Some people believe cars are the single most dangerous threat to our planet, and that bicycles are our only hope to better living and cleaner air. Eh, yes and no. BUT, did you know that some car companies actually make bicycles?! Your head still in one piece?

We picked 5 of our favorite bikes made by car companies from the past couple of years to share with you. Enjoy. And stop the auto hate!
