That seller is me.
The reason I asked for remittance in full or cash up front if you prefer is that the buyer, underpressure, responded with no questions asked about my bike or the accessories offered which I found kinda strange.
The other thing is when I searched for underpressure's profile I saw that they joined in 2024, had no posts and a seemingly made up name consisting of random letters (see below screen shot).
I consulted Larry Oz about my potential liability with this sale and he recommended the course I took - accept either Zelle of a personal check, waiting for the check to clear of course.
In my defense I will state that I am a long time member of the forums, a Cruzbike enthusiast for over 15 years I have sold and purchased bikes and accessories on the forums, attended a rally and am personally familiar with a number of Cruzbike notables including Robert, Maria, Larry and ratz who, I believe, would vouch for my integrity.
