A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a 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.

1. A wheel assembly comprising: a wheel including an axle bore, anda pin sleeve includinga first end in fluid communication with the axle bore,a second end, anda conduit between the first end and the second end;a retaining member in the conduit and configured to operatively engage a groove in an axle;a biasing element in the conduit and configured to bias the retaining member towards the axle bore; anda hand maneuverable release mechanism configured to displace the retaining element away from the axle bore upon radially inward movement of a tab of the hand maneuverable release mechanism, the hand maneuverable release mechanism remaining with the wheel assembly during operation of the wheel assembly. 2. The wheel assembly of claim 1, further comprising a restraining element configured to inhibit the biasing element from exiting the second end of the pin sleeve. 3. The wheel assembly of claim 2, wherein the restraining element comprises a plug mechanically coupled to the second end of the pin sleeve. 4. The wheel assembly of claim 2, wherein the restraining element comprises a deformation in the pin sleeve. 5. The wheel assembly of claim 4, wherein the deformation is proximate to the second end of the pin sleeve. 6. The wheel assembly of claim 4, wherein the deformation extends substantially around a circumference of the pin sleeve. 7. The wheel assembly of claim 4, wherein the deformation comprises one or more protrusions extending into the pin sleeve. 8. The wheel assembly of claim 4, wherein the deformation comprises a plurality of legs extending into the conduit. 9. The wheel assembly of claim 8, wherein the plurality of legs comprises four legs that are spaced by about 90° around a circumference of the pin sleeve. 10. The wheel assembly of claim 1, further comprising tread mechanically coupled to the wheel. 11. The wheel assembly of claim 10, wherein the wheel comprises plastic and the tread comprises at least one of thermoplastic elastomer and thermoplastic urethane. 12. The wheel assembly of claim 10, wherein the tread has a smooth surface. 13. The wheel assembly of claim 1, wherein the hand maneuverable release mechanism comprises: a tab configured to be manipulated by a hand of a user; anda lifter coupled to the tab, at least a portion of the lifter in the pin sleeve, the lifter configured to interact with the retaining element. 14. A method of making a wheel assembly, the method comprising: inserting a part of a hand maneuverable release mechanism in a side of a pin sleeve of a wheel of the wheel assembly;inserting a retaining element in an end of the pin sleeve, the hand maneuverable release mechanism configured to displace the retaining element upon radially inward movement of a tab of the hand maneuverable release mechanism;inserting a biasing element in the end of the pin sleeve;deforming the end of the pin sleeve, wherein during deforming the end of the pin sleeve the wheel assembly includes, in the pin sleeve, the retaining element, the biasing element, and a the part of the hand-maneuverable release mechanism, the wheel including an axle bore in fluid communication with another end of the pin sleeve and a conduit extending between the end and the another end, wherein after deforming the end of the pin sleeve the biasing element is inhibited from exiting the end of the pin sleeve. 15. The method of claim 14, further comprising inserting a portion of the hand-maneuverable release mechanism in the pin sleeve through an orifice in the pin sleeve prior to deforming the end of the pin sleeve. 16. The method of claim 14, further comprising inserting a portion of the hand-maneuverable release mechanism in the pin sleeve, wherein inserting the portion comprises: inserting the portion of the hand-maneuverable release mechanism through a channel in the pin sleeve; androtating the hand-maneuverable release mechanism. 17. The method of claim 14, wherein deforming the end of the pin sleeve comprises deforming substantially around a circumference of the pin sleeve. 18. The method of claim 14, wherein deforming the end of the pin sleeve comprises forming one or more protrusions extending into the pin sleeve. 19. The method of claim 14, wherein deforming the end of the pin sleeve comprises forming a plurality of legs extending into the conduit. 20. The method of claim 19, wherein forming the plurality of legs comprises spacing the legs by about 90° around a circumference of the pin sleeve. 21. The method of claim 14, further comprising: forming the wheel in a first shot of a molding process; andmechanically coupling a tread to the wheel in a second shot of the molding process. 22. The method of claim 14, wherein the part of the hand maneuverable release mechanism comprises a lifter, the lifter coupled to the tab. 23. A method of making a wheel assembly, the method comprising: occluding a pin sleeve of a wheel, wherein during occluding the pin sleeve the wheel assembly includes, in the pin sleeve, a retaining element, a biasing element, and a part of a hand-maneuverable release mechanism, the hand-maneuverable release mechanism configured to displace the retaining element away from the axle bore upon radially inward movement of another part of the hand maneuverable release mechanism, the wheel including an axle bore in fluid communication with a first end of the pin sleeve and a conduit extending between the first end and the second end, wherein after occluding the pin sleeve the biasing element is inhibited from exiting the second end of the pin sleeve. 24. The method claim of claim 23, wherein occluding the pin sleeve comprises deforming the pin sleeve. 25. The method of claim 24, wherein deforming the pin sleeve comprises forming a deformation proximate to the second end of the pin sleeve. 26. The method claim of claim 23, wherein occluding the pin sleeve comprises mechanically coupling a plug to the end of the pin sleeve. 27. The method of claim 23, further comprising: forming the wheel in a first shot of a molding process; andmechanically coupling a tread to the wheel in a second shot of the molding process. 28. The method of claim 23, wherein the hand maneuverable release mechanism comprises: a tab manipulatable by a user, the tab comprising the another part; anda lifter coupled to the tab, the lifter comprising the part.
