First of all I have spent a while reading through some threads on the forum and it really seems many of you relaly enjoy bike riding.

I am considering getting a bike so my son (age 8) and I can ride together. My issue is , like many adults, I have not braced the seat of a bike in decades. Another major concern is my size. I weigh almost 300 lbs, and while I have good strength, my endurence sucks. My doctor is tickled pink about me riding for excercise, but could offer no insight into the right ride for me. I don't know what bike is right for me. Being 5/11 and 300 lbs , buying a bike just like when buying suits, is not as simple as just grabbing the first one on the rack.

So I have the standard newb quesitons with the size factor tossed in for added complexity. What kind of bike should I be looking for for mainly street and light off road riding ( park and nature trails). What kind of money should I be ready to invest in the right bike? My son has a new bmx style bike...will this do for him for a while?

I appriciate any imput. My hope is that my wife and I will both take up bike riding and our boys will be all the better for it.
