Yep, I am 100% deaf while I am riding either my bicycles or motorcycles. I am about 80% hearing when I wear my CI's. Welcome!!
I wear a small mirror that hangs from my helmet when I ride on main roads. I don't bother with the mirror when I am in state parks, trails, etc.
FYI, some cyclists on board here think deaf people are nuts for commuting...see this thread:

Yeah, I've been run off the bike lanes by irate drivers, and many left-turners don't wait for me. I avoid sidewalks unless I absolutely have to use them.
