Is body weight equivalent to bicycle weight?
Is body weight equivalent to bicycle weight? In other words, would
riding a bicycle that's five pounds lighter be the same as losing five pounds off of your body weight? There's an old Army saying; one pound on your foot (boot weight) is equivalent to five pounds on your back. But I'm not sure what this has to do with anything. Thanks for your help. |

Is body weight equivalent to bicycle weight?
there may be some difference between
rotating weight and non-rotating. i e, wheels may matter more because they accelerate differently. other than that, it should all be 'a pound is a pound'. at least 1 lb more anywhere is a lb you have to move up a hill, and accelerate from a stop. no wait, i thought of another kind of weight - sprung [you] vs unsprung [the bike]. if you get off the saddle for bumps, the bike will 'hit harder' if it;s heavier. if you don;t get up, it;s all unsprung. wle. |

The only time when a part of the bike weight is more significant is when accelerating. Then the weight of rims and tires (and a fraction of the spoke weight) is twice the effect of weight elsewhere. All other weight in all other conditions can be considered the same (unless you wish to be very precise). I'm just refering to locomotion... if you are riding trials or technical MTB, then a light bike could be more of a factor. BTW, weight is quite important when climbing and accelerating, but not on the flat at a steady speed. There's an old Army saying; one pound on your foot (boot weight) is equivalent to five pounds on your back. But I'm not sure what this has to do with anything. I don't know if that 5 to 1 ratio is correct (surely it would vary depending on grade), but cycling is not the same as walking. When walking you have to pick up your foot to take each step, and that energy is lost, but when cycling the effect of heavy shoes/pedals cancels out (the loss of picking one up is balanced by the gain of the other pushing down). -Ron |

The old saying used to be: An ounce off the wheels equals two ounces off the frame. But it really isn't. For reasonable wheels and tires, and typical accelerations, an ounce is an ounce regardless where it is. And yes, losing 5 pounds off your body is the same as getting a 5 pound lighter bike (but a lot cheaper!). Art Harris |

Depends on where the 5 pounds comes off your body. If you lose muscle as well as fat, then you are losing strength. |

Weight on your body can mean different things -- it can be muscle that propels you or fat that you carry around and feeds you. Or even water that is necessary for life.
