Personalized training at the frontier with AI
cai.bike turns your riding into training insight: load and fitness tracking, a calendar, goals, custom workouts you can ride indoors, and coaching grounded in your own data.
No password needed, just your email and a Strava account.
Automatic Strava sync
Connect once and every ride appears moments after you upload it, with power, heart rate and training load worked out for you.
Calendar
Your races and rides in one calendar, with weekly training targets that adapt to where you are in the season.
Coach chat
Ask anything, like "how was my week?" or "am I ready for Saturday?", and get answers grounded in your own rides, fitness trend and goals.
Custom workouts
Structured workouts built around your fitness and goals, ready to ride in the app or export to your trainer.
ERG mode
Ride workouts indoors with the app controlling your smart trainer.
Feels
Log daily feel and fatigue so the numbers are always read alongside how the riding actually felt.
Fitness and fatigue tracking
Chronic Training Load (CTL), Acute Training Load (ATL) and form computed from your training data, so you can see fitness building and prevent overreaching.
Goals
Set targets for races, weight or power and track progress against them. Your coach keeps them in mind when advising you.
