Reminds me of my Kona Humu Humu! Love the modern bikes that look like old cruisers. One of my favorites was the Merlin Newsboy, and Electra did a similar frame this past year with 29" wheels and 3pc BMX cranks that looked sweet!
That SRAM 3 speed won't live long offroad; the tires won't offer very much traction, depending on the trails you ride. The frame itself is a big questionmark, but everything else looks like it could handle the trails.
