What speedometer code for 26 inch wheel on bike?

Answer 1

You have to measure the wheels outer circumference, in mm's, then enter that number into the speedometer.

1. Place a strip of tape on the ground, draw a line on it.

2. Place the wheel over the line, align the wheels inner-tube valve with that line.

3. Roll the wheel one complete revolution, mark that spot under the inner-tube valve onto another strip of tape, and measure the distance between those two lines on each strip of tape.
