I am 38 years old and used to be very athletic and can still move around really well for a big guy. My 2 kids are riding bikes and I want to be able to 1. ride with them and 2. be alive in 10+ years. I have already started to limit myself to 2000 calories or less a day and now need the exercise part, I get too bored of walking.

I see all these posts but nothing concrete of where to go to buy all these things and what specific to buy.

I prefer not to spend 2500 but the zeze bike is there and I saw that the surly Wednesday bike holds 355 lbs which I believe as long as I don't go crazy should hold which is $1500. I would like to spend less than 1k but not sure if that is possible.

I wanted to know other options that area readily available or specific things I should ask for parts,frames etc.

Thanks in advance.
