spnKiX Motorized Skates are a fun and smart way to help save the environment by reducing dependency on cars to commute short distances. Using the spnKiX as an alternative to driving short distances can have a large impact on the environment by reducing CO2 emissions and cutting down on gas used which ultimately saves you money. The spnKiX Skates quickly and securely attach over your shoes with dual fasteners (similarly to bindings on a snowboard) and are powered by a integrated lithium-ion rechargeable battery that has a range of up to 6 miles per charge. Each spnKiX skate has its own independent motor and battery pack with a handheld wireless remote to control the speed for both feet. They have a max traveling speed of 10 mph and a max weight capacity of 200 lbs. spnKiX estimates that using their motorized skates in lieu of driving a car for short commutes just once a week can save you up to $300 in gas a year.
