Sample order first: 6 units of the carbon-frame hidden-battery fat-tire e-bike

We want to test this model before deciding whether to list it permanently. Carbon fibre frame, hidden battery, front suspension, 7-speed, rear hub motor 36V/250W, 10.5Ah battery, disc brakes — looks like a strong fit for our lineup if the build quality holds up in person. For now: 6 complete units, standard colours, no custom branding needed yet. We do need CE certification documents we can post on our product page, and the UN38.3 battery paperwork for customs clearance. Delivery DDP to our fulfillment center in the Columbus, OH area. If the sample units check out, we'd likely follow up with a real order in the low hundreds. For now, please quote 6 units, tell us what's already in stock versus what needs a production run, and share a couple of close-up photos of the battery mounting and frame welds if you have them.
