Mr. Prosser is a bicyclist. In October he sent Jim Sherman a letter inspired by the recent BPD brochure on bicycles. He notes that BMC 15.56.020, which prohibits bicycles with a wheel radius of over 14" from riding on the sidewalk, in effect allows all bicycles to be ridden on the sidewalk. He suggests that the code be amended to read "diameter." He also suggests that, in the future, the brochure correctly use "wheelbase." Please refer to B&PSC and the Traffic Commission. Thank You.
