How would you tell somebody that your motorcycle was your mistress,in spanish?

Question

I treated my motorcycle like I would a mistress,spending all my free time with it, spending alot of money on it etc. I want to tell a lady in Spain that "my motorcycle was my mistress."

Answer 1

this literally means "my bike is my lover" which is as close as I can find to what you want

mi moto era mi amante

Answer 2

Mi moto era la otra mujer and that implies that you had a wife but the motorcycle was your mistress the one that got most attention and care. I once came across a boat on my travels that was aptly named "The other woman"

Answer 3

Mi motor es mi querida.
