Connect Chalktrail to a bicycle (child or adult size), then get riding! As you cycle, the chalk draws your route. Draw figure-of-eights, wavy meandering paths, perfect circles, or fascinating designs by retracing the same route again & again in succession. Create a masterpiece with a group of riders. Playing follow the leader becomes thoroughly creative! This is a wonderful way of improving bike-riding skills & confidence. One piece of chalk lasts 1.5 miles. Additional coloured chalks are available as well. Assembly is extremely simple (no tools requires).
