Bike Dynamics turns your Apple Watch into a sensor for mountain biking. Mount it securely to your handlebar, start a ride and turn raw motion, GPS and bike data into a detailed picture of what happened on the trail. Track jumps, corners, speed changes, control moments and repeated trail sections. Replay your ride on a synchronized map and timeline, compare runs and build a personal performance archive over time. RIDE ANALYSIS • Replay your full ride with map, speed and event timeline • Detect jumps, corners and control moments • Track airtime, jump distance and takeoff speed • Review speed changes and slowdown zones • See ride summaries and standout moments TRAIL INTELLIGENCE Bike Dynamics can recognize repeated trail sections across your rides. Compare matched runs, see your fastest time and understand how consistently the same features were detected. RECORDS Build a personal archive across your rides, including: • Jump distance • Airtime • Takeoff speed • Drop and trajectory metrics • Backwheel and control metrics • Ride and trail performance APPLE WATCH RECORDING For the highest recording quality, mount your Apple Watch rigidly to the handlebar. Bike Dynamics uses high-frequency motion data together with GPS and, when available, compatible bike telemetry. Supported setups include: • Apple Watch + bike telemetry • Apple Watch only • iPhone-only recording with reduced precision Compatible bike data depends on the hardware and available Bluetooth services. AI COACH Discuss a ride directly with Coach. Bike Dynamics can use your ride data as context to help you reflect on technique, confidence, consistency and possible next steps. Coach uses supported Apple Intelligence models on compatible devices. Your rides remain the basis of the conversation. HONEST DATA Bike Dynamics distinguishes between measured, calculated and estimated values. Metrics are only shown when the available sensor data supports them. EXPORT You can directly export your rides to strava. Only two clicks required. Bike Dynamics is built for riders who want more than a GPS track, from downhill and enduro sessions to jump lines, repeated trails and everyday progression.
