16" scooter board with handles and 4" "Fast Trak" non-marring PVC wheels. Double race bearings make this the smoothest, fastest, most durable wheel available. Larger wheel diameter means it sits higher off the floor and this makes it easier for older kids, adults and adapted PE. Great for alternative surfaces — even carpet. The wheels sit “outside” the edge of the board for extra stability and have a protective shield over them. Sold in sets of 6, 1 each red, blue, green, yellow, orange and purple. Made in USA and hold up to 250 lbs.
