I for one have no desire to have a power tap. The reading it gives me might make me cry.

Assuming the girl in front of you that you intend to pass and then smirk at is your signpost. Lets assume that she is wearing a white jersey if your relative velocity to hers is positive (meaning you are catching up with her), the wavelength of the light off her jersey will get shortened and shift towards blue (since blue has a shorter wavelenth). So if her jersey looks blue you are gaining on her.
If on the other hand, she if leaving you in the dust (meaning that your relative velocity is negative, the wavelength of the light off her jersey will be lengthened and will shift towards red (since red has a relatively longer wavelength). If her jersey looks red she is moving faster than you are.
From there, it is an easy matter to measure the amount of blue or red shift and determine at what velocity she is either moving towards you or away from you. It is then a simple matter of catching up with her (when she stops) and asking her how fast she was moving. You then take her velocity and add or substract the relative velocity to get your true velocity.
Of course if she is not wearing a white jersey the calculation gets a bit more complex. In any case you may need a spectroscope.
Or you could just get a bike computer.

I agree that none of the solutions are going to be inexpensive by normal standards. The PowerTap hub however at least looks hot.

It is quite simple. If you drop a good looking girl, you are going too fast. If the good looking girl drops you, you are going too slow. Everything else is irrelevant.

You guys may give me hell but my bike computer is going to be a handheld GPS I have that I also use on the motorcycle. It may look huge but it gives all kinds of crazy stats. And I can then do that Motion Based thing as well and NO WAY I can get lost..

For Watts, simply take the highest number you see posted in any number of threads here, add 10% and there you go.

don't discount the amish though. They hand make all their bikes, although they get the steel directly from reynolds. No composite wimpy frames for them. They're also hardcore as they only make fixies with a 53-11 setup and no brakes.

How much larger is your handheld GPS compared to something like the Garmin Edge 305? I don't really see a problem with using a handheld GPS if you can either stuff it in your jersey or zip tie it to the bike.

Then of course, after the technology has been fully exploited, which should be about version 6, I will be releasing the model in the team colors of the Amish Race Team. Corn Stalk Green and Wheat.

If you pass me, you're going fast.
If you pass Lance, you're going really fast.
If you pass Chuck Norris, you're dreaming. Nobody can pass Chuck Norris.

3 ways to tell how fast you are going:
1.) If all you can hear is the howl of the wind and your hearting beating in your ears, you are going fast.
2.) How bad are your eyes watering?
3.) How much skin is left on the road if you go down?

But who would want a powertap in the first place?! First of all they are quite heavy and second of all they aren't pin-point accurate. SRM's are the way to go!
"OSO", alkaiden seriously needs to take english 101. Because apprantly, huk'd onn foniks diddnt wurc!
