The Science of Bicycling

I was looking around on Google and came across the link below, lots of both technical and non technical information. Things both the Newbie and exprienced rider can learn:

Hmm - I like that little calculator that tells you how fast you would be going if the headwind wasn't there...

That's an awsome site. We nerds thank you. It's good to have numbers and references when in a conversation about biking.

Nice site but I disagree with a few things such as this: "recumbents are harder to see on the road--most use an orange safety flag so automobile drivers can more easily avoid them."

Few people use flags afound here.

Damn I wish I would have seen this site for a Physics project I had to do, I would have blown all those other projects out of the water. Great site though, some stuff on there really never thought about. Seems like you can apply science to almost anything nowadays.

hmm, you didn't happen to see that low recumbent just go flying by you did you? I don't see any recumbent here. Do you? No orange flag........nope I just can't see him. He's gonna get run over.


The cars not being able to see you is just plain BS.

Now I do agree though that the biker wearing the bright yellow is way more likely to be seen. My next racing tailfairing will have bright yellow on the rear like what this guy is wearing.

This was a pic a buddy took of me on the hilly hundred. He was following on his lowracer. Pretty good shot if ya ask me since we were both doing well over 32mph at the time.......passing the upright guys doing maybe 19mph by my estimates. Going these speeds, I'm also in front of cars for a longer period of time, so it probably gives the driver more time to see me.
10,000 miles on the road now in one of these and never had a driver tell me I couldn't be seen. They have stopped me plenty of times though to ask questions or just plain gawk at it.

That site was ok, but not very useful as far as wattage and speed models go. The best on the net so far is this site. At this site, you can figure out what speed you can actually go on negative or postive grades and wind speeds.

http://www.kreuzotter.de/english/espeed.htm

This is an online calculator. You can compare your speed difference in the same conditions if you were on a mountain bike, various types of road bikes and recumbents.

You can input either wattage or speed to find either or.

That site is obviously done by a roadie. The give away was the varrying wheel sizes he offers to calculate . Would have been interesting to see how it works for my situation (any of my bikes)

To bad, I like to play with numbers sometimes

You obviously didn't look at the site very well. You also don't know much about recumbents. I don't see how you came to figure that a roadie created this site. He is in fact a recumbent rider.

Do you even understand what you do on this online calculator?
