The Trikke T67 Three-Wheeled Carving Scooter lets the rider "surf the street" and exercises the whole body as a side-to-side motion propels it forward. This model is adjustable for anyone 4'6" to 5'4" and up to 200 lbs. "There is a trick to making them go, which must be learned, but children seem to have an easier time than adults. Though it is not necessary, Trikke can provide an instructional DVD to loop in the store," a company representative told TDmonthly. Launch date: January 1, 2003.
