Could you imagine trying to keep this bulky, square box safely fastened on the handlebars of your bike? It’s a 1950s Arvin 514Y23-13 AM bicycle radio/horn with a reflector that I acquired in 2013 for inclusion in my transistor radio collection…and it still works! While the reception isn’t the best ever (would be hard to hear near street traffic), the radio does work, as does the horn.
While quite un-aerodynamic, it’s “cool factor” comes from the fact that it represents the pre-FM era and reflects the then-current technological advances of the post-World War II era. I must say, of all my transistor radios, it is certainly one of the most unique and intriguing. Cheers!
