Ready-stock fat-tire e-bikes, 40 units — quick turnaround for showroom

We're a US outdoor retailer looking for a ready-stock lot of fat-tire electric bikes rather than a production order — something we can get on the showroom floor soon to gauge customer interest before committing to a bigger buy. Spec: 250W rear hub motor, 48V removable battery, hydraulic disc brakes, front and rear suspension, 20" fat tires, steel frame. We're not picky on color, just need units that are actually in stock now. Quantity: 40 units in one shipment. If they move well we'll follow up with a larger order, possibly a private-label run. We need UL 2849 documentation before we can put these on the floor — that's a hard requirement for e-bike sales in our state, not optional paperwork. Delivery: DDP to our Austin TX warehouse, ideally within a few weeks since this is a stock purchase. Please quote: unit price for 40 units from current stock, exact models/colors available now, photos of actual stock, UL 2849 documentation, and earliest ship date.
