Review on 🚴 Serfas SI-40 Level 4 Wireless Computer: Revolutionizing Cycling Performance by Mark Erandio

Resetting the mileage is non-intuitive. Doesn't even follow the instructions given to him. Holding the "A” button for 5 seconds will reset the 3 second hold – wheel size and odometer reset. Other than restarting the entire computer, I haven't found a way to reset the average speed. I chose this one because it shows you the temperature - I think it's a feature I can do without. Agree with the other reviewer on 2 bike settings - a sensor is kind of a useless feature unless you're sold additional hardware for ease of use.
