A hub assembly includes a housing, retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle sleeve including an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, second end, and conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.
