View of Lake Union from the Lake Washington Bicycle Path, Seattle, circa 1902 (MOHAI 9971)

Between about 1894-1904, after the horse and before the automobile, bicycles were the hottest new form of do-it-yourself urban transportation in Seattle. The region's many cycling groups regularly sponsored outings along the twenty-five miles of urban bicycle trails which were built, funded, and maintained with the aid of city engineers. Bike cops enforced cyclist speed limits, safety, and dealt with the scourge of bike thefts. There were over 20 bike shops on Second Avenue alone, and it's estimated that there were 10,000 cyclists in a Seattle of about 100,000 citizens.
This image of Lake Union was taken sometime between 1900 and 1903, facing north from the 10-mile-long Lake Washington bicycle path, built in April 1897 by the Queen City Cycle Club (later Queen City Good Roads Club). The Lake Washington bicycle path began at Eighth Avenue and Pine Street and continued out through the woods to Lake Washington by way of Lakeview and Interlaken Boulevards. The Halfway House served sandwiches and drinks.
