A pair of blue racing-style wheels for your robots! They have a 12mm hex connector, which is designed to be used with an adapter hub & motors! These wheels are 65mm in diameter, 25mm wide and are of a similar style as those used in RC hobby cars. Also available in silver and red. This purchase is for two wheels! Which hub do I need? Here are a couple of popular setup examples: * Combine a 25D motor with a 4mm hub adapter (as the motor has a 4mm shaft) * Combine a micro metal gearmotor with a 3mm hub adapter or this alternative hub adapter (as the motor has a 3mm shaft) You can also use these with different size motor shafts, just pick the right size hub from our selection to match the size of your motor's shaft.
