How about Science Fiction as part of the theme. I’ve already started on the Flux Capacitor and a Mr. Fusion.

Science tidbit: Between 70 and 90 percent of your energy is used just to push the air aside. A jump from 10 mph to 15 mph requires over 3x the energy.

Just one more reason to ride “bent”.

So cool to recognize “SCIENCE” with a special theme ride.
It permeates and influences everything we do in Bike Party.

“Meteorology” had a profound influenced our rides — like never before — from last fall through the spring.

My favorite relevant science concept to Bike Party is: “The Doppler Effect” as it relates to music trailers and lights.
Sound travels through air at 770 miles per hour.

When the source of sound is rushing towards you, the waves will not get to you any faster. However, understanding the Doppler effect, the sound waves will be compressed and the interval between them will be smaller.
This decreased wavelength, means a higher-pitched sound; and, conversely, a lower-pitched sound, when the sound source passes and moves away from the observer.
A similar effect happens with light: as the source approaches, the wavelength decreases and frequency increases, while the opposite is true as the source moves away from the observer.

My main points are: we must be prudent with our music trailers when rolling through neighborhoods at night. The “Doppler Effect” can drive standing observers in their homes to become “temporarily apoplectic”.
And bicyclist should “never ride at night without lights” because in the dark of night, there is no observed “Doppler Effect”. You are virtually invisible to an observer in a moving 3000 LB car and, you become “potential road-kill” waiting to happen.

SCIENCE: my bicycling brethren, gives the Bike Party Community a deeper understanding of cause and effect.

Such infinite possibilities with this theme!
