I weigh 340 lbs and I'm looking to get a new bicycle. My problem is that all the bikes marketed towards obese riders are way out of my budget. I don't want to spend more than $600 on a bike.

For now, I just plan on riding on the road and paved bike paths for exercise but when I get under 275 lbs I want to start doing some light trail riding. What bikes do you think will suit me? Will I be fine with a normal bike as long as I don't drop off curbs and stuff like that?

Sorry if this question doesn't belong here. I couldn't decide whether this question belonged here or in /fit/.

Pic related is the bike I'm considering. The Giant Roam 4 Disc. Their website says their bikes have a weight limit of 300 lbs. Thoughts?
