You are quite right Robbie. I think Peter's got himself confused because 25kph = 15.5mph.
My Kalkoff cuts the power assistance at 25kph / 15.5 mph, but that's fine because by the time you are doing that speed you don't need it anyway. I think most people possibly don't get what peddles are all about - it's not about going faster, it's not about putting in less effort, it's about enabling you to do things that you wouldn't normally be able to do - like going up steep hills or carrying heavy loads.
