There is a name for it.
Anthropomorphism is the attribution of human traits, emotions, and intentions to non-human entities and is considered to be an innate tendency of human psychology.
My bikes have names, and I talk with them. Chas is a 35 year old custom steel frame equipped with an Ultegra group, used for training, and touring. Lou is a full carbon steed equipped with a Dura-Ace group, used for century rides. And, Thatch is a modified mountain bike used for running errands.
They are my best friends 😂
There are advantages to having 3 bikes. It reduces the wear and tear on any one bike. The drive trains do not have to be replaced as frequently. I ride more often, even in inclement weather. Thatch is equipped with fenders, and I don’t mind cycling with her in the rain. And, it adds variety to the rides. Each bike has preferred routes. Thatch goes everywhere. Lou likes smooth, fast surfaces. And, Chas likes longer rides on rougher roads.
