But to the O/P: I'm somewhere between 300 and 350 (haven't weighed in about five months); at my heaviest I was 360.

I'm just riding around on a steel Ragley mountain frame with decent parts hung from it including a Mavic downhill wheel out back - actually cracked the original wheel in half, so went with a stronger piece just to hold my fat ass. Breakage might happen but it isn't the end of the world. Consider a break a chance to upgrade! Find yourself a halfway decent USED steel mountain frames and stick to paved roads and gravel type rail trails for a while. Once you lighten up, you can try some pump tracks and mountain stuff (I've done it even over 300#).

I just did 50 miles today on this disasterpiece:


That's my third half-century of the year and all have been closer to 350#.
Don't wait to get under 300.
Get a bike, and get on it. What's the worst that could happen? You break it? Big deal. Fix it with stronger parts and keep on riding.
Start at 1 mile and increase gradually.
Walking sucks.
