Quick Answer: If your Peloton resistance feels off or your output numbers suddenly dropped, your bike likely needs recalibration. On the Bike+, go to Settings > Home Installation > Start Recalibration. The original Bike requires contacting Peloton support for a calibration kit. After calibrating, always power off, unplug, wait 30 seconds, and plug back in for the new calibration to take effect. Peloton acknowledges up to a 10% variance between bikes is normal.

Signs Your Peloton Needs Calibration
You probably need to recalibrate if:
- Output suddenly dropped 20-50% — You used to hit 200 output on a ride and now you're getting 120 for the same effort
- Output suddenly jumped — Your numbers seem unrealistically high compared to before
- Resistance feels different — 40 resistance now feels like what 60 used to
- Your bike feels different from another Peloton — Rode at a gym or friend's house and the resistance was noticeably different at the same number
- After a technician visit — Service work can shift calibration
- After moving the bike — The move may have affected the resistance mechanism
If your metrics aren't showing at all (everything reads zero), that's a different issue — see our guide on Peloton metrics not showing.
Why Bikes Go Out of Calibration
Peloton uses a magnetic resistance system controlled by magnets around the flywheel. Over time and use:
- Magnets shift position slightly from riding vibration
- The resistance belt stretches incrementally
- Sensor components wear and readings drift
- Temperature changes can affect magnetic field strength
Peloton officially states there's approximately a 10% variance between any two bikes. So if you ride at 50 resistance on one bike, 45-55 resistance on another bike would deliver roughly the same actual force. This is normal manufacturing tolerance.
But if YOUR bike's output changes dramatically from what it used to be, that's a calibration issue worth fixing.
How to Calibrate Peloton Bike+
The Bike+ has a built-in self-calibration feature that's straightforward.
Step 1: Tap the screen and go to Settings (three dots in bottom right).
Step 2: Select Device Settings, then Home Installation.
Step 3: Tap Start Recalibration.
Step 4: Follow the on-screen prompts. The bike will ask you to turn the resistance knob to specific positions and pedal at certain speeds. The process takes about 5 minutes.
Step 5: Complete the post-calibration steps below — this is critical.
How to Calibrate Original Peloton Bike
The original Peloton Bike doesn't have a self-calibration feature in the settings menu. You have two options:
Option 1: Contact Peloton Support
Call Peloton at (866) 679-9129 or use online chat. They can: - Walk you through a calibration procedure over the phone - Send a calibration kit with instructions - Schedule a technician visit (may cost $100+ out of warranty)
Option 2: The Manual Check
While not a full recalibration, you can verify and partially adjust:
Step 1: Turn the resistance knob all the way to zero. Verify the screen shows 0.
Step 2: Turn it all the way to max (100). Verify the screen shows 100.
Step 3: If the endpoints are off, the resistance sensor may need adjustment. Contact Peloton support.
Step 4: Check for any obstruction near the resistance sensor by the flywheel — debris or misaligned components can cause incorrect readings.
Post-Calibration Steps
This is the step most people miss. After any calibration:
Step 1: Power off the tablet using the on-screen shutdown.
Step 2: Unplug the power cable from the bike.
Step 3: Wait 30 full seconds.
Step 4: Plug back in and power on.
This forces the system to reload the calibration data from scratch. Without this step, the old calibration values may persist in memory.
Verifying Your Calibration
After recalibrating, verify with a simple benchmark ride:
Step 1: Set resistance to 40 and maintain 80 RPM cadence for 2 minutes. Note your average output.
Step 2: Compare this to what you'd expect at those settings. At 40 resistance / 80 RPM, most properly calibrated Pelotons produce roughly 80-100 watts of output.
Step 3: If the numbers still seem wrong, repeat the calibration process. Sometimes it takes two passes.
For a more precise verification, FitSwitch's metrics overlay can display power data from the bike's sensors in real-time alongside any third-party app. If you use Zwift or TrainerRoad through FitSwitch, you can cross-reference the power readings between the Peloton and the app for an additional calibration check.
When Calibration Won't Fix the Problem
If you've calibrated and the numbers are still way off:
- Resistance sensor failure — The sensor near the flywheel has failed. Peloton support can send a replacement.
- Magnet issues — The magnets around the flywheel may have shifted too far or degraded. Requires service.
- Belt problems — A worn or stretched resistance belt affects the force curve. Listen for grinding or slipping sounds.
- Software bug — Occasionally a software issue causes metric display problems. Try a reboot or check for pending updates.
For Bike+ owners using ERG mode through FitSwitch, calibration is especially important — ERG mode relies on accurate resistance data to automatically adjust to your target power.

Frequently Asked Questions
How often should I calibrate my Peloton?
There's no set schedule. Calibrate when you notice a change in how the bike feels or a significant shift in your output numbers. For most riders, this might be once a year or after a service visit.
Does calibration affect my past workout data?
No. Recalibrating changes how the bike measures resistance going forward. Your historical workout data stays as-is on Peloton's servers. If past rides were done with bad calibration, those numbers remain — they just might not reflect your true effort.
Why does my Peloton feel different from the one at the gym?
Peloton's official 10% variance between bikes means there's a natural range. Combined with differences in bike age, maintenance history, and calibration state, two Pelotons can feel noticeably different at the same resistance setting. This is frustrating but normal.
Can I calibrate the Peloton Bike myself without calling support?
For the Bike+, yes — use the built-in Settings > Home Installation > Recalibration tool. For the original Bike, there's no self-service calibration in the menu. You need to contact Peloton support or attempt the manual endpoint check described above.
Will recalibration change my FTP score?
If your bike was significantly out of calibration, yes — your FTP will change after recalibrating because the bike is now measuring resistance differently. You should retake your FTP test after a major recalibration to get accurate power zone training.
My output dropped after a Peloton software update — is that calibration?
Not necessarily. Peloton occasionally tweaks the power curve algorithm in software updates, which can cause small output changes. If the change is dramatic (20%+), try recalibrating. If it's minor (5-10%), it may be a software adjustment that's intentional.
Can I compare my Peloton power with my outdoor bike?
Peloton power readings don't directly translate to outdoor cycling power meters. The resistance mechanism is different from real-world forces. That said, many riders find their Peloton output roughly correlates with their outdoor power when properly calibrated. Using FitSwitch to broadcast to Garmin helps track both in the same ecosystem.
Why is Peloton resistance different on every bike?
Manufacturing tolerances, magnet placement, belt tension, and sensor calibration all vary slightly between units. Peloton acknowledges up to 10% variance. Think of resistance numbers as relative to YOUR bike, not absolute values.
Does temperature affect Peloton calibration?
Extreme temperature changes can subtly affect the magnetic resistance system. If your bike is in a garage or unheated room and the temperature swings dramatically, you might notice slight changes in how resistance feels. This is normal physics — magnets behave differently at different temperatures.
