The Ukulele by Bicycle Tour is a project of ukulele songwriter Aaron Lee, who rides his bicycle between concerts to promotes community building, local action and sustainability. Each concert benefits an organization that is doing work in their local community. In this way, the concert provides a positive community experience, in addition to raising awareness for the organization. In a global sense, the tour promotes the causes of living simply and sustainably (through the limits and freedoms of touring by bicycle), acting locally (through working with local organizations), and the energy of community (events are a celebration of community through a shared musical experience). In the fall of 2010, Lee rode over 2000 miles and performed over 40 concerts between Portland, ME and Americus, GA. The spring 2011 edition of the tour featured 17 concerts between Spartanburg, SC and Baltimore, MD. The summer tour took him from Baltimore to Milwaukee, WI. The Ukulele by Bicycle Tour is currently on hiatus, but may return at some point in the future.

In February of 2010, Lee released The Ukulele Project, a 14 song record in which all of the songs creatively and intentionally feature the word ukulele. Lee has performed all over the northeastern United States both as a solo act, as a duo with Tucker Louisos-Daniels and with his ukulele, piano, and upright bass trio.
