The motion of the connecting wheels is an interesting phenomenon in physics because it is found in everyday life. This connecting wheel motion experiment should be carried out in physics learning. However, this experiment was rarely carried out due to the unavailability of equipment and the covid-19 pandemic. The solution to the problem is to design a connecting wheel motion experiment system with remote laboratory based on website. Remote laboratory is software to support experimental activities through long distance. The objective of this research was to investigate the accuracy and reliability of stepper motor speed controller and a connecting wheel motion experimental system with remote laboratory. This research can be classified into engineering research. From the results of data analysis can be stated the three results of this research. First, the performance specification of the associated connecting wheel motion tool consist of a length of 54 cm, a width of 43 cm, and a height of 21 cm. Second, the average value of accuracy and of stepper motor speed controller are 99.33% and 99.08%, respectively. Third, the accuracy value for linear velocity is 99.16% for angular velocity is 99.68%. These accurate values can be classified into high category.
