This seat attachment turns a self-balancing hoverboard into a seated ride, fitting most 6.5, 8, 8.5, and 10 inch hoverboards as long as the foot pedals measure at least 16.93 inches wide. It straps onto the hoverboard footplates with sturdy built-in straps, so there is no complicated installation and no tools needed. Built from heavy-duty, well-welded metal, the frame supports up to 220 lbs, sturdy enough for an adult rider while still easy for kids to handle. The frame length is adjustable to fit different ages and heights, and the whole unit measures 36.4 x 24 x 12.7 inches at its longest, 32.3 x 24 x 12.7 inches at its shortest, and weighs just 8.37 lbs, so it is quick to attach and remove. Two 360-degree rotating front wheels paired with grippy foot pedals let riders steer forward, backward, left, and right across sidewalks, driveways, and grass, while the ergonomic seat, backrest, and anti-slip footrests keep the ride stable and comfortable for the whole family.
