This Exercise Bike Charges Your Devices While You Pedal

March 23, 2025

Lithuanian startup Tukas EV has unveiled the HR Bank, an innovative exercise bike that transforms your pedaling into usable electricity.

By transforming pedaling into power, and storing on a 2000 Wh battery, the bike can do far more than make you fit.

Crafted from recycled aluminum and FSC-certified birch plywood, this eco-friendly bike not only promotes fitness but also addresses energy sustainability.

A 15-minute session can fully charge a smartphone, while an hour powers up a laptop. Beyond personal use, the HR Bank serves various settings—from corporate offices encouraging active breaks to off-grid travelers needing reliable power sources.

By integrating energy generation into daily routines, Tukas EV offers a practical approach to sustainable living.
