He's a bit of a cunt. Laowhy86 is better,that said foreigners in China who youtube are making content for those who don't live here, so I don't find them interesting considering everything they talk about I already know and live.
I think Serpentza himself said Laowhy86 has better editing skills, too. I saw Serpentza with a folding ebike, I really need to find something similar, but I might just go with a Brompton instead.
Yeah. Bought one in 2011, and it was one with some commercial backing - could get at Best Buy, Walmart, etc., at the time. Smaller companies were probably around at least a handful of years before then.
