Hello, this is my first post.
I've bought a bike computer, I don't know how to set up the speed, odometer, etc.
I have four numbers, form 0000 to 3999, I guess I have to input the cm or inches or something, when I change that number it changes the speed, etc. I.E, oooo, no speed, 3999 shows like 40 km/hs with a single revolution.
It is an unknown trade mark ( Jingyi ( a cheap one ))
Just now I set up a 3999, because is nice going at a fast speed and I've ride like 100km in one single day
Warm regards,
tristan
