Who has fat-tire e-bikes in stock? Need 1,200 units, DDP Raleigh

Who has fat-tire electric bikes in stock right now that you could ship without a production run? We're restocking a line we already sell, not testing something new, so we already know it performs — we just need supply fast. Spec: 250W motor, 48V removable battery, hydraulic disc brakes, front and rear suspension, 20" fat tires. Any current color or finish works, we're flexible there. Quantity: 1,200 units in one shipment. UL 2849 documentation needs to be on file and current, not a certificate from an older model revision. Delivery: DDP to our Raleigh NC warehouse. Please quote: unit price for 1,200 units from current stock, what's actually available to ship now versus what needs a production run, current UL 2849 documentation, and the earliest realistic ship date.
