Bicycle transportation is good for a lot of things — it’s healthy, it’s green, it’s quiet, it’s fun, it builds community.

In the Bikenomics series, Elly Blue explores the scope of that impact, from personal finance to local economies to the big picture of the national budget. In the grassroots and on a policy level, the bicycle is emerging as an effective engine of economic recovery.
