This set of four mini pulleys allows you to experiment with motorized cars and equipment of your own design.
The small 10mm diameter pulley has a 2mm-diameter hole that push-fits the shafts on our small motors. The three other pulleys are 20mm, 30mm, and 40mm in diameter. These three larger pulleys have center holes 3mm (1/8") in diameter to fit a wooden or metal axle/shaft. The pulleys are about 6mm wide and made of durable black plastic.
