Yes there's an optical encoder on the other end of the motor.
Depending on the pressure of the roller on the cassette drive wheel it
will deform more or less.
That effectivley changes the diameter and hence the speed. So you need
to set it.
Its a DC motor so you can control the speed.
Just count the encoder pulses over time and you know what the speed is.
Did you glue your pressure hose on or was a push fit enough?
I think I may have glued them, but I am not sure - I do recall that the
fit was pretty tight.

pressure from Home Depot (here in the US), and then sanded it down to a
reasonable O.D. size (IIRC). Worked great.
I don't know that the diameter is absolutely critical - I think it has
some kind of speed encoding.
