East Bay Bicycle Coalition (now @bikeeastbay.bsky.social) formed in 1972 largely to advocate for bikes on BART. Bike East Bay’s office was the busiest hub in the entire Bay Area to pick up and drop off @connectbayarea.bsky.social petitions. Bike advocates ARE transit advocates.
Why isn't there more money and advocacy for urban buses and light rail? Everyone points to cities with strong bike culture, but they're most successful where reliable, fast, efficient mass transit reduces the need to have a car first.
