Steer towards a 15-year lifetime. The quickscan identifies product-performance targets as a measure, including extending the average lifetime to 15 years. The Quickscan Circular Bicycle by New Economy reports this. The environmental impact and lifespan of bicycles are rarely mapped systematically.
Steering on lifespan and repairability reduces the impact of bicycles most. This is relevant for bicycle manufacturers, designers and organisations in circular mobility.
