$400 · 2x go-kart hoverboards $400obo

We have two hoverboards with go-kart attachments for sale. Xmas gifts 2 years ago but our spoiled kids rarely use them anymore. Hoverboards are 10" wheels with 15kmh top speed. They rip around great on pavement or offroad/grass. Suitable for 5 and up. The go-kart attachments go on and off easily but we leave them on because its way more fun. Steer with the handles like a skid steer. Hoverboards have Bluetooth speakers and lights for visibility. Great battery life, we've literally never died, and stays charged with weeks between use. We dropped $1000 on these ($800 boards and $200 attachments) and sick of seeing them collecting dust. Similar product in video link..
