I bought my Typhoon frame in the end of May, just compeleted the bike a couple of weeks ago. I haven't motorized it, but I have been riding it around as a bicycle and it works very well.
There was originally a problem with the frame, the swingarm was not symmetrical, it had a 2mm height diffenence, so the wheel would not sit straigt in the dropout. I only noticed it after I had installed the rear brake and I noticed a rubbing sound when turning the wheel, so I looked at the caliper and I immediately saw what problem was. I first had some trouble convincing the Vector support that there actually was a problem, they first said that the caliper does'nt have to be straight relative to the swingarm or something like that. After a while I got the point across and they agreed that the swingarm was not properly made.
They sent a new swingarm and covered the shipping for the old one, so in the end I got what I paid for without any additional costs, and I'm very thankful for that, because I know from experience that not all ebike sellers would provide this kind of service.
One thing I want to mention is that if you buy the moto seat, it can't be bolted on directly with the included nuts, you need to buy spacers. (I think neccesary mounting hardware should be included) I bought these aluminum clearence spacers on Ebay, and they fit perfectly. (I chose 12mm length)
