And if you should just happen to rent a bike at Recycled Cycles (on the Burke-Gilman trail) you could ride it east on the trail to Counterbalance Bicycles http://www.counterbalancebicycles.com/ and then west on the trail to Free Range and CBS.

You could also ride on the B-G to the Ballard locks and the fish ladders along the ship canal and Lake Union, and in the other direction to Matthews Beach on Lake Washington. No maps required, just stay on the trail.
