You epoxy or JB-Weld a magnet to the inside of the front rim then attach the sensor off your spindle with a homemade bracket. Once installed, you will measure the distance of one full revolution of the front tire in millimeters and input the this value into the bicycle speedometer calibration screen. For reference: 20" tires are about 1600mm circumference, 21" are 1675mm, and 22" are 1750mm.

How about somthing like this?
