I am not in sales...I just do this for entertainment.

You should check the actual speed with a GPS or with a friend in a car. Also most of the Chinese speedos are off usually more generous, also your size affects top speed.

Count the teeth rear/front. 45/17= 2.65 which would be more for top end speed, here is a chart.
