If you want a little of both, then a comfort bike is probably more what you are after..more than a hybrid anyway. The main difference, as far as I can see is that the hybrids have smooth (road) tires and most comforts have tires that accomodate both paved and offroad.

I have the Trek Navigator (300 model) and its tires are smooth in the middle and nobby on the sides. This makes it (tire wise) ok for either pavement or offroad (but not ideal for either). Mine also has suspension in the fork and seat which is also good for offroading I believe.

Hybrids are about the same but with smooth tires all the way, which makes them pretty much only pavement bikes. To me the name is misleading.....when I first got into this hybrid "spoke" to me as being a hybrid between road and off-road, but that is not the case. I think its more of a mountain bike frame/syle with road tires.

The Nav 300 and 100 have the same frame....only real difference is components I believe. Not sure if the 100 or 200 have the suspension or not, but you probably want it if you want to offroad a little.

BTW....I've since put road tires on my Trek Navigator 300 as I only ended up riding pavement....and it is much smoother. I do love the bike.
