It doesn't move much. Maybe 1/2" at the most. Can't remember. Bikes out in the shed. It just pushes the the clutch plate off of the clutch pads to allow the wheel to spin freely. Did you watch videos on installing. There could be a clutch adjustment needed. Maybe the clutch pads are stuck to the plate. There are some very knowledgeable people on here but without pictures or videos some things are hard to figure out.
