Apparently Rob decided, since it was a new city, it would be nice to take the scenic route and bike through the streets. Its not like we haven't seen him ride a bike before (Remember Me) but wouldn't it be interesting to know Robert Pattinson just rode past you on a bike? Hmm.
"Workers at a capital cyclery in Essen Lane confirm that Robert Pattinson, who plays the vampire Edward in the films, visited the store over the weekend and bought a new bike. An employee said Pattinson "wasn't there to be a big celebrity" and that they had received other calls about the visit. "It's getting a bit out of hand", the employee said." - http://http//www.wbrz.com/news/robert-pattinson-buys-bicycle-in-baton-rouge/
He stopped in this past weekend, showing once again he isn't about the hype.
