Hoverboard seat Attachment, Hoverboard go Kart for Adults & Kids, Accessories to Transform Hoverboard into go cart, Hover carts for self Balancing Scooter, Pink (Hoverboard not included)

Some assembly required. The "tools" provided are minimal at best, adding to the tricky assembly. I switched to real tools and things went far faster. The large threads were tricky to work thru also. After the larger body parts were put together and tightened things were easier. These karts are sturdy ... for children. The hoverboards (sold separately) are attached via two Velcro strips (one on the right, one on the left) which seem to wear out very quickly. After each use you really need to recharge the hoverboard batteries and check to make sure all screws and bolts are tight. I bought 2 for my grandsons and we use them while camping. The kids are 5 and 7 and it took some time before they felt comfortable controlling the hover karts safely. I added tall bike safety flags to each kart so cars could see them on the campground roads. Always ... Safety FIRST!
