Well, no you don't because this is all coming from an American perspective.

In Europe, trekking is the same as touring. The bikes are set up usually with flat bars, but they may be equipped with 700C wheels or 26". However, in reality, when touring or trekking, the Europeans such as Germans and Dutch will use their normal step-through bikes, their MTBs or (rarely) drop-bar bikes. For us at the moment, we are somewhat out of the norm with drop-bar touring-specific bikes.

The trekking notion outside Europe is based more on the concept of "trekking" by foot through the Himalayas, and when the bicycle tourists followed there, it seemed natural to describe themselves as bicycle trekkers. Hence, someone doing a bike trip through remote areas now is considered more a trekking cyclist (such as our own azesty is with his China to Europe ride) than a touring cyclist (like us who are riding the Rhine Route, but still would be called trekking cyclists by Europeans because of the scope of our trip).
