Hello ... I've read of bike messengers in New York and San Francisco attaching whistles to key ring retractors fastened to their bikes. Only I can't seem to figure out a good way to attach the retractor to my bike close enough to the handlebars to make it easily accessible. The retractor has one of those long hooks that you slide down over your belt, and I guess I could attach it to my clothes, but, has anyone seen one of these attached to a bike or can you think of a way to do so?
Thanks for any help suggestions.
