Trek recently launched their 'One World, Two Wheels' website as a focus point on their bicycling advocacy, their aim in the US is to increase bicycle trips from 1% to 5% of trips made. Their slogan : Go By Bike.

It's US-Centric, but Trek Australia are involved in bicycling advocacy in Australia, being members and contributors to local advocacy groups. When you buy a Trek, some of your money is going towards making the world a better place, and not just because you'll ride more, but they're helping everyone to ride more.
