless-waterproof-cycle-bike-computer-lcd](https://www.desertcart.co.th/products/36008756-bicycle-speedometer-and-odometer-wireless-waterproof-cycle-bike-computer-lcd) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-17*
