Are you serious? Why would someone walk around with that Nike logo on their shoes? Why would someone wear a cap with the logo of a sports team? Why would someone use a credit card branded with a companies logo? I can respect if someone prefers no branding but to have such issues with it like you doesn't make any sense to me. There's nothing wrong with branding. Personally I think the branding on those bikes add to the aesthetics.

In the end it's just a logo and some text. Don't let it get you all bent out of shape.
