GT Bike V is a game modification (in short: mod) for Grand Theft Auto V (GTA V). The mod allows to connect a smart bike trainer or cycling power meter to the game allowing you to perform virtual rides. It supports stride based sensors and smart treadmills too if running is your thing.
The mod records your training data into a FIT file accompanied with periodic screenshots that you can later upload to Strava or your favorite training app to track your progress.
The mod features a course reader which auto drives you around Los Santos following different routes of various difficulty levels.
