Unicycle Term Pronunciation

I am a unicyclist but I have never talked to one in person. I read and use many common uni terms but recently realized that I don’t really know if I am pronouncing them correctly.

Some of the words I am wondering about are:

Uni
MUni <---- Mostly this one.
Coker

I’m pretty sure about most of these but I just wanted to make sure.

Any others you want to add would be great.
