The reason you dont see complete bikes in edits is because 99% of the time you dont see a beginner edit & most of the time completes are for people just starting out. Im no pro but i like to have a bike that i have chosen every part myself, i like to put the bike together myself & depending on where you buy it from i can almost guarantee i could put it together better than the majority of shops. As i mentioned, as you progress with riding you will begin swapping parts out for aftermarket parts & eventually you will end up with a full custom which is what the majority of riders have done.
