Electric Buses for Public Transit Agencies

The transit industry is rapidly transitioning to battery-electric vehicles, with more and more cities making commitments to zero-emission transportation. That’s why Proterra builds our own ZX5 electric transit bus with industry-leading range and also partners with transit bus manufacturers to electrify their transit buses, creating battery-electric buses designed to meet the needs of public transit fleets throughout North America and beyond. Electric buses powered by Proterra provide the perfect solution for public transit fleets to reduce emissions and improve air quality in the communities they serve.
