Nice bike. A few questions about it. What is the white thing that is covering the front brake and protruding out? Is it a whistle of some sort, like one of those deer or dog whistles? What is on the back of the seat? Is it some sort of cage for a bag or something? Lastly, it looks like you can only brake when you are in the down position with your hands on the lower part of the ram handles. Is that the case? I have an old 10 speed from the 70's and it has those ram handlebars, but it has dual brake levers so you can brake from either position. Does riding in such a position hurt your back (the old 10 speed I have is unusable at the moment, I plan on fixing it in the summer, needs tires and new cables). I ride in a fairly upright position leaning forward at about a 45D angle and I find it takes all of the pressure off my back. I can't walk 2 blocks without pain, but I can ride for hours (without back pain).
