GoBikeFit — AI Bike Fitting from a Photo
Your personal bike fit, powered by AI. Snap a photo of yourself on your bike and get instant, pro-level fit analysis in minutes — no studio, no appointment, no expensive session required.
A proper bike fit makes every ride more comfortable, more efficient, and easier on your body. GoBikeFit brings that to your phone.
How it works
1. Take a couple of side-view photos of yourself pedaling.
2. On-device AI detects your riding position and joint angles.
3. Get clear, personalized recommendations you can act on right away.
What GoBikeFit analyzes
• Saddle height — measures your knee bend at the bottom of the pedal stroke and tells you whether to raise or lower the saddle to protect your knees and pedal efficiently.
• Saddle setback (fore-aft) — checks how your knee tracks over the pedal with the crank forward, so your weight sits in the right place.
• Reach & drop — evaluates your torso and elbow angles to balance comfort and aerodynamics in your cockpit.
Each result comes with a plain-English explanation and a specific suggestion — not just numbers.
Private by design
All analysis runs entirely on your device. Your photos never leave your phone, and no internet connection is required to use the app. Nothing is uploaded, ever.
Why riders love it
• Instant results in minutes
• Understand why each adjustment matters
• Re-check your fit any time you change your setup
• No cables, sensors, or special equipment — just your phone
Whether you're chasing comfort on long rides, dialing in a new bike, or fixing nagging knee or back pain, GoBikeFit helps you ride better.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
We've improved bike-fit analysis accuracy and reliability!
• More accurate knee, torso and knee-over-pedal readings, especially on portrait photos
• Both photos are now measured on the same leg for consistent results.
• Clearer guidance when a photo can't be measured (wrong leg down, crank not level, angled camera)
• Fewer false "not a side view" rejections
• Bug fixes and stability improvements
