Bicycle license plates have been issued since the mid-1930s. Bicycle license plates started with badges mounted to a bicycle, but after a while changed to actual plates. Around the 1950s, plate sizes were standardized and the basic format was sued from the 1950s to 2002.

I don't know much about bicycle license plates. Luckily, my old 4th grade teacher specializes in Wisconsin bicycle license plates.

Muskego

Muskego plates are confusing, yet interesting. Multiple different baseplates were in use at any given time, complicating my table. They also used just a lonely year in 1993, with just a "93" at the right.

Shorewood

Shorewood plates are notable for being super confusing. They had seemingly random changes to their replacement cycles multiple times, and not much is known on early plates, forcing me to guess that they were yearly plates. On top of that, there are "April" variations from the mid-70s onward, and not much is known on their years, either. To complicate things further, there is also normal variations mixed in with the April variation.
