On petrol machines it is usually done through impulses from the ignition or by the means of a sensor mounted to the wheel, drive shaft or ignition rotor.
In most cases there will be a magnetic sensor on the front wheel.
Put the thing on a milk crate or similar, turn the ignition on and spin the wheels by hand - if you see a speed you know where to find the sensor.

Usually an analog speedo is driven by a rotating cable off a gear on the front wheel, but if has no cable drive then its anybodies guess.
