bike calculator

Inspired by a few young engineers and their obsession with reading the output from their spin bikes at lunch.

Bikers love performance calculators.  Here's one I like.

How I understand it.  If you can put out your weight in watts, you are doing good.  Say a 150 lb person producing 150 watts continuous.

If you can sustain 1.5x your weight in watts, you are doing very good.  Say your 150 lb person producing 225 watts.  2x your weight in watts, and your are an age group placing runner or cyclist.

If you are Lance Armstrong or Greg Lemond biking up a mountain, you are putting out maybe 500 watts continuous.  Enough to light up a few dim bulbs.
