Travel routes

CalTrans Bike Shuttle[]

Most riders crossing the bay from the West to travel to the Berkeley Critical Mass ride take the cheapest way over to Oakland, the $1.00 CalTrans bike shuttle, a 15 passenger microbus, operated by the California Department of Transportation, which tows a bike carrying trailer which offers service from San Francisco to the MacArthur Bart Station. Riders then ride north on Telegraph Avenue, to Shattuck Avenue, to Downtown Berkeley.

Effective Dec. 1, 2013, bikes are allowed on BART at all times. See BART bike rules:


Other riders take the Oakland/Alameda Ferry from the Ferry Building in San Francisco to the Ferry Terminal on Water Street at Jack London Square, for a fare of $6.00 dollars each way, before riding to the ride meet-up location. There are no bicycle blackout restrictions whatsoever on the Oakland/Alameda ferry, and riders may bring bikes aboard all of the fleet's ferries. There are bike racks inside the ferry cabins. Also it's generally thought that, though the CalTrans bike shuttle's 15 passenger microbus and trailer sometimes fills up with cyclists, the ferry boat rarely is so crowded that a cyclist can't make it aboard with his or her bike.

The 5:20p.m. ferry leaves San Francisco's Ferry Building at 4:10PM and arrives at 4:40PM. The 5:20p.m. leaves the SF Ferry Building and arrives at Oakland's Jack London Square Ferry Terminal at 5:50p.m.

AC Transit[]

Other riders take the $4 ($2 Youth/Senior/Disabled) AC Transit Transbay Buses from the Transbay Terminal at 1st and Mission Streets in San Francisco, to the East Bay However, these buses can only fit 2 bikes on their racks, so this should not be considered a reliable way to arrive to cross the bay.

Conflict with Motorists[]

This ride is not without its colorful incidents. The following is a rough excerpt from the Wikipedia Critical Mass main article [1] and describes a "conflict" incident in which a motorist drove into the Berkeley ride:

On May 11, 2007, an incident occurred in Berkeley, California. According to a Bicycle Civil Liberties Union (BCLU) media release, a "motorist with his wife deliberately ran into the side of the monthly Berkeley Critical Mass bicycle demonstration"[2] and caused approximately $3,000 worth of damage to bicycles.[3] The driver, Harlan Head and his wife Marilyn Head of Berkeley, CA, and two hostile witnesses, one of whom had been traveling in a caravan with the Head's, allegedly told police that the bikers 'threw' their bicycles under the vehicle. In viral internet videos on YouTube and elsewhere, one of these witnesses, an unidentified woman wearing a lavender colored fleece jacket, is depicted shoving Ms. Head in the buttocks area as she climbs back into the van, indicating a possible familial or friendship relationship to the Heads. Subsequently, Critical Mass participants pounded on the hood and windows of the car, in an attempt to get Head to stop the van, and the windshield of the vehicle was cracked and fractured.[4]
