Choppers I believed started to appear after the second world war and into the 50s, 60s, and onwards from then. These photos, one from 1910 would suggest that bikers have been customising and personalising their rides from at least as early as that. They have the rigid arse end like many of the modern choppers seem to favour. The modern Chopper might be a little easier to ride, especially when you look at the steering geometry of the 2 in the photos. They had obviously never heard of (trail) back in the day.
