New Electric Skateboard with Lithium Ion Battery for $699 with shipping

I just saw these "Mototec electric speed go skateboards" on ebay and Amazon for $699 with shipping: 

$699 for an electric skateboard with a 36v lithium ion battery and 500w motor seems like a good deal to me.

Noteworthy Specs:

• 500w brushed motor
• 36v 10ah Lithium ion battery.
• 17 miles per charge
• 20 mph
• charger included
