In 2009, all Milwaukee County Transit System buses received front-mounted bike racks. The racks are extremely popular – more than 100,000 bikes are carried each year. Although it hardly seems possible, it’s quite common for a bus to return to its depot at the end of the day with a forgotten bike on its rack. Last year about 120 bikes were lost, an average of one every three days.
Most are reunited with owners. Strangely, some never call to retrieve their bicycles. What happens to those?
