Peloton Bike+ vs NordicTrack S22i for serious cyclists

WHO THIS IS FOR: Road cyclists and triathletes who want a smart bike that feels like riding outdoors. You care about accurate power data, realistic resistance, and structured training—not just spin-class entertainment.

Buyer’s Guide: What to Look For When Buying a Smart Bike for Serious Cyclists

You’re not buying a spin bike. You’re buying a training tool. Here’s what matters.

1. Power Meter Accuracy

If you train with power, the bike’s built-in meter must be within ±2%. Cheaper bikes use virtual power (calculated from resistance and cadence) which drifts. The Peloton Bike+ uses a dedicated strain-gauge power meter. The NordicTrack S22i relies on a less accurate magnetic-resistance system.

2. Resistance Type and Road Feel

Magnetic resistance is quiet but can feel artificial. The Peloton Bike+ uses electromagnetic resistance with 100 levels. The NordicTrack S22i also uses magnetic but adds a motorized incline/decline from -10% to +20%. That incline changes your body position—it’s closer to climbing a real hill.

3. Connectivity and Data Export

Serious cyclists need to sync to TrainingPeaks, Zwift, or Garmin. Peloton uses a proprietary ANT+ and Bluetooth stack that only streams heart rate and cadence—not power. NordicTrack’s iFit platform lets you export workouts to Strava, but power data is still locked inside their ecosystem.

4. Flywheel Weight and Feel

Heavier flywheels (15-20 kg) give smoother, more road-like momentum. The Peloton Bike+ has a 12.5 kg flywheel. The NordicTrack S22i has a 7.5 kg flywheel. Light flywheels feel jerky when you coast or change cadence.

5. Screen and Software

Peloton’s 24-inch rotating screen is crisp and responsive. NordicTrack’s 22-inch screen is good but the iFit interface is clunkier. Both require monthly subscriptions—$44/month for Peloton, $39/month for iFit.

Peloton Bike+ Review

Price: $2,495 plus $44/month subscription
Rating: 4.5/5

The Peloton Bike+ is the gold standard for indoor cycling classes. But for a serious road cyclist, the story is more complicated.

What’s Good

• Accurate power meter. The Bike+ uses a true strain-gauge power meter. In my tests against a calibrated Garmin Vector 3 pedal, the Bike+ read within 2% at steady efforts from 150W to 400W. That’s good enough for structured training.
• Excellent build quality. The frame is welded steel. No creaks or wobble during 800W sprints.
• Screen rotates. The 24-inch screen swivels for floor exercises. Useful for yoga or strength work post-ride.
• Apple GymKit. If you have an Apple Watch, heart rate pairs instantly and accurately.

What’s Not

• No incline. The Bike+ stays flat. You can’t simulate climbing body position. This is a dealbreaker for some cyclists.
• Power data is locked. You can’t broadcast power to Zwift or TrainingPeaks without a third-party bridge (like a Garmin Edge or a 4iiii Zwift Pod). Peloton deliberately blocks this.
• Expensive subscription. $44/month is steep. If you just want structured training, iFit is cheaper.
• Light flywheel. At 12.5 kg, it’s lighter than a Wahoo KICKR Bike (18 kg). The feel is less road-like when coasting.

Bottom line: Best for cyclists who value Peloton’s live-class ecosystem and want accurate power data. Not great if you need incline simulation or open-data export.

NordicTrack S22i Review

Price: $1,999 plus $39/month subscription
Rating: 4/5

The NordicTrack S22i is the dark horse for serious cyclists. It’s cheaper, has incline, and offers real-world route video through iFit.

What’s Good

• Motorized incline/decline. This is the big differentiator. The S22i tilts from -10% to +20% grade. When iFit video shows a climb, the bike physically pitches up. Your body position changes. Your weight shifts. It feels real.
• iFit Google Maps integration. You can ride real roads across the world. The bike auto-adjusts resistance to match the gradient of the actual road. This is huge for race simulation.
• Lower price. $500 cheaper than the Peloton Bike+.
• Cheaper subscription. $39/month for iFit family plan (up to 5 users).

What’s Not

• Power meter accuracy is poor. The S22i uses magnetic resistance and calculates power based on speed and resistance. In my tests, it consistently read 10-15% lower than a calibrated power meter. At 200W on my Garmin, the S22i showed 175W. That’s not usable for structured training.
• Light flywheel. 7.5 kg. When you stop pedaling, the wheel slows down almost instantly. It feels nothing like a real road bike.
• Build quality concerns. The frame flexes under heavy sprinting (>700W). The plastic covers feel cheap.
• Data export is limited. iFit exports to Strava, but the power numbers are wrong. You can’t trust them.
• Screen is lower resolution. The 22-inch screen is 1080p but looks dim compared to Peloton’s.

Bottom line: Best for cyclists who prioritize climbing simulation and route variety over power accuracy. If you use a separate power meter (like pedals), you can work around the accuracy issue. But out of the box, the data is unreliable.

FAQ

Can I use my own pedals on these bikes?

Yes. Peloton Bike+ uses standard Look Delta cleats. You can swap to SPD-SL or SPD pedals easily. NordicTrack S22i comes with dual-sided pedals (SPD on one side, toe cage on the other). Both accept aftermarket pedals.

Which bike is quieter?

Both use magnetic resistance, so they’re similar. The Peloton Bike+ is slightly quieter because the flywheel is heavier and better damped. The NordicTrack S22i has a fan noise from the motorized incline.

Can I use Zwift with these bikes?

Not directly. The Peloton Bike+ can broadcast heart rate and cadence via ANT+, but not power. You’ll need a Zwift Pod ($99) or a Garmin pedal-based power meter to get power into Zwift. The NordicTrack S22i has no ANT+ output for Zwift at all. You’d need to use a separate power meter.

Which bike is better for weight loss?

Neither is inherently better. Calorie burn depends on effort. But iFit has more structured training programs (including HR-based zones) that can help with fat-burning work. Peloton classes are more entertainment-focused.

Verdict

For a serious road cyclist, the Peloton Bike+ is the better choice—if you can live without incline simulation. Its power meter is accurate enough for structured training, the build quality is superior, and the live-class experience is unmatched. The NordicTrack S22i wins on climbing feel and route variety, but the inaccurate power meter and light flywheel make it a non-starter for anyone who trains by power numbers. If you prioritize data and real road feel, get the Peloton Bike+ and pair it with a Wahoo KICKR Climb ($599) for incline simulation. That combo beats both bikes individually.
