Review: Great Value,works well - This is my first bicycle computer so I cannot compare it, but I like it very much for what it does. To have bicycle speed,average speed,odometer,trip meter,temperature and time on display is a benefit to cycling. All that for the price is good value. It does take a bit of time to figure out how it works. Install was straightforward. After install I was curious as to the accuracy of the device. As I found out,this all depends on the number you enter for your tire circumference in millimeters. Initially I used the included chart. Where I ride there are milage markers and mine was off about 50 ft per mile. This was too much for me. I rode 7 miles with a 350 foot error. Here is how I fixed it to bring the accuracy within the resolution of the device which is approx. 5 ft/mile. Find a flat surface and lay a tape measure down for 25 feet or so. Using a piece of chalk mark the tire and the surface you are rolling on as zero. Then carefully count the rotations of the tire,I did 3. Take that liner measurement along the ground surface and divide it by the number of rotations to get your actual circumference of your tire. The more rotations and longer the distance the more accurate you will be. If you measured in inches, then convert it to millimeters. Round it to the nearest whole number and enter this into the device. This worked great for me.
Review: Easy to use and fairly accurate - Works great to track distance and speed. Regularly use this on bike rides to track how far I've gone, average/max speed. I used this in conjunction with my phone GPS and it's fairly consistent.

### ⭐⭐⭐⭐⭐ I like it so much I bought another one.
*by S***K on April 23, 2025*

I bought an ebike early in 2023 that came with a very simple controller, no display. I absolutely love this meter. I use it on SCAN so I can see Trip miles, Trip time, Avg Speed and Max Speed scrolling at about 2 sec intervals. I bought another ebike for $200 more than a new battery and motor would have cost for the old one. I still ride the old one for a few reasons, so I don't want to remove the meter. The new bike came with a large display, but no scan function, and seeing top speed and average speed is a real pain in the neck. It takes me 3 tries to reset the trip meter. This one's a no brainer. The older bike has ~3,000 miles on it, and it and the meter are on their 3rd year. I have had no issues at all with this meter. As far as battery life it lasted 2 full years. It's a simple install, and if you really want to be completely accurate there are instructions on how to measure tire travel and set it precisely. For my use I just entered the circumference of the wheel in centimeters, and according to my car it's spot on. One nice function is temperature, although it seems a bit "ambitious" as it's usually 1.5 degrees higher. No biggie. Connecting it to the bike is easy, and since it's wired it doesn't drop out like a couple of wireless models I've tried. I did manage to lose the magnet, but bought 2 all metal magnets for $8 and there were no issues. I wanted to get one for a non-ebike i bought last year, but they were sold out so I put another that was double the price i bought originally on it. It also has a scan function, but is less informative and harder to read. I was very happy to see they are back in stock. For such a good price it's a really good meter and accurate. One note on changing the battery: write down the ODO mileage, since when you remove the battery there's no "hold up" function and you have to re-enter total mileage. It's noted in the instructions, and it's not a big deal. Oh, and it also displays an icon of a wrench to let you know it's time to oil the chain and tighten the spokes. There is also an Up and Down arrow to let you know if you're above or below your average speed. All of this for a very reasonable price.
