I had my AUS implanted 5 years ago tomorrow and my dr she said that the cuff below the scrotum in the perineum is where the pressure will be . on the cuff. when you sit on a bicycle seat or motorcycle seat and not to do it. She wasn’t concerned about pressure on the pump in scrotum . So I have heard that some guys will get special seat to ride bikes to keep less pressure on cuff around the urethra.. My dr said no to bicycle or motorcycle so I sold them . Good luck..
