The 3 Shops had a total of five Double Ace available, all without Batteries. That's why I have raised the Question. And one of the Bikes was partly stripped already, probably to takeout some spares.
EV Pranburi is permanently closed since a while, the one I've found is an ordinary Yamaha Dealer close to Lotus Pranburi and is not registered at Deco as official Dealer. For maintenance and repair they would bring the Bike to Hua Hin Happy EV.
