creating self-sustaining energy sources within fitness facilities.

The rise and fall of spin studios in Singapore highlight the risks
of market saturation driven by artificial demand. However,
the aftermath offers a unique opportunity to innovate and
integrate sustainability into the fitness industry. By repurposing
spin bikes to reduce carbon emissions and generate renewable
energy, Singapore can set a global example of how urban Table 4. Overall projected amount and savings of the Eco-solution
