The Dual Shaft DC BO Motor with 45mm Yellow Wheels is a bundle of 2 dual-shaft BO DC motors and 4 matching 45mm yellow wheels, rated 3V to 12V, designed for compact and low-profile robot car builds using an axle-drive configuration. This dual shaft bo motor set uses the same axle-drive principle as the 65mm wheel variant covered separately — each motor drives both wheels on one axle simultaneously through dual shaft ends — but the smaller 45mm wheel diameter produces a meaningfully different robot behavior compared to the larger 65mm option.
The bo motor with wheel’s 45mm diameter reduces the chassis ground clearance and overall robot height compared to 65mm wheels, lowering the center of gravity and improving stability on smooth indoor surfaces where the extra ground clearance of 65mm wheels is unnecessary. This dual shaft dc motor bundle also produces a slower linear travel speed at the same motor RPM — since linear speed equals angular speed multiplied by wheel radius, a 45mm wheel distance per motor revolution than a 65mm wheel at identical RPM, making these robotics projects better suited for precision movement and sensor-intensive applications where slower speed aids accuracy.
the smaller 45mm wheels in this BO Motor bundle offer less obstacle-climbing ability than the 65mm wheels — this bundle suits smooth flat surfaces rather than uneven terrain where the larger wheel diameter would help clear small obstacles.
