There have been several threads on this and I think a slight majority of us name our bikes. I name all of mine:

Miranda- the feisty roadie
Tess- My hardtail mountain bike, she is a Scott Contessa but she is so tiny just Tess.
Fiona- since sold but she was my first road bike.

Holly Golightly - my new love is my full suspension mountain bike.

And yes I talk to my bikes when I need a little extra push. "Come on Holly, we can do this" or "you're right, Miranda, I am a wimp. Let's go!"

I name my cars too and DH's last two trucks but I don't talk to them.
