I may generally lack a sense of balance but that doesn't stop me from wanting a pair of these remote-controlled electric heel-skates. Oh wait, 80kg weight limit? And this is coming to America?
SpnKiX are mechanised roller skates. They run for up to three miles, at speeds up to 16 kilometres an hour, on a single two-hour charge to their LI-Ion battery pack. Users control their acceleration through a hand-held remote, presumably braking as well. They're available in Men's 6-14 and Women's 7-15.5 but can only support 80 kilos, which seems really light given that they're sold in Men's 14. The SpnKiX are currently still a prototype Kickstarter project with only $US2,845 of a $US25,000 goal fulfilled with 44 days to go. [SpnKix via Kickstarter]
