Re: Unspoken rules?
I personally enjoy the out of the box thinkers. Also thought with out peddles it is no longer a bicycle until I saw one that was amazing! In the state where I live (CT) A "bicycle with motor assistance" needs not have peddles to be legal.
So, no, I do not think there is an unspoken rule other then play nice, don't curse unless it is funny and the whole running with scissors thing.
"Build it, and they will look at the pics"
If one is kind to their fellows, they have every right to speak. Same as the next poster. IMHO.
Post Script, great to meet ya!
