Olly - beat me to it! The 'gun' is his cock.

A reference to 'having balls'. Here in Aus, esp in Adelaide, you are 100% going to receive verbal abuse by people every time you are seen riding a bike. There's also a high chance that you will get hit by a car, by accident or even on purpose. The shirt is kind of a big 'fuck off' to the huge numbers of anti-cycling public we meet on a day-to-day basis.

I appreciate your initiative to make cycling wear but.....

I don't know where, or how, you are cycling in Adelaide to give that impression. I lived there for more than a year and I cycled everywhere on all types of bikes (2006-2007 and I've regularly visited since then). I had absolutely NO trouble whatsoever. Adelaide is a fantastic place to cycle with its extraordinary wide streets, amazing weather and very little traffic. (Sydney is a different story!) I certainly did not need 'balls' to ride there and, in my opinion, a shirt that yells out an association between bike + 'cock' is pretty unappealing.
