My question is in re the weight of bicycle tires; and whether or not the heavier tire has a beneficial flywheel effect.
I am aware that this query, as all others, will instantly evoke the braying, raucous, amused contempt of the smallminded few for which BikeForums is known. I am prepared to weather that in the hope of a reading a thoughtful, knowledgeable responce.
bicycles A and B are identical.
bicycle A has tires of a total weight of 800 grams.
bicycle B has tires fo a total weight of 1800 grams.
It is generally accepted Dr Newton was correct in thinking that an object at rest tends to remain at rest, and an object in motion tends to remain in motion. (see flywheel explanation)
A bicycle tire is a flywheel of sorts. A flywheel is in essence a mechanical battery - simply a mass rotating about an axis. Flywheels store energy mechanically in the form of kinetic energy. see explanation here http://www.upei.ca/~physics/p261/pro.../flywheel1.htm
The rider of bicycle B, with heavier tires (flywheels) must exert somewhat more energy to initally overcome inertia.
Once in motion will rider B have to exert the same, or more, energy than rider A to maintain speed?
On the downhill whizzzzz will rider B realize a benefit of the flywheel effect of the heavier tire?
Over the long haul uphill and down will rider B realize a benefit of the flywheel effect of the heavier tire?
