I was given a Raleigh Venture comfort bike as a gift a few months ago, and took to riding very well. I am overweight, but dropping quickly. I started at 275 and sit around 250 now after two months of regular riding and a changed diet. I'm quite certain I've outgrown this bike. I struggle to maintain a good speed, usually managing just 11 or 12 mph, and the bike dealer I've been talking to says upgrading will be a tremendous difference, between better tires, lighter frame and a lower riding position.
The speed is frustrating, as this past weekend I took a 30 mile trip, which took over 2 1/2 hours. I stick to the roads, and in S. Florida they are in pretty good shape. So it would appear to me that a road bike is the way to go, but I'm still overweight, and not overly young anymore (37), so I worry maybe my back will hurt?
As a frame of reference, a dealer recommended the Trek FX series as being a little lower than a normal hybrid bike, and I'm looking specifically at the 7.3 FX. With my budget, if I went road bike, it'd half to be the 1.1 from Trek.
My main question is road versus hybrid, but I'm also certainly open to manufacturer suggestions. I am very new, and not about to customize anything, so it has to be a bike that I can buy, not a bike I buy and then change a bunch of stuff. That's not me (yet).
