Modeling a vintage 1980’s Supercycle bicycle using Solidworks software.
In order to become more proficient in general CAD modelling, I deconstructed major components of my commuter bicycle and modeled them into major sub-assemblies. For added practice, components that would be interfacing such as bearings were given realistic dimensioning and tolerancing that would result in the types of desired fits for the given application (e.g. sliding fit, forced fit, etc.). Repeatedly disassembling and reassembling the bicycle also exemplified the importance of a design’s ease of assembly, especially in the case that it is mass produced. The vintage logos and stickers on the bicycle were also recreated via Adobe Photoshop to add to the model’s authenticity.
Every aspect of the frame sub-assembly, from the embroideries to the decals were taken into account. From here, each of the other bicycle sub-assemblies would stem from this when forming the bicycle’s final assembly. Within the head tube exists the upper and lower bearing races, which contain their respective retainers and ball bearings.
Modeled below is an XRim X404 front wheel. The first image shows an exploded view of how the retainer, bearings, bearing covers, threaded rod, inner locking nut and outer jam nut all fit into the wheel’s hub. Again, for added detail, the tire’s tread design was included on its outer surface.
