On "Gossip Girl," the characters are used to be shuttled around New York in town cars.
But in real life, star Penn Badgley is a biker dude!
The handsome actor was spotted biking around Manhattan and even rolled up his shirt to show off his biceps. Biking is a great alternative, eco-friendly transportation alternative that even celebrities are embracing -- and a great cardio workout!
Check out Penn getting his bike on in the photo gallery below!
