Help

Calculate the ratio of your bike: K = 10 * X /U
U is the circumference of the wheel causing the meter. You can calculate the formula of the perimeter of a circle: 2 *π* radius of the wheel in cm
X. = the number of turns that is the square driving the speedometer 10 laps. To count the number of turns, mark the cable on one side and spin the wheel 10 turns.
If K = 1, you need a speedometer K = 1.0 or an adjustable speedometer. (Example: the digital speedometer)
If K = 1.4you need a speedometerK = 1.4.
