I have reached 70km/h with a 20" Dahon with SRAM DualDrive, a 52t chainring and 11t sprocket. It has a higher gearing than most road bikes.
Sorry my friend, but its not true.
To archieve that speed with that gearing you shoulb be pedaling at 160 rpm cadence, witch is hight doubtfull.
You can check calculations in
BikeCalc.com - Speed at all Cadences for any Gear and Wheel.
