Cyclist: Cycling Watch Face

A digital watch face built for road cyclists, gravel riders, and indoor trainers on Wear OS. Designed around an aerodynamic rider silhouette at a 15-degree forward tilt, it turns your wrist into a clean, glanceable cycling cockpit that reacts to your real-time Heart Rate (HR).

LIVE 5-COLOR HEART RATE WIND TRAIL
Behind the rider, a three-line aerodynamic slipstream scales and changes color in real time based on your current HR:
- Warm-Up Scaling (Grey): At rest, the Grey wind trail stays compact and subtle. As your heart rate rises from rest toward your active warm-up threshold, the slipstream smoothly lengthens and brightens to full size.
- Intensity Color Shifts (Grey, Blue, Green, Orange, Red): As your effort builds, the full-length wind trail shifts across five distinct training colors:
* Grey: Light effort and warm-up
* Blue: Endurance pace
* Green: Tempo and aerobic effort
* Orange: Threshold effort
* Red: Peak high-intensity effort
- Automatic Clean View: When the watch is off your wrist or no HR reading is available, the wind trail and BPM readout hide automatically.

10 BUILT-IN HEART RATE PROFILES (MAX HR & LTHR)
Pick the training model that matches your physiology directly in the watch face customization menu:
- 5 Maximum Heart Rate (Max HR) Profiles: 200, 190, 180, 170, and 160 Max HR (Grey reaches full length at 50% of Max HR, then shifts to Blue, Green, Orange, and Red at 60 / 70 / 80 / 90%).
- 5 Lactate Threshold Heart Rate (LTHR) Profiles: 180, 170, 160, 150, and 140 LTHR (Grey reaches full length at 55% of LTHR, then shifts to Blue, Green, Orange, and Red at standard cycling LTHR thresholds of 81 / 90 / 94 / 100%).

6 BIKE FRAME COLORWAYS & MATCHING ACCENT ARCS
Customize the rider and wheel accents independently or match them together:
- 6 Bike Styles: Flame (Orange), Aero (Cyan), Pulse (Pink), Volt (Neon Yellow-Green), Podium (Gold), and Titanium (Silver-White).
- 6 Arc Theme Colors: Match or mix the progress arcs inside the wheels and battery gauge with any of the six signature colors.

INTEGRATED WHEEL COMPLICATIONS & LIVE DATA
Every data field is positioned to follow the geometry of the bike:
- Rear & Front Wheel Complications: Two circular complication slots sit directly inside the rear and front wheels. Supports Ranged Value, Goal Progress, Short Text, Small Image, and Icon complications. Progress arcs wrap around the inside of the tires like spinning rims (Rear wheel defaults to Step Count; Front wheel defaults to Empty for a clean look until you add a metric).
- Angled Cockpit Readouts: High-contrast italic digital time (12h/24h auto-sync) and date aligned with the rider's sightline.
- Live Weather & UV Bar: Displays current temperature (C or F), weather condition icon, and UV index along the top arc when weather data is available.
- Bottom Battery Gauge: Curved battery progress bar with charging bolt along the lower bezel.
- 2 Custom App Shortcuts: Tap targets over the Weather and Heart Rate areas let you assign quick shortcuts to your favorite fitness, workout, or weather apps.

BUILT WITH WATCH FACE FORMAT (WFF)
- Native Wear OS Watch Face Format (WFF v2) with zero background code for smooth rendering and minimal battery impact.
- True black (#000000) AMOLED background and a dedicated dim Always-On Display (AOD) mode that preserves the bike silhouette, time, date, and low-opacity wind trail while saving power.
- Localized on-watch customization labels in 11 languages: English, German, French, Spanish, Italian, Dutch, Portuguese, Japanese, Korean, Simplified Chinese, and Traditional Chinese.

Compatibility: Requires Wear OS 5 or newer (API 34+).
