I stumbled across this little GT Mach One BMX bike in a thrift, and bought it on a lark. It is made from 4130 chromoly, and seems to be a quality built bike. The trouble is, I know nothing about BMX bikes. It looked cool though, and for $5.00 I took a chance.
How'd I do? Any idea how old or good it s? Might it be worth something, or was in a thrift shop for a reason?
