Athletes on a standard bicycle with substantial but less severe impairments than C1, e.g. moderate coordination impairment or above-knee amputation.
C2 athletes ride a standard bicycle and have a moderate-to-severe activity limitation. This class commonly includes riders with moderate coordination impairments or a single above-knee amputation who ride without a prosthesis. They have more function available for cycling than C1 riders but less than C3. Within the C1–C5 system, lower numbers indicate greater impairment.
