Some fanboy (hopefully a cycling fanboy… I mean, Josh is cool and all, but really dude) captured this photo of Transformers 3 star Josh Duhamel Du-hamming it up on an e-bike during filming. Thanks to Jason of Jinji Cycles for the tip…c’mon Jason, we know that’s your arm holding the phone cam.

Not shown: Relatively unknown Autobot Eebyke transforms and poses with Duhamel, but Paramount Pictures said those photos violated copyright and made Jason delete those images from his camera.

Some spy footage of downtown filming in Chicago after the break…

Optimus Prime avoiding some explosions.

Autobots rolling through town.
