The Katy is what was once rail bed, so for all practical purpose it is flat. Hermann on the other hand has some hills, but is very doable on bike. Hermannoff and Stone Hill can both be reached in absence of hills that would prevent the novice from visiting. There are also several B&B's that can be reached by bike. To my knowledge there are no bike trails, but the Hermann streets are quiet and easy to ride with little traffic.
