Well, I've seen some numbers that a single wheel will collapse at about 300 kg of static load. On a bike there are obviously two wheels to share that burden, so it should be able to take more. However, this was for a static load. During actual riding the bike will see load transients caused by bumps in the road, so the function max allowable load is probably a bit lower. No note that just because it is possible to build bikes this strong this doesn't mean that all bikes are built this strong. Particularly in the road bike crowd there's a huge interest in keeping bike weight down as much as possible, and there you can frequently find both components and bikes that are only rated for a certain rider weight , usually somewhere above 100 kg.
Sort of. High-end road bikes might come with weight limitations, but the rest is more down to riding style and expectations. One (standard) bike wheel can take about 600 pounds static load before collapsing. The dynamic loads of riding are of course different, but with a bit of attention to riding style and choice of bike almost everyone can ride a bike.
Very much depends with how you ride, and what you think of as an average bicycle. Road bikes tends to get into troubles with riders over 220 lbs, unless special care is given to the design and build of the wheels. But if you're a careful rider who stays on even surfaces you can get a bit more out of them.
Only the manufacturer would be able to answer that fully.
It depends if you want a street bike or an offroad bike. There is no age limit for riding offroad, but to ride on the street, you must be at least sixteen.

there are no age limits for dirt bike. but there are recomendations for size
Of course! Bike-riding is a fairly intense form of exercise that will help keep you fit and lose weight.
I just read on Schwinn.com that there are no weight limits for Schwinn bicycles because it's more the way the bike is used rather than the weight of the individual on the bike. Their example is 120 lb boy riding bikes over curbs, bouncing on the tires, etc. will do more damage to a bike than a 400 lb individual riding the bike for exercise purposes. More information on FAQ's can be found at the website.
The weight limit is 187 lbs (pounds) or riders below 13st 5lbs (metric).
Riding a stationary bike is a great way to lose weight. Any kind of physical activity is a great step toward healthy living and personal fitness.
Doing various types of squats, walking, and riding a bike
The maximum user weight that this model bike can support is 250 pounds per the manufacturer.
Certain bike has weight limit when it was designed. Mountain bikes with air suspensions need to be adjusted for the weight of the rider by putting in or taking out air from the suspensions.
