Schwinn 12 Function Bicycle Computer : Target
I bought that exact speedo from walmart. It has worked flawlessly for 1500 miles
with a 4 stroke motor.
The speed is accurate too as checked against a GPS. You have to measure the
diameter of your wheel to get your speed correct.
My 26" x 2.25 front cruiser tire measured 26.5" and there is a chart in the instruction
booklet giving the mm number to enter into the speedo.
It will be 100% accurate if the diameter is correct as all it is doing is counting revolutions
of the wheel.
I have not tried one with a Chinese 2 stroke, you may have to get a resister plug and wire
but seeing that it is wired you may not have a problem with interference.
