Review on 🚴 DINOKA Waterproof Wireless Bicycle Bike Computer with Speedometer, Odometer, and LCD Backlight Display – Multi-Function Cycling Companion by Rey Hossain

I had a 20 inch wired speedometer for my sons and it didn't last long, the wire just broke when he turned the wheel. wire and this one was perfect. It was very easy to install. The hardest part was placing the magnet and gauge at the right angle and distance for the speedometer to get a reading and once you have it installed use the zip to tighten it and you're done. Use my picture as a guide to see how far to place the small magnet and at what angle to set the sensor to get a reading. Make sure you set the correct tire size to start with, this is a 4 digit number that you can find in the manual.
