How could I upgrade my Schwinn Airdyne exercise bike from a mechanical load indicator (speedometer) to an electronic display?

There were two electronic display options that required additional parts to convert the Schwinn Airdyne 3 and Airdyne 4 exercise bikes from the mechanical speedometer to the electronic display.

Option #1

Many of these parts are no longer supported by the OEM (Original Equipment Manufacturer). If we no longer have the part and do not offer a substitute; We do not have a recommendation of where to buy it.
