As fun as a smaller-wheeled bike, but more efficient. Plays rough, but brings the speed

The Zero AM Boost is Bird’s newest iteration of the successful Zero AM and the brand’s encouragement to outright hooliganism. Stiff as a ramrod and as unforgiving as a religious cult, what it lacks in finesse it makes up for in outright breach of the peace. Progressive geometry will keep you safe all day long, however hard you like to rumble, all for a wallet-friendly sum.
