OP, if your suspension seat-post worked out fine, why not just get a new seat-post? Or if you need a new bike, get a hardtail and put a suspension post on it? It would be much more efficient riding for around town to have a hardtail with a squishy post than an entire squishy rear end, and especially with a cheap-o pogo stick "shock" in the rear. Also, it looks like those bikes come with big knobby tires. Not what you want for riding around town(unless you prefer riding harder, not smarter). If you planned on riding this on "real" MTB trails, I'd look at finding a better quality bike. At Least something with a decent rear derailer and shifters. Generally the generic Shimano stuff is OK for recreational riding on roads, but you'll be grinding gears and breaking/replacing stuff in no time if you try taking it on bumpy, rocky, rooty trails much. It does look like they come with a decent seat. I ran a WTB Speed V for a season on my MTB and it was totally decent. They're pretty popular, so I'd assume others agree. If you definitely want to get one of these Schwinns, at Least make sure it has double walled rims. ESPECIALLY at your weight, you'll trash single walls before you know what happened. Hell, I can't ride a single wall rim without trashing it and I weigh 150lbs.
