A summertime of sidewalk fun! Your Sidewalk Seurats and Concrete Cassats can leave lovely lines as they ride their two-wheelers with this clever, award-winning Chalktrail for Bikes from Fat Brain Toys attached to their back wheel. The Chalktrail clamp attaches quickly and easily without tools and rides along behind, trailing bright chalk to make swirls, swoops, or straight lines as kids pedal their way to fitness. Once riders get the hang of it, they will be composing miles of colorful chalk creations that will make passersby wonder how in the world they got there. The included piece of non-toxic, washable chalk can leave a trail for up to 1.5 miles and the Chalktrail holder will fit most bike wheels from 12 to 29 inches in diameter. Available in blue or red. Chalk refills available separately. Ages 3 & up.
