Wahoo Kickr 2025: Core 2, Zwift One & Bike Pro

Wahoo’s gear for indoor training continues evolving. With the Core 2 series and the Bike Pro, they’ve pushed new features (WiFi, faster power data, virtual shifting, and more) deeper into their product line. These aren’t just modest refreshes — they shift how mid-tier and premium indoor setups behave. In this post, we’ll break down what’s new, what’s stayed the same, and which model might suit you best.

Wahoo Kickr Core 2 & Kickr Core 2 Zwift One

These are two variants in the same family — one “bare” trainer core, and one “bundled” with Zwift’s Cog + Click system for virtual shifting. Let’s treat them together, then highlight differences.

Specs & What’s New

• Resistance: Electromagnetic
• Max power: 1,800 W
• Power accuracy: ±2%
• Max simulated grade: 16%
• Max simulated decline: –10%
• Dimensions: ~59.7 × 52 × 47 cm
• Weight: ~14.1 kg with cassette (13.7 kg without)
• Hub compatibility: 130/135 QR, 12×142 and 12×148 thru-axle, adapters included
• Cassette / Cog: 11-speed cassette or Zwift Cog + Click version
• Connectivity / Features: WiFi for firmware updates, “Race Mode” for faster power data, multi-colour LED indicators, color-coded legs for easier setup, compatibility with Wahoo accessories

The Core 2 retains essentially the same 5.4 kg flywheel as before, so the “feel” inertia is similar to original Core, even though the overall unit is lighter.

Ride & Performance

• Accuracy & Consistency: Performs within ±2% in both ERG and simulated modes.
• ERG & Interval Behavior: Slight overshoot/lag in fast transitions, acceptable for most users.
• Setup / Ease of Use: Color-coded legs and LED indicators reduce mistakes.
• Noise / Feel: Quiet and smooth for Core-class trainers.
• Zwift Cog / Virtual Shifting: Accurate and responsive plug-and-play feature in Zwift One version.

Differences: Core 2 vs Core 2 Zwift One

The Zwift One bundle comes preinstalled with the Zwift Cog and Click controller for virtual shifting. The plain Core 2 allows users to install a traditional cassette.

Strengths & Trade-offs

Pros:

• Advanced features (WiFi, Race Mode) from higher-tier models
• Good power (1,800 W) vs cost/value
• Compatibility with many bikes and accessories
• Optional virtual shifting via Cog + Click
• Easier setup with color coding & LEDs

Cons:

• 1,800 W max may limit serious sprinters
• Accuracy ±2% is not top-tier
• Feel won’t match real bike drivetrain nuances
• Multi-user households require calibration for virtual shifting

Wahoo Kickr Bike Pro

The Kickr Bike Pro is a full smart bike, replacing or sitting alongside the previous Kickr Bike V2.

Specs & Key Features

• Power accuracy: ±1%
• Max power / resistance: 2,500 W
• Max gradient simulation: 20% incline, –15% decline
• Connectivity: Bluetooth, ANT+, ANT+ FE-C, WiFi, Direct Connect
• Compatibility: Wahoo accessories (e.g., Kickr Climb)
• Fit & adjustability: Multiple points of adjustment, updated touchpoints

Ride Experience & Comparisons

• Integrated feel without mounting own bike
• Immersive gradient simulation with incline & decline
• Tight accuracy for performance-oriented riders
• Stable platform and realistic shifting/gear feel
• Fixed footprint, permanent space required

Strengths & Trade-offs

Pros:

• All-in-one indoor bike experience
• High accuracy & resistance range
• Immersive gradient simulation
• Fewer setup hassles
• Premium components / ergonomics

Cons:

• Higher price than Core 2 + bike combo
• Fixed footprint; not stowable
• Lower ROI if you already own a trainer setup
• Upgrades may be needed for comfort

Which One Should You Pick?

Conclusion

Wahoo’s latest releases blur the line between premium and mid-tier gear. The Kickr Core 2 series brings class-leading features like WiFi, Race Mode, and smart gear shifting deeper into their trainer range. Meanwhile, the Kickr Bike Pro refines Wahoo’s smart bike offering with updated components while retaining high-end appeal.

For most riders, the Core 2 Zwift One hits the sweet spot of performance, flexibility, and convenience. Serious indoor cyclists ready to commit fully will find the Bike Pro a future-proof option.
