Human & Animal Connection

-Came across these 4 illustrations of a comparison between the human skeleton and that of a few different animals which we may interact with.
-Although quite different in general appearance, when it is broken down like this to the skeletal structure there is not a lot in it besides our scale.  

This is perhaps the reason we have such strong connections with animals i.e. our pets, a deep care for another is built.

I would like to try and transfer this connection into my bike designs.. perhaps literally? or use this as a source of personification. Changing the view on machines, more friendly manner.. adding a personality and making the bike not an object, but more a friend or pet
