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

It is a little difficult to set up but happy with the product.

The hardware functions very well for the price, but the software is poorly designed.Most importantly, it undercounts the Σ, your overall total. Here's an example:Say you have a Σ of 1400 miles and you go for a 20.9 mile ride on Saturday, raising your Σ to 1420 miles. On Sunday, if you go for a 20.5 mile ride, your Σ will be only 1440 miles.In other words, it ignores any tenths of miles each time you reset the daily tripometer. It took me a year to realize this. I ride about 100 miles a week, and after going back to look at my log, I've discovered I rode 177 more miles than the Σ odometer indicates.If you're a rider who rides to exercise, and you have an itch for accurate bookkeeping, do not buy this odometer.

Easy to read display, mounted on bicycle

worked as expected. Hope i received better and clearer instructions.

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.

Este velocímetro y odómetro para bicicleta cumple con su función: mide bien la velocidad, la distancia recorrida y otros datos básicos. Es fácil de instalar y hasta ahora ha funcionado sin problemas. Sin embargo, la pantalla es bastante pequeña, lo que dificulta ver los números con claridad mientras uno va pedaleando, especialmente si hay mucha luz. Aun así, por el precio, es una buena opción si no te molesta el tamaño de la pantalla.

Works well I bought it because it was wireless

Might be fine if it were going onto the front forks. But considering we're putting it on the rear for a trainer's use, it won't pick up the results of the sensor on the handlebars. Apparently, it needs to be VERY close to the sensors in order to actually pick them up. Didn't try it on the front forks, but my guess is that if you were using it on front wheel and mounting on handlebars as instructions say, it would be able to pick up the sensors. I can't comment much on the rest of the features or how accurate they are, since I didn't put it where recommended.
