Bike computer wheel size calculator.

Using a bicycle computer on a scooter or go kart. Given rim diameter the iso diameter and tire diameter the size of your tire converted to millimeters wheel diameter rim diameter tire diameter 2. To get the approximate diameter of the wheel with the tire on you would take the diameter of tire x 2 because it s both on the top and bottom the diameter at the rim pi 3 14 to get the cimcuference. An accurate speed sensor can also improve the accuracy of gps bike computers like the elemnt elemnt roam and elemnt bolt especially in tree cover or near buildings.

Multiply this by pi 3 142 to get the circumference in mm 2130. Appropriate calculations will yield calibration numbers for computers in other groups. Input this number as the wheel size in your sigma computer. Lay the millimeter tape on the ground.

To get an approximate diameter in mm add the bead seat diameter to twice the tire width since the tire depth comes into the diameter twice. Calculate your result by 2 54 to get centimeters and 25 4 to get millimeters if your tape measure uses inches. A bicycle computer can be used on an electric scooter or go kart if the correct wheel size is programmed into it.
