Weight limits for bikes is a tricky thing, as what determines how the bike will do is a mix both weight, and how you ride it. If you're just scooting carefully across a smooth surface, something like that Trek would probably hold up to 600 pounds/300 kilos.
But if you start jumbing curbs, hitting potholes and things like that, even a skinny little runt would be able to damage the bike.
But with good tires fitted and properly inflated, a bike like that should be able to deal with 250 lbs / 120 kilos during regular riding.
The documentation for the 2009 model says 300 pounds (136kg)
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.

Heh, kerb. ANSWER: Since I'm assuming you meant "curb" weight, your bike with out rider weighs approximantly 550 pounds. Max safe loaded weight is approximantly 1100 pounds. That is, the total of bike and rider and load. That doesn't mean you can safely load 1100 pounds on your bike but rather about 550 more pounds.
The weight limit is 187 lbs (pounds) or riders below 13st 5lbs (metric).
The maximum user weight that this model bike can support is 250 pounds per the manufacturer.
Only the manufacturer would be able to answer that fully.
okay there is many but mine is can carry 500lbs
A 50cc dirt bike doesn't technically have a weight limit. There are many full grown adults weighing in excess of 200 pounds which own and ride dirt bikes of this engine size.
No telling. It depends on road conditions, wind, rider positions, tires, load and rider weight ASO.
You can calculate the input force applied to bike pedals using the formula: Input force = (Rider's weight + Bike weight) x Grade resistance. This formula takes into account the combined weight of the rider and the bike, as well as the resistance due to the grade of the slope being ridden on.
Depends on the bike. Some lightweight road(race) bikes actually comes with rider restrictions. But otherwise it's just about always possible to build a bike strong enough for the majority of riders.
Not every 50cc mini bike goes the same speed, it various on, the engine, the suspension, the weight of the rider, etc.
