Eric Greenfield's Smooth Operator Knucklehead Chopper

Eric Greenfield might be one of the most enthusiastic chopper builders I’ve ever met, hands down. Enthusiasm emitted in a way that is contagious, in a good way, and with the know-how and creativity to back up that enthusiasm, his bikes are something to stop and take notice of. His last build certainly got my attention when I spotted this unassuming, humble, and friendly guy roll into a party and casually park his shovelhead-powered work of art. I immediately went over to have a look and was more than impressed. After doing some digging I found photos of a longbike he had built which immediately won my heart. Needless to say that when Eric reached out about photographing his new knucklehead chopper, appropriately named Smooth Operator, I certainly wasn’t going to say no.

Smooth Operator is an S&S-powered knucklehead delicately wrapped in a decorative purple and chrome display of artisanal craftsmanship. The details are endless. The amount of thought put into every nook and cranny is apparent. The creativity is a direct reflection of its maker. I implore you to pause for a few moments, take a look at the photos and follow Eric to watch his future builds. I have no doubt that there will be many more coming down the pipeline. Hats off to you, Eric! - Charlie
