The MVC issued an advisory about the new autocycle vehicle class in January 2017 - it predicted new plates for autocycles by mid-2017.

The first AUTOCYCLE plate sighting was October 28, 2017.
The numbering format is A1A1A, and if the progression is similar to moped plates (the other 0A0A0 type) then it would start at A1A1A, go to A1A2A, etc up to A9A9A, then A1A1B and so on.
(I would guess that zeroes are not used on this type.)
