Inspired by bike parties in surrounding areas, the East Bay Bike Party brings together revelers and cyclists alike for monthly rides through the streets of Berkeley, Oakland, and elsewhere. And no, it's not the same thing as Critical Mass. Bike party rides are organized with designated routes and leaders. Bike partiers make a point to stop at all stop lights and only take up one lane on the road. Otherwise, the rules of the Bike Party are pretty simple: arrive with a bike, dancing shoes, and road rule-abiding, non-confrontational, friendly vibes. Oh yeah, and be prepared to party.
