very interesting listning to this debate.It does take Hp to do 150MPH but know one knows exactly how much. We all have driven a bicycle and each person only has X amount of Hp.When we drove single speed bikes some had big tires some had small,different gear ratios we could choose the fastest bike or the fastest take off bike.Then came the 5 speed 10 speed WHY? because it allowed you to get there faster with still the same person or HP.NOw we could speed up quickly and shift up till we were at the fastest speed we could get to.It took no more power to start than to finish(at least not that your body could feel)at the start you did 5MPH at the end you were doing 15-20maybe 25 MPH. You could never do that speed with a older low geared bike.YOu still had the same power but not the right gears to propell you to a faster speed.I think a bicycle is a way better way to show the diffrence that a single HP can do than say run a big rig with a 15 hp motor.I as a human can only produce so much power and when I started into the 18 speed bikes I know they uped my speed by a good notch and it wasn't because I gained power over night.

so all you who don't beleive a certain Hp can get a car of said weight to a certain speed you DO NOT KNOW HOW MUCH Hp THE DRAG, WIND RECISTANS FRICTION and all those other ghosts that hold back the car takes.until you sit in the drivers seat at that speed get of your a$$ and find a biycle and see how fast you can get in each gear and then come back here and let us all know what you found out about GEARS.
