I just want to warn you about Knot . . . she is the great bike enabler. Sucks you in with a just come look . . . and the next thing you know your buying a bike!
LOL!!! OK... so I should or should not take Knot shopping?! I'm confused! Sounds like what I might need!

Unless you will be riding lots of dirt roads I'd stick to a 700c bike... I outfitted my hardtail MB with road tires, but really miss the efficiency of larger wheels. For the milage you're going to be doing, look for an old touring bike or road machine.
See, these are the things I need to know! THANKS everyone!
