Hello everyone. I've recently become interested in getting into cycling. Currently I own a mountain bike, its probably over 10 years old. There are so many different brands and styles I don't even know where to start. i'll probably be mostly riding easier trails and around town. I had undergone knee surgery this past January and can no longer run with out pain, the impact in the joint isn't very fun. However riding a bike doesn't bother me. I'm hoping that someone here can point me in the right direction for a decent new starter bike, maybe something around $400-450? I also wouldn't mind any tips on accessories I should buy and things to take with me while out riding.
