bike for obese people

 Do they make a bike for big people?  I am just starting to exercise and think I would enjoy riding bike with my kids for exercise.  If anyone has a suggestion on a certain brand or type I would appreciate it.

Most bikes are rated to hold a certain amount of weight and it's higher than you'd think. There is also a company that makes bikes for the SMO.
