"There's no single reason why bicycle commuting has gone into high gear, though spiraling gas prices, concern about greenhouse-gas emissions, and an appreciation of messenger cool are surely contributing to the crowded bike lanes. Philadelphia's nearly flat central street grid is perfect terrain for bicycles. Besides, pedal power is often more reliable than taking SEPTA or driving. No wonder bicycles have become the transportation of choice for low-paid workers, like those who staff the city's restaurant kitchens."
"The problem starts when the bikers stop. There just aren't enough bike racks on Philadelphia's heavily used, narrow sidewalks for everyone. Desperate bikers will lock to anything that won't move, like Rittenhouse Square's elegant wrought-iron fence or the railing around SEPTA's 16th Street concourse entrance. The tangle of metal is not pretty."
"The Nutter administration hopes to improve the situation somewhat in the next few months. It just ordered 1,500 racks and expects to begin installation in November."
