Bicycle assembly, lunch packing and recipes have all been used to introduced stoichiometry. The piece often missing from these models is the conversion from a count of number relationship (atoms or moles) to a mass relationship (g). Here, using bicycle assembly as the model, a conversion is added but it is distinct for each component in the assembly (frames/case, wheel/box and grips/Kg). This may be confusing to students. The addition of a conversion makes the model more complete, though one may need to add some explanation about the use of different reference standards for each bicycle component.
