The E-Bike Share Act directs the Secretary of Transportation to create a competitive grant program that provides funding to establish electric bicycle sharing services in disadvantaged communities across the United States. Eligible applicants include state and local governments, metropolitan planning organizations, nonprofits, colleges, public housing agencies, and parks departments that partner with local governments to host these services. Grant funds can be used to purchase electric bikes, install charging infrastructure, conduct community outreach, offer subsidized memberships, and cover operational costs, with individual grants capped at five million dollars and funds available for five-year spending periods. The bill authorizes $100 million in annual funding from 2024 through 2033 and requires grant recipients to submit yearly reports tracking usage data, operating costs, emissions reductions, and customer satisfaction. The legislation prioritizes projects that demonstrate community engagement, ensure cyclist safety through improved roadway design, purchase domestically assembled bikes with U.S.-manufactured batteries, and show long-term economic viability.
