In late 1998 my brother and I bought out the remaining inventory of the Interchangeable Bike Jersey the forerunner of our current BikeMania 3 in 1 jersey. We sold them from the trunks of our cars at bike events and on auction sites. A year later we had rudimentary web site offering 10 items for sale.In late 1998 my brother and I bought out the remaining inventory of the Interchangeable Bike Jersey the forerunner of our current BikeMania 3 in 1 jersey.
