In 2022, Drive Clean Bay Area changed its name to Ride and Drive Clean. The change reflects growing partnerships throughout California and the globe, including an initiative to partner with cities and large membership organizations for localized co-branded e-mobility campaigns. Ride and Drive Clean continues to focus on educating and encouraging consumers to switch to driving electric, but with an additional focus on e-bikes, Ride and Drive Clean recognizes that e-bikes play an important role in the transition to clean transportation. Ms. Cullen asserts that her e-bike is her favorite form of transportation, period.
