Zip--I'm not certain why all the dealers are out of stock, $140 is a great deal, I haven't seen any that cheap. Gasbike and kingsmotorbikes both want $200 for the GT2-S and both are out of stock. The GT2-A with the pedestal mount is $140 at kings HERE
and they sell one for $160 that comes with Disc Break Caliper Brackets for the extra $20 HERE
and both are in stock. It just seems that the GT2-S without the pedestal mount is out of stock. However the Alibaba link that I posted says that the minimum order is 10 and they can produce as much as 2000 a month so maybe the dealers just had a run on them or something, Possibly they are lagging on ordering them because they are expensive and require a large outlay of money to get 30 of them or more, I don't know.
