Folding bicycles, the nerdy mode of self-propelled transportation preferred by anyone who has to go more then 4 blocks from home to train or train to office, will now be allowed on all Muni buses, trains and streetcars Bay City News reports. The portable pocket bicycles will be allowed on the bus itself provided they don't block aisles or wheelchair spots. This is great news for anyone who hates actually riding the bicycle they purchased, but does not bode well for Muni drivers who already get testy at the sight of a stroller.
