ZoneLight: Training Zones

Transform your training with real-time visual zone feedback. ZoneLight connects your power meter or heart rate monitor to LED light bars and strips, showing you exactly which training zone you're in - instantly.

Perfect for indoor cycling (app agnostic so works with Zwift, Rouvy, TrainerRoad, Wahoo SYSTM, MyWhoosh, etc), indoor running, or any structured workout where staying in the right zone matters. Can also be used as a standalone monitor (again, showing the zones) for HRM & Power - great for seeing your HR exploding when the gym spin class is in full swing!

TRAIN IN THE RIGHT ZONE, EVERY TIME

ZoneLight turns your workout space into a visual training environment. Connect your power meter or heart rate monitor, add LED lights, and see your training zones light up in real-time - no more squinting at screens during hard intervals.

INSTANT VISUAL FEEDBACK • LED lights change colour as you move between zones • Power zones based on your FTP (6 zones) • Heart rate zones based on your Max HR (5 zones) • Built-in display shows current power/heart rate and zone
