10 years #uphillflow

Be curious. Climb up trails. Embark on long journeys and adventures. Defy gravity. That's what Uphill Flow means to us. It has been motivating us for the past ten years.

In 2013, the concept of Uphill Flow was born when Claus Fleischer, CEO of Bosch eBike Systems, and eMTB pioneer Stefan Schlie challenged gravity and rode their eBikes uphill on the trails of Stuttgart, all while maintaining their flow. Just one year later, the Uphill Flow movement had already captured the hearts of an entire community and it continues to do so to this day.

Uphill Flow refers to the special moment during the uphill ride where the perfect balance between effort and ease is achieved.

The Uphill Flow triangle perfectly balances the challenge of the trail (top), individual riding ability (bottom left), and personal demands (bottom right). When you fully utilize these three parameters and are challenged just enough, you can experience the sensation of Uphill Flow.

„The 'aha' moment of suddenly being able to effortlessly conquer uphill slopes that seemed impossible before was tremendous.“

„The flow window is the range of effort between being under-challenged and overburdened.“
