👉 The term "counterwheel" refers to a type of bicycle wheel that is designed for use on flat surfaces and has a small diameter, typically between 30-40mm. Counterwheels are commonly used in recreational or leisure cycling, especially in urban areas where there may be limited off-road terrain. They are generally less efficient than full-size wheels due to their smaller size and higher center of gravity, but they offer the advantage of being easier to ride on flat surfaces.
