Plot synopsis:
A little dark-haired girl named Jenny dresses as a boy and plays with her friends (all boys). One day, her best friend Buddy shows up on a bike equipped to handle phone calls. Later that day Jenny spies a suspicious man leaving the home of an elderly man. She comes in to find the owner knocked out cold on the floor. She immediately telephones her friends on the bike, who follow the burglar and his car. They manage to capture him and a heavy-set woman (his wife?) helps the boys bring the bad burglar and the stolen money back into town.

I've also uploaded a scan of a Johhny Jones exhibitor ad from the 9/23/1922 Moving Picture World with Gertrude Messenger and Edward Piel Jr. pictured.

This is one of the "Johnny Jones" series of two-reel comedies made in 1922 into early 1923. The series starred Edward Piel Jr., who was known as Johnny Jones, and Gertrude (Gertie) Messenger. In the scans Jenny is Gertie Messenger, and her friend Bubby is Edward Piel Jr. The film is BROADCASTING, and here's a review from the 10/29/1922 issue of Film Daily (pg. 20). It gets to the business about the radio-bike and burglary at the very end:

"BROADCASTING" - Johnny Jones - Pathe
Type of production --- 2 reel comedy
Here is another of the Johnny Jones-Gertrude Messenger offerings, and those who saw "Makin' Movies" will be anxious to see this one. It is thoroughly enjoyable and will please any audience. Johnny Jones and his youthful supporting cast will enlist everyone's sympathies and little Gertrude Messenger is charming in whatever she does.

The radio craze has hit the town and an outfit is offered as a prize to the child bringing the largest number of new members to the Sunday school. Many and varied are the lures used by the kids to get members, but Gertrude and Johnny win out by advertising at a picnic at which members are invited free. They win the prize and with a radio-equipped motorcycle they solve the mystery of a bank robbery and attempted murder and bring the crook to justice.
