In this episode of the ImprimaturBMX podcast, Mike Hinkens has a conversation with hard-hitting BMX rider Zack Gerber in which they explore a few controversial topics including: the politics of twitter, the ethics of doing stunt shows, reasons for growing BMX, modifying as well as building spots, and realigning the demographic focus of BMX media, industry, and culture to not only grow BMX with incoming youths, but to maintain it by supporting aging riders.
