Ethical question

I am, yes.

It's only a bike, this in not Darfur, let him dress his bike up as he likes, I agree it would be dodgy (I save the term 'immoral/unethical' for more lofty concerns) if he were to attempt to pass it off as something it was not when selling - but he has not said he is doing this.

Of course you can ! Just don't get caught ! :P Your avatar nicked from the BBC weather website is not going to be of interest to the BBC lawyers any more than some bike fan sticking some logos on his bike or someone nicking McDonald's logo for a piss take T-Shirt.

I don't see any of this as a big thing, certainly not an ethical question.

Yes comparing pretty much anything to Darfur is a great way to take the oomph out of the debate, but it's also pointless. So let's move on. "Immoral" and "Unethical" are terms that are used for all levels of discussion, using it to discuss ripping off someone's life work is pretty spot on.

My avatar is not BBC's logo. Also I am in no way alluding to each of my posts being a weather forecast.

This dude is wanting to use a craftsman's name on something that he didn't craft. Would he be happy? Nope.

I'd also say that stealing a large company's logo is very different from exploiting a small independent company. A large company won't feel it, the smaller one can be really hurt by it.

This is definitely, without a doubt, defined as an "ethical question" being that it is a question of one's ethics.

Yoss, you asked because you know that this is a questionable thing to do. Regardless of the ethics, wouldn't you feel kinda dumb doing this? I'd be hella embarrassed!!
It's like telling a girl your a doctor when your hitting on her and then having to back that up on your fifth date, having to buy a beeper and a stethoscope, and eventually the girl's going to figure it out and think you are a complete loser/wack job.

If you don't like the bike you got, sell it, buy a new bike. Or use the bike you got to make it yours, not a fake of someone else's.

Don't be a fake!!!!

....but yes, as Tynan so brilliantly put it, of course you can [do this], but like Jeff Goldblum said in Jurassic Park, Just because you can, doesn't mean you should.
