My neighbor threw this bike away when he moved out, does anyone have an idea what brand this bicycle is? It has a Schwinn seat and Schwinn tires that say Schwinn Typhoon, I don't see a serial number on the bottom of the bottom bracket. I think it is one of those Walmart brands. I am pretty sure that there is sound coming from the coaster brake hub, it almost at times sounds like a bottom bracket problem but if I stop pedaling the sound from the rear is still there. It glides nicely and I rode it for 15 miles, I also noticed that the brace that secures the coaster brake is a little loose but I held my finger on it and the sounds were still there. Any suggestions, has anyone come across this before? Thanks in advance.
