The successful introduction of a new bike-sharing service called Spin some months later only raised additional questions about Pronto's demise. The proven success of bike-sharing companies in other US cities known for rainy weather and steep hills meant that Seattle's climate and terrain were not to blame; instead. Pronto's critics pointed the finger at serious issues with the locations of its docking stations. Spin's bikes could be unlocked using a smartphone and left anywhere within an authorized area, and Spin enrolled many users in areas that had lacked access to Pronto when it started operating. Furthermore, Pronto's network had failed to adequately provide service in areas ignored by Seattle's existing public transportation system. JULI ul
