Each set is themed, so wheels may not apply to all sets, there are a couple on this list that are designed to inspire cars and other motorized vehicles. Each set does come with extra pieces and props to match the intended theme of the toy. Some of them have characters or little toy people to play with the finished structure when it is assembled, and some of them are made to hold and transport the bloks they come with along with other blok sets. Make sure to look at each product to see the included pieces and parts it has to prevent any duplication of bloks or accessories.
