The Bicycle Transportation Alliance is a non-profit membership organization working to promote bicycling.

This little beaver grabbed his bike and won't stop riding!

The little fellow rides (and wraps) around the side of this light yellow shirt.

The back features a small version of the BTA logo.

Printed on American Apparel, 100% Cotton T-Shirts.

All proceeds go to benefit the Bicycle Transportation Alliance and their pro-bike work.
