I already put that I name mine but in the last week I have referred to both while riding by name.

Climbing a long hill last week on the roadie "Come on Miranda, I know we got it in us!"

Then I had a nasty wreck on the mountain bike "Alright Tess, I am not ready to give up, are you?"

I tend to think I am relatively sane but my car is named Gretchen and yes when she broke last month I begged her to fix herself.
