okay, so recently, i have started riding my dads bike when i get bored, and i decided it was something i really liked doing. his bike is a schwinn racing bike, and considering its a mens bike, its a bit big and uncomfortable for me. so i got my own bike yesterday. its not a racer, its just a casual riding bike. i think its called a cruiser. anyways, i want to get into stuff like going on long rides and group rides and stuff. i plan on getting an all terrain bike or a mountain bike or something like that soon so i have a little variety in riding styles, but since im new to this whole thing, i need advice on basically everything, what type of bike to get, how to build up endurence so i can ride so many miles in one day, how to maintain my bike, basically any information pertaining to biking will be helpful here. thanks.
