I don't normally think of myself as heavy, but there are some really small people out on the bike paths.
Not everyone is meant to be a greyhound.

I take pleasure in knowing that I'm working on my bone density.

TE'ers are very supportive here and they will be happy to answer your questions regarding bike choices. My first road bike was a Terry. Then I graduated to a Specialized Sequoia. I like having relaxed geometry because it's very comfortable and the more comfortable I am, the more likely I will ride it.
