Trolleys are divided into single wheel, twee wiel, driewiel en vierwiel. Eenwielfietse kan op smal springplanke ry, brûe, and sheep’s intestines. Hulle kan in plek stuur, wat gerieflik is om vrag te stort. Algemeen gebruikte tweewielvoertuie sluit in handgedrade bakkies (ook bekend as tierkarre) wat items dra, rakvragmotors, en bakvragmotors wat grootmaatmateriaal hanteer. One of the three-wheeled trolleys and two of the four-wheeled trolleys can be turned around the vertical axis (sien die swaaiwiele). Hierdie tipe draaiwiel kan outomaties aangepas word na die rigting met die kleinste hardloopweerstand soos die beweegrigting van die voertuig verander.
