The key here is that the higher the mass and speed the more energy is carried. This means that variations in power, friction and wind pressure are 'smoothed' by this 'possessed' energy which keeps speed more constant. Obviously the resurch determined that the most efficient package to achieve best results required the bike to be a certain weight and not the lightest bike which would carry the rider.
Of course the heavier bike probably also provided the stiffness required to make best use of the power of the rider.
hahah, you teach me about KE, ROFL. LOOK AT MY NAME.
Kinetic energy isnt exactly 0.5mv^2. Thats only an approximate, in non relativistic speeds. Dont give me physics lessions plz newb.
I could counter many of your arguements by a lot of things. Since kinetic energy is mass to the FIRST power, and velocity to the Second power. An increase in velocity is going to give you a bigger jump in KE. A lighter bike is faster, and will result in high KE, because of its velocity aspect. A 15 pound bike going 30 mph has twice the Kinetic energy as a 30 pound bike, going 15 mph.
Variations in friction, wind, is pretty uniform in tracks.
also, i got another question, how does velocity stability increase bike speed?
ROFL, plz answer.
If weight didnt matter AT ALL on flats. Then why not make a 200 pound bike, and put some bling bling on it? Make it prettier or something.
