Propel yourself at speeds of up 12mph with the awesome Acton RocketSkates R10, which boast a range of 10 miles with a Li-ion battery that’s good for an hour and a half. Simply step in and strap on–they’ll fit most kinds of footwear, though we’d advise against heels, if you’re in to that sort of thing–and the 55W motor will move any body mass up to 250 pounds.
