If I had more time and more talent I would love to enter this contest. The design on the bag above is the design on one of my favorite t-shirts.

Clearly the challenge is to design something awesome with a bicycle theme. The winning design will be printed on both a t-shirt and a messenger bag which is pretty cool and to add to the cool factor 25% of the proceeds from the winning messenger bag and tee will go towards World Bicycle Relief. Here is what Threadless has to say about them:

Since 2005, World Bicycle Relief has distributed more than 120,000 bicycles. Those bikes have benefited more than 600,000 individuals by shortening travel time to clean water, education, healthcare, markets, and jobs. 25% of the proceeds from the winning messenger bag and tee will go towards the organization to bring more bikes to more communities.

The prizes are awesome too:

• $1000 cash
• $250 in Threadless gift code
• A custom-built Surly/SRAM bike just for you by Iron Cycles. Components include SRAM chain, drivetrain, and bike tape. ($3,000 approx. value)
• One-of-a-kind, handcrafted, ‘Bicycle Charles’ sculpture by Zambian artist, Charles Mwanjeleka
• SRAM hat
• World Bicycle Relief edition CatEye wireless bike computer
• Pedro’s tire lever set
