As a still somewhat new Boulder resident, I agree with this. I lived here for a year as a freshman and only saw the city by bus. I came back recently owning a car, and saw more of the town, but it was a bit difficult to get around in all the traffic.

Then I got a bike, and the valley opened up to me. I practically had to relearn my way around using the extensive network of bike lanes and bike paths, but I feel a lot more freedom of movement. I was worried about safety at first, but now I am more comfortable riding than driving.

I know I'm spoiled by this city though. The ride from South Boulder to the shopping district can take you along a gorgeous paved path following a stream under a canopy of trees between suburb neighborhoods. I never feel a need for a helmet.

Downtown boulder has a bike sharing program, but I don't know how much use it gets since practically the whole town rides.
