These are the motorized electric roller skates that propel a wearer at up to 12 mph. Two sets of step-in footplates secure most types of footwear with strap bindings similar to those on snowboard boots, accommodating small and large feet. Supporting riders up to 250 lbs., each skate’s twin 6”-diam. wheels has a 55-watt motor integrated into its fiber-reinforced nylon frame. Tilting forward on the toes accelerates while tilting back on the heel gently brakes. The footplates also pivot down to put your foot in contact with the ground for walking or going upstairs.
