So I'm very anxious to build my first bike but I want to make sure I have a quality set up before I begin. I've been liking the Schwinn cruisers, in particular the SS-X Blackout and the Point Beach. I saw a SS-X at a bike shop and the frame looked skinnier than other models. Will this pose a problem? Also, the SS-X has a coaster brake, what are some pros and cons to other brake types? Lastly, I would appreciate any advice or comments from others who have gone with a Schwinn. Just looking for good info to help me start with a quality motored bike and no junk parts that will need replacing.
