I don't really know anything about Electra bikes but looking at the specs on the one you mention indicate a pretty low-grade machine. "Hi-ten" steel frame, coaster brake....

That Shimano Nexus 3-speed is just fine until you need to fix a flat... Have fun. Price is not listed on the site... It's going to be a heavy, slow cruiser.... Probably comfortable as long as you're on level ground.
The various Trek hybrid (and "comfort" or "fitness" ) bikes are well-proven, reliable, have standard components.....
