What is the cruising speed and max speed?

StreetStriding speed depends on how fast the user can rotate the foot platforms, their cadence.  StreetStrider models have gear ratios that give the user very similar speeds in the highest gears.  For comparison purposes, if the user is striding at a cadence of 60 rpm, on the 3i in 3rd gear or the 7i in 7th gear, they will be traveling at about 20 mph.  Of course, as the cadence and or selected gear is changed so will the striding speed.
