I am 4'11" and 56 years old. My inseam (to the ground) is 27.5". I currently ride a diamondback hybrid. It is a very small frame but it never has been comfortable. I think that I want a more aerodynamic riding position that my hybrid gives. I am overweight and very out of shape and trying to bike to get back in shape. I've lost 20 pounds and have 25 to go. I am not a new rider, just a returning rider.

I can only ride 5 or 6 miles before serious seat and hand discomfort sets in. My current ride:


You might notice the weird seat angle. This is the only way that I am comfortable on the seat.

Anyway, I am looking for something that can ride city street, crushed gravel bike paths, and the roads, with 10 to 20 mile rides fairly regularly. The area is hilly and given that I am out of shape I need low gears more than high. Any ideas? I can pay whatever I need to pay but I don't want to waste money either.

Thanks for any help.
