For your workflow — CAD modelling + photorealistic renders + factory-ready STEP export — all free on Mac:

Best Free Option: FreeCAD + Blender

FreeCAD 1.0 (released late 2025) for the actual engineering model:[eufymake][youtube]

  • Fully free, including commercial use — no subscription, no limits[youtube]

  • Parametric — change one dimension, everything updates

  • Exports STEP files which factories read directly[youtube][wiki.freecad]

  • Runs natively on Mac including Apple Silicon

  • freecad.org[eufymake]

Blender for renders:style3d+1

  • Import the STEP/STL from FreeCAD

  • Cycles renderer produces photorealistic studio shots — Instagram-ready

  • Free forever, open source

  • blender.org

Alternative: Onshape (Free Tier)

Cloud-based, runs in the browser, no install. Professional parametric CAD with STEP export. The free tier requires your designs to be public (anyone can see them) — which may or may not matter at concept stage.[youtube]

Comparison

  | FreeCAD | Blender | Onshape Free -- | -- | -- | --
  1. iPad — sketch proportions and vibe in Procreate/Concepts

  2. FreeCAD on Mac — build the precise 3D model with real dimensions, STEP export for factory

  3. Blender on Mac — import model, add materials (matte black alu, carbon fibre texture), studio lighting, render hero shots for website/IG

FreeCAD has a learning curve but there are tons of bike frame tutorials on YouTube. Since you're already technical, you'll pick it up fast.[youtube]

The stereotypical fixie (fixed-gear bicycle) rider look is heavily inspired by bike messenger culture and hipster aesthetics — think functional, urban, and deliberately understated. Here's what the typical outfit involves:

Bottoms

Tops

Footwear and Accessories

The Overall Vibe

The style sits at a crossroads of skateboarder fashion and urban streetwear — practical enough for riding but deliberately not "cyclist gear". As one Reddit user put it, combining road biking with skate fashion is how you "really end up looking fixie af". The culture also emphasizes the bike itself as fashion — brightly colored frames, flashy wheels, and colored tires are part of the total image. The whole aesthetic spread globally, even stimulating fixie-inspired clothing lines in countries like China. sixthtone

Given your interest in bicycle design and engineering, you probably already spot these riders around Oslo!
