SHENZHEN, China, Jan. 1, 2026 /PRNewswire/ -- Fitkol today announced the launch of its NB Series of AI-powered treadmills, featuring SportMind™, an LLM Agent–driven intelligent training system designed to adapt running sessions in real time based on physiological feedback. The Early Access program began on December 26, 2025, with the official product launch scheduled for February 2, 2026.

The Fitkol NB Series includes two models — NB2 and NB6 — built around a body-first training philosophy emphasizing adaptive pacing, intuitive interaction, and joint-conscious control. SportMind™ adjusts speed and incline based on heart-rate and cadence data to reduce cognitive load and support consistent training.

Upon launch, the Fitkol NB Series will be available in the United States, Canada, Germany, France, and other selected markets. Availability may vary by region.

Key Features of the Fitkol NB Series

• Effortless Setup: Just press the "AI" button and let SportMind™ handle the rest—so you can simply focus on the run, with hands-free voice interaction enabling speed or incline adjustments.
• Adaptive Intelligence: Powered by an LLM-based agent, SportMind™ analyzes user profiles and real-time heart-rate data to adjust speed and incline toward an optimal training zone.
• Joint-Safe Rhythm Control: Heart-rate-based pacing helps reduce joint stress by avoiding abrupt speed changes and maintaining stable training intensity.
• Built-to-Run Hardware: The NB Series features a 5.0HP German Bosch brushless motor for sustained power and durability, paired with a 20-inch commercial-grade running surface.

The system is designed to support a range of training needs, from everyday fitness and weight-management workouts to endurance-focused training, serving both beginners and more advanced runners.

"SportMind™ was developed to make running easier and more scientifically guided." a Fitkol engineer said. "With the NB Series, our goal was to simplify interaction while maintaining effective and safe training intensity."
