I'm a newbie and had a question about what type of bike to get? I'm looking to train myself until i am able to make a 70 mile ride from the Bay Area (East Bay) to San Jose. So if anyone can please tell me what type of bike would be best suited for my mission, i would be thankful. I'm only expecting to be on flat surface and going through some small hills, so i believe i am looking for comfort as my 1st priority. Pictures of the style of the bike would be nice too. =) thank you.
