wrong sorry
one rev of the back wheel will move the bike down the road the circumference of the tyre, on a 17inch rear wheel approx 1.88meters
the gear box is connected to the rear wheel by the sprockets, they haven't changed
the gearbox is connected to the crank by the clutch, as long as that isn't slipping then that hasn't changed
the crank will spin at any speed you want dependent of your wrist
BUT
ONE REVOLUTION OF THE CRANK WILL MOVE THE BIKE A SET ANOUNT OF DISTANCE DEPENDING ON THE GEAR RATIO, you could change the filter, fuel ratio or even push the bloody thing down the road but the rev/speed ratio will never change, it is literally set in steel
