Claude + Roboflow = Bike Fit Analyzer
Two open-source vision repos, one phone video, and a bike fit that went all green in 20 minutes.
I've been diving deeper into the latest vision models, and the tech coming out is next level. This weekend I wanted to see if Claude could get me an optimized bike fit using nothing but a phone video and two open-source GitHub repos.
Spoiler: it can.
The stack
Together they track every joint, draw a colored skeleton on the video (green = dialed, red = fix), and tell you the exact change to make.
What it found on me
Two things were off:
Saddle a touch high.
Cockpit way too closed, with all my weight on my hands. That explained the numb wrists.
I dropped the saddle 6mm, opened up my reach, and filmed it two more times. All green in about 20 minutes.
Research and a starting point, not a pro fit. But it beats guessing.
Try it yourself
The full guide and prompt walk you through filming, running the analysis, and reading the results.
