ERG Mode for Peloton Bike+
This is the feature Bike+ riders have been waiting for. FitSwitch now enables full ERG mode on your Peloton Bike+, unlocking automatic resistance control for structured training.
What ERG Mode Does
ERG mode automatically adjusts your Peloton's resistance to maintain a target power output, regardless of your cadence. Set a target of 200 watts, and FitSwitch holds it whether you pedal at 80 RPM or 100 RPM. The motorized resistance knob on the Bike+ does the work for you.
How It Works with FitSwitch
FitSwitch now supports both FTMS (Fitness Machine Service) and ANT+ FE-C (Fitness Equipment Control) protocols. These are the industry-standard smart trainer control protocols used by virtually every cycling app and device. This means:
- Zwift can send workout targets directly to your Peloton
- TrainerRoad can execute structured intervals automatically
- Garmin watches (Fenix, Forerunner, Edge) can control your resistance via FE-C
- Any FTMS or FE-C compatible app can take control of your Bike+
Why This Matters
Without ERG mode, structured training on the Peloton requires constant manual resistance adjustments. You have to watch your power output and turn the knob every few seconds to stay on target. With ERG mode enabled through FitSwitch, you can focus entirely on pedaling while the bike handles resistance. This makes interval training, FTP tests, and recovery rides far more effective.

Live Heart Rate Overlay
You can now connect your heart rate monitor directly to FitSwitch and see your BPM displayed in real time on the Peloton screen overlay. No more glancing at your watch or chest strap display mid-ride.
How It Works
FitSwitch connects to your heart rate monitor and displays your current heart rate directly on the metrics overlay. This works alongside your existing power, cadence, and resistance data—all visible on screen while you use your favorite app.
Supported Heart Rate Monitors
Any ANT/ANT+ capable heart rate monitor works with FitSwitch, including:
- Chest straps — Polar H10, Garmin HRM-Pro, Wahoo TICKR
- Arm bands — Polar Verity Sense, Whoop, Scosche Rhythm+
- Watches — Garmin and similar smart watches
Why It Matters
Keeping heart rate visible during a ride helps you stay in the right training zone without breaking focus. Zone 2 endurance rides, threshold intervals, and recovery sessions all benefit from having your BPM front and center on the same screen as your other metrics.

Enhanced ANT+ and Bluetooth Connectivity
FitSwitch now broadcasts an expanded set of ANT+ and Bluetooth profiles, making your Peloton compatible with nearly every cycling computer, watch, and training app on the market.
New ANT+ Profiles
- ANT+ FE-C (Fitness Equipment Control) — Enables Garmin devices and other ANT+ equipment to control your Bike+ resistance and set target power. This is the same protocol used by smart trainers from Wahoo, Tacx, and others.
- ANT+ Cadence Profile — Broadcasts your pedaling RPM to Garmin watches, cycling computers, and any ANT+ receiver.
- ANT+ Power Meter Profile — Broadcasts your wattage as a standard ANT+ power meter signal, compatible with Garmin Edge, Fenix, Forerunner, and more.
New Bluetooth Profiles
- Bluetooth Cadence Profile — Better compatibility with mobile apps, Apple Watch, and Bluetooth-only devices.
- Bluetooth Power Profile — Standard Cycling Power Service broadcast for apps and devices that connect over Bluetooth.
What This Means for You
| Device or App | What FitSwitch Now Broadcasts |
|---|---|
| Garmin Edge / Fenix / Forerunner | Power, cadence, heart rate via ANT+; resistance control via FE-C |
| Wahoo ELEMNT | Power, cadence, heart rate via ANT+ |
| Apple Watch | Power, cadence via Bluetooth |
| Zwift (PC/Mac/iPad) | Power, cadence via Bluetooth or ANT+; ERG control via FTMS or FE-C |
| TrainerRoad | Power, cadence via Bluetooth or ANT+; ERG control via FTMS or FE-C |
| Strava (live tracking) | Power, cadence, heart rate via Bluetooth |
With these additions, FitSwitch turns your Peloton into a fully connected smart trainer that speaks the same language as every other piece of cycling equipment.
Smoother Third-Party App Installs
FitSwitch has been updated to better handle third-party Android apps with complex installation processes. Loading apps like Netflix, YouTube, Disney+, Spotify, Zwift, or any other Android app onto your Peloton screen is now more reliable.
What Changed
Some Android apps have multi-step install processes, split APKs, or require specific setup sequences. The FitSwitch app now handles these edge cases more gracefully, reducing failed installs and making the process smoother from start to finish.
If you had trouble installing certain apps before, give it another try with the latest FitSwitch update.
Coming Soon: Smart Heart Rate Training
We are currently testing an exciting new feature for Bike+ users: Auto-Resistance for Target Heart Rate.
How It Will Work
- Set a target heart rate (for example, 140 BPM)
- Connect your heart rate monitor to FitSwitch
- FitSwitch automatically adjusts the Peloton's resistance to keep you in that heart rate zone
- If your heart rate drops below target, resistance increases
- If your heart rate rises above target, resistance decreases
Why This Matters
Heart rate-based training is one of the most effective ways to build aerobic fitness. Zone 2 training—riding at a steady, moderate heart rate—is the foundation of endurance performance. But manually managing resistance to stay in a heart rate zone is tedious. Smart Heart Rate Training will automate this entirely, letting you set a target and ride while FitSwitch handles the rest.
Stay tuned for this feature in a future update.
Frequently Asked Questions
Do I need a Bike+ for all these features?
ERG mode and the upcoming Smart Heart Rate Training require the Peloton Bike+ because they depend on the motorized resistance knob. The heart rate overlay, ANT+ broadcasting, and Bluetooth broadcasting work on both the Peloton Bike and Bike+.
Which apps support ERG mode through FitSwitch?
Any app that supports FTMS or ANT+ FE-C smart trainer control. This includes Zwift, TrainerRoad, Rouvy, Wahoo SYSTM, and many others. Garmin watches with structured workout features also support FE-C control.
Do I need to update FitSwitch to get these features?
Yes. Fitswitch should automatically update so you have the new features. Version 2.3.0 and later have these features.
Can Garmin watches control my Peloton resistance now?
Yes, if you have a Bike+. Garmin watches that support FE-C (like the Fenix, Forerunner 955/965, and Edge series) can now control your Peloton's resistance and execute structured workouts through FitSwitch.
What heart rate monitors work with the overlay?
Any ANT+ heart rate monitor. This includes chest straps (Polar H10, Garmin HRM-Pro, Wahoo TICKR), arm bands (Polar Verity Sense, Scosche Rhythm+), and watches with heart rate broadcast mode.
Is the heart rate data also broadcast to external devices?
Yes. FitSwitch can simultaneously display your heart rate on the screen overlay and broadcast it via ANT+ and Bluetooth to cycling computers, watches, and apps.
Will Smart Heart Rate Training work with any heart rate monitor?
Yes, it will work with any heart rate monitor connected to FitSwitch. This feature is still in testing and will be available in a future update.
