Review on YS Wireless Waterproof Bicycle Speedometer & Odometer With LCD Display & Multi-Functions - Track Your Ride! by Patrick Keita

Super easy to install just follow the directions. I’m very happy with this odometer, for the price it is everything you could ask for. It takes about five minutes to set it up and it attaches well to your bike. I found the distance to be fairly accurate when compared to my phone apps. I would say if you have a bigger bike it’s a little tricky to get the sensor within 3mm of the magnet. I have a specialized rockhopper size medium with 29ers and had to wiggle it to make sure they come into contact. Overall though a great entry level piece of gear.
