Two-Wheelers & Mobility parts lists
BOMwiki maps 43 two-wheelers & mobility products, each exploded into a recursive bill of materials: 9,582 parts in total, down to individual fasteners and cells. The largest is the electric motorcycle at 1,278 parts across 15 top-level assemblies; the simplest is the quickshifter at 15. Across the domain the same components recur: fastener set, ball bearing, wire bundle and bare PCB appear in most of these machines, and each is a single shared page here, so a correction to one fixes every product that uses it. Open any product for its parts diagram, the function of each part, and the full bill of materials.
