# How many watts?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Also keep in mind that G = (6.67428۪ ± 0.00067)(10^-11)(m^3)( kg^-1)(s^-2), although it is a bit dated.

I don't look like Lance, so you will be unable to drop me.

Here's a pretty good calculator if you put in all the right numbers https://www.gribble.org/cycling/power_v_speed.html

From this 2005 thread: I am sorry I have to drop you because you look like Lance
I was comutting to work yesterday and passing through Prospect Park. There was a guy who looked like Lance fully decked out with a Trek and Team Discovery outfit. Even his helmet straps were yellow. He was on his 53 x 20 or 19. I knew it wasn't him (not surprised) because he was only slightly faster that I was. I was on my 39 x 14 and just spinning away. I caught up to him near the foot of a .25 mile 5% climb. As I rode ahead of him and noticed the color of his helmet straps and I was determined to teach him a lesson. We both approached to the foot of the climb and I was determined not to change gear. I have my power output set to 400w. roughly 19 mph. I glanced back at him and to initiate the challenge. He took the bait. He was slowly closing in to my wheel. I stood up and dropped down to my 13th gear and just blasted it up at 19 mph. Unless he has been racing, there is no way he could match my speed.
