San Francisco’s bicycle couriers.It all started in 1989 with one product: a custom messenger bag designed for San Francisco’s bicycle couriers. That unique carrier became popular with not just cyclists, but also students and professionals who loved its stylish yet durable features. Today Timbuk2 manufactures 30 products, including messenger bags, computer cases, totes, duffles, iPod sleeves, and yoga bags that generate more than $10 million in annual revenues. Loyal customers buy Timbuk2 cases at REI, EMS, Apple, and 1,200 independent specialty retail stores. The messenger bags cost from $60 to $90, depending on size; for $10 more, customers can select custom color combinations.
