About
BikeFit IA is a free AI-driven cycling posture analysis platform designed to help cyclists of all levels achieve an optimal bike fit from home. By leveraging computer vision and artificial intelligence, the tool analyzes images or video footage of a rider on their bike — whether on a home trainer, turbo trainer, or rollers — and automatically measures critical body angles such as knee extension, hip angle, and torso lean. These measurements are then used to provide personalized recommendations for saddle height, handlebar reach, and overall riding position. The platform caters to indoor cyclists using platforms like Zwift, as well as road and gravel riders looking to improve comfort, power output, and aerodynamics. Unlike expensive in-person bike fitting services or subscription-based alternatives, BikeFit IA offers its core analysis completely free, making professional-level insights accessible to amateur and recreational cyclists. The tool is particularly useful for optimizing FTP (Functional Threshold Power) output by ensuring the rider's body mechanics are efficient and injury-free. Key use cases include DIY bike fitting at home, fine-tuning position before a cycling event, and cross-referencing a previous professional fit. BikeFit IA targets everyday cyclists, indoor training enthusiasts, and coaches looking for an affordable postural assessment tool.
