usfull place to put the magnet on but i still need to no the wheel factor whatever the hell that is

the wheel factor is simply the diameter of the wheel in mm X 3.1416 so a 16" wheel X 25.4mm = 406.4mm X 3.1416 = 1276.75 or rounded up your wheel factor or circumference is 1277 enter that, but you can use a satnav with speed reading to double check and the speedo can be fine tuned by altering this figure, hope this helps

Sorry meant to add, if you want to fit the sensor to the front wheel as its easier to get to, the wheel factor is 958 for a 12"wheel
