The ThinkRider X7 is a premium direct-drive smart bike trainer designed to deliver a realistic, highly immersive indoor cycling experience. Recognized for its unique structural design that allows for natural side-to-side movement, the X7 balances cutting-edge performance metrics with frame-protecting comfort. Below is the complete technical and commercial specification breakdown for your product listing:

1. Performance & Resistance Metrics

- Maximum Power Output: 2,500 Watts (Sustained peak capacity to handle high-output sprinting).
- Maximum Simulated Incline: 20% (Accurately reproduces steep alpine climbs in virtual environments).
- Power Accuracy Rating: ±2% (High-precision strain gauge system providing dependable training data).
- Resistance Type: Electromagnetic coil damping with electronic automated control.
- Downhill Simulation: Passive (Damping scales down to mimic descents; does not actively spin the flywheel).

2. Physical Design & Ride Feel

- Frame Architecture: Y-shaped structural carbon steel base with an integrated elastic rocking system.
- Lateral Sway Motion: ±5° of side-to-side flexible movement (Mimics natural outdoor riding kinematics, alleviates pelvic fatigue, and minimizes stress on the bicycle’s rear carbon fiber triangle).
- Flywheel Weight: 5.7 kg (Dynamic steel construction optimized for realistic kinetic inertia).
- Noise Level: ≤58 dB at 30 kph (Virtually silent belt-driven operation; only your bike’s drivetrain sound is audible).
- Gross Weight: 22 kg / 48.5 lbs (Solid base layout preventing tipping or sliding during high-torque efforts).
- Footprint Dimensions: 860 mm x 560 mm x 480 mm (Unfolded).
- Folding Mechanics: Non-folding frame design; requires detached storage or a designated static training space.

3. Connectivity & Software Protocol

- Wireless Transmission: Dual-band Bluetooth 4.0 / BLE and ANT+ wireless protocols.
- Control Standards: ANT+ FE-C (Fitness Equipment Control) and FTMS Bluetooth protocol.
- Smart App Compatibility: Fully compatible with Zwift, Wahoo SYSTM, TrainerRoad, Rouvy, FulGaz, Kinomap, and RGT Cycling.
- Operating Systems: iOS, Android, macOS, and Windows.
- Firmware Updates: Wireless updates and manual spin-down calibrations handled via the proprietary ThinkRider Tools mobile app.

4. Drivetrain & Bike Compatibility

- Supported Wheel Sizes:
  - - Road: 650c, 700c.
    - MTB: 24″, 26″, 27.5″, 29″.
- Axle Configurations (Included In-Box):
  - - 130mm and 135mm Standard Quick Release (QR).
    - 12x142mm and 12x148mm Thru-Axle (Boost spaced).
- Cassette Freehub Type: Shimano/SRAM standard 9/10/11-speed hyperglide (HG) splined freehub body out of the box.
- Drivetrain Compatibility Notes:
  - - Shimano 12-Speed: Compatible with standard 12-speed road cassettes (HG splined); not native to off-road Micro Spline.
    - SRAM 12-Speed: Requires a separate XDR freehub driver accessory for XD/XDR cassettes.
    - Campagnolo: Requires a specialized Campagnolo freehub adapter (sold separately).

5. Electrical & Structural Requirements

- Power Input: 100-240V AC, 50-60Hz external power supply brick (Universal voltage compatibility).
- Maximum Rider Weight Limit: 100 kg / 220 lbs.
