These wheels are great for robotics, custom RC vehicles, or any other project you need to get rolling. They measure 70 mm (2.75") in diameter and are designed to press-fit securely onto D output shafts with a diameter of 3 mm. They are compatible with many of Pololu's gearmotors, including Pololu's micro metal gearmotors and Pololu's mini plastic gearmotors. Two mounting holes for #4 or M3 screws make it possible to use the wheel with any of Pololu's universal mounting hubs for those screw sizes, enabling these wheels to be used with Pololu's larger metal gearmotors and stepper motors. The slots in the five spokes fit #2 or M2 screws and allow additional accessories to be mounted to the wheel such as decorations or parts of an encoder system. The included silicone tires, which feature horizontal treads for improved traction, are also available separately.
The pictures below show this wheel with a universal mounting hub for 4mm shafts installed so it can work with Pololu's 20D or 25D metal gearmotors.
