Hi

Just found an easy and cheap way to measure rpm.
Get a bike speedometer + a second magnet.
Mount the magnets and sensor.
Set the wheel diameter to 833.
Set it to show Km/h.
Reading: 10.5 Km/h =105 rpm
14.8 Km/h =148 rpm .........

Good idea you can use 268 for mph which should give 0.6 = 60rpm.
