I'm not really a BMXer but I just like to ride all types of bikes. I picked this up at the local thrift store last year for $4.50, it's a Schwinn Mag Scrambler. I was hyped to find it as I was trying to find a bike like it to mess around on. I put a mongoose seat and a cheap pair of tires from eBay on it. A few months later the same thrift store had these mongoose pegs for sale so I put them on the back. I ride it around the neighborhood when I'm bored. Total cost put in this thing is about $25-30. I should probably get around to getting the rust off the chainwheel.
edit: I like how when trying to remember how much I spent on it I forgot the question. Does anyone know how old these generally are?
