So I just started cycling and love it. I'm using an old bike though and really need an upgrade. I have only been going about 10 miles a day but hope to increase that and would like to ride in a few 50-80 tours next summer. I know that's a big goal! I'm looking for rec commendations on bikes though. I don't even know what type I need! I don't like the road bikes because of the handle bars but Im not quite sure if I need a mountain bike if I'm mostly on the towpath and occasionally hilly roads. I'm 5' 6". Any info on styles, brands, etc would be helpful! I don't want something cheap again, but I don't want to necessarily pay 1000 dollars either. Thanks!
