1940 Motorola Bike Radio

1940NovPS4Eighty years ago, this cyclist was able to enjoy her favorite program no matter where she happened to be pedaling, thanks to this three tube set shown in the November 1940 issue of Popular Science.  The set had a loudspeaker that faced the rider, and included an antenna that attached to the tip of the front fender and curved back. A separate battery box, supplying 90 volts B+ and 1.5 volts for the filaments, clamped securely to the bicycle frame.

While not identified by the magazine, the set appears to be a Motorola model B-150, featuring a tube lineup of 1A7GT,3A8GT, and 1Q5GT. If the set looks familiar, it’s probably because we previously featured it in connection with an ad allowing boys to win a free example by selling subscriptions to Radio Guide magazine.

Since this cyclist clearly isn’t a boy, she presumably paid the retail price of $19.95.
