'When you increase the mass the speed increases by cubic function, whereas if you increase the aerodynamic drag the speed decreases by a square function. Hence why cyclists who are heavier can go faster,' Fonda says.
If you're carrying a lot more body fat you're less aerodynamic as well. That's an additive effect: not only is your power-to-weight ratio lower, but you've also got more drag, so that's going to make you slower as well.
Because the force of drag is independent of mass, it will be roughly the same for both individuals. However, the force of gravity parallel to the incline will be increased for the more massive individual and therefore so will the acceleration.
You'll also average 12.22mph, versus the 11.46mph you would have averaged at 180 pounds. Going up a two mile-long, 10-percent grade will never feel easy, but it will be a lot easier with your lighter frame. What would have taken you well over 26 minutes at 180 pounds will take you just over 24 minutes.
Believe it or not, when objects roll downhill, it's not their weight or size that determines their speed—it's how their weight is distributed.

Key Points. Heavier people not only have more fat mass but also more fat-free mass, likely making them stronger (in absolute sense) compared to normal-weight people. Heavier people are more positive about strength exercises compared to (1) normal-weight people and (2) aerobic exercises.
Cycling is great for heavy people because it puts less impact stress on our joints and bones. Even more important, it is the perfect exercise because it is fun.
Road bikes will weigh between 6.72kg and 9.57kg on average. They weigh the least as they are built for speed. The lightest road versions will have a carbon-fibre frame and forks, as well as the lightest components. Lighter bicycles will compromise ride quality and offer fewer options to add accessories.
The average weight of a mountain bike
On average, mountain bikes weigh between 9.5kg to 13.1kg.
Weight affects speed down the ramp (the pull of gravity), but it's the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
The only thing that has changes is the mass, and since mass is not a factor in determining top speed, so top speed should stay the same.
He explains that heavier riders won't go much faster than the speed of the water itself. "They can't break through the deep water," he says. "But a lighter rider—that person will get flushed and get swept up by the water and they'll eventually reach the speed of the water."
Bicycles do have weight limits. But with so many different types, geometry, materials and parts used, it's impossible to standardise. Generally however, most bikes will have a weight limit of between 275 lbs and 300 lbs.
Rule of thumb equation for appropriate weight is to take 100 pounds for the first 5 feet of height (for women) and 106 pounds (for men). Then, add 4-6 pounds per inch of height above this base (women), and 5-7 pounds per inch (men). Now, this can be used as a baseline calculation, but there is a lot of variability.
Bottom line: A lighter bike may save you a few seconds per climb. But if you really want to get faster, there are better ways to spend your energy and money, like shedding bodyweight, upgrading your wheels, and making your bike more aerodynamic.
The weight of an average bike is around 20 kg. This is an excellent weight for normal use.
You have to remember the fact that it is a heavy bike and not a bicycle that can just be lifted like that. Moreover, if you are not a gym freak or a muscle champion but a regular guy or girl, it is even more difficult to rely just on your muscle power.
If you're looking to get fitter, trimmer and lighter – not to mention healthier – then cycling is a great way to lose weight. It's efficient, enjoyable, easy to slot into a busy day and, best of all, has emotional and mental benefits as well as physical ones.
Additional weight increases inertia and wheel inertia matters a lot in cycling because the rider has to overcome it to accelerate. Heavier wheels require more energy to overcome this inertia. Many riders, even novices, can feel the difference when riding lighter wheels.
According to a new study, overweight men are less prone to premature ejaculation and, thanks to a higher level of estradiol (a female hormone that delays climax), big dudes also tend to last longer in the sack--7.3. minutes, to be exact.
Part of the reason for skinny, but strong is the number of reps. Too many—12 or more, improves endurance, not bulk. Too few, three reps or fewer, gives you power and strength but not muscle growth. Not working to metabolic fatigue will keep you strong but skinny, too.
Your muscle mass makes up most of your weight
Because muscles are more dense and heavier than fat, bodybuilders and other professional athletes like football players are often considered obese or overweight based on their BMI alone.
