What do you need to hook up a body rider?

There is a moofit speed and cadence sensor with ant+ on Amazon for $40. Would that work with a bodyrider dual trainer?

That is unsupported to use with Zwift. If you can mount a speed sensor (that is a big if since it has a fan instead of a wheel) on it you can get your avatar to move within Zwift, but your speeds are not going to be correct. Zwift does not have a power curve for the “trainer”.
