True dat. Depending on the frame, though, you might have an issue with rear spacing/spreading the frame. I think some of those Electras are aluminum, too.... Spreading an aluminum frame has been done, but I can't recommend it.

I recently bought a SA S2 kickback hub... the kind without a coaster brake.... that thing is spaced at 110mm, which is/was the cruiser standard. I'll be running mine with a u-brake. The coaster kickbacks are spaced at 116mm or more, depending on the brand/version.... (I have a 70s-era Sachs Torpedo Duomatic which is spaced 112mm....)
