After three decades of pursuing his vision for a revolutionary dual-flywheel climbing bike, inventor Marko Hansen has released a free eBook chronicling his unconventional journey through the fitness industry. The book details Hansen’s persistent efforts to introduce what he believes is a more efficient approach to total body workouts, despite lacking formal credentials in engineering or exercise physiology.
Hansen’s story begins in 1993 when he first developed the concept that two flywheels could provide superior workout efficiency compared to traditional single-flywheel spinning bikes. His invention, a stationary climbing bike featuring dual independent flywheels, represents a departure from conventional exercise equipment design. The free eBook offering provides an intimate look at the challenges faced by independent inventors attempting to break into established industries.

The narrative spans 33 years of Hansen’s life, from age 33 to 66, documenting his attempts to gain traction in the fitness marketplace. Despite securing two U.S. utility patents 29 years apart and a four-year licensing agreement with Bowflex, Hansen struggled to attract attention from major fitness industry players. His appearances at three fitness trade shows, where he was the sole exhibitor with a dual-flywheel climbing bike, failed to generate the interest he sought.
Hansen’s mantra, “Quit Spinning Your Wheel with Half a Workout. Do the Total Body Thing!” encapsulates his belief in the superiority of his design, though it found little resonance among trend-focused industry executives. Working without professional publicists or substantial funding, Hansen’s solo entrepreneurial journey became increasingly challenging as personal circumstances, including both parents entering home hospice care, added to his struggles.
The book takes an unexpected turn as Hansen and his wife decide to leave Tucson’s extreme heat for the Finger Lakes region of Central New York. Their purchase of a fixer-upper home sight unseen leads to an unplanned adventure when the property proves uninhabitable, forcing them to stay in a rural motel. Through what Hansen describes as serendipity, they eventually purchase the motel, finding temporary peace until his fitness equipment arrives from Arizona in 2019.
Rediscovering his passion for his invention, Hansen began using his own equipment regularly, losing over 80 pounds and returning to his 1976 high school graduation weight. This personal transformation led to further innovation, including the addition of spring-based oscillation to his design and the securing of a new patent.
The book serves multiple purposes, targeting fitness enthusiasts, aspiring entrepreneurs, and inventors who can learn from Hansen’s experiences. Additionally, Hansen envisions his story attracting film producers, proposing that a streaming premiere could simultaneously serve as a product launch for his fitness innovation.
Hansen’s account offers insights into the challenges faced by independent inventors navigating established industries without traditional credentials or resources. His persistence over three decades, despite minimal recognition outside Tucson, illustrates both the difficulties and determination required to bring unconventional ideas to market.
The free eBook presents Hansen’s journey with self-deprecating humor, comparing himself to “The Rodney Dangerfield of Fitness” while maintaining his conviction in the value of his dual-flywheel technology. His story encompasses not just the technical aspects of fitness innovation but also the personal costs and unexpected life changes that accompanied his entrepreneurial pursuit.
For those interested in fitness innovation, entrepreneurship, or inventor stories, Hansen’s 33-year journey offers both cautionary lessons and inspiration, demonstrating how passion for an idea can persist through decades of setbacks and lead to unexpected life transformations.
