It's correct that Aragorn was the only strider of the North ever mentioned. But from this we can interpret that striders (at least one) did exist in Middle-earth. And if one, then why not others? Aragorn is given prominence in the story because he's related to the ruling house. But Eriador has many other inhabitants not featured in the stories. There is no reason to assume Aragorn would be the only man ever to walk that fast.

The Striders should be rare units who do not spawn generally alongside other warriors, but rather only appear rarely in certain places. It's a way to make Rangers of the North as a faction more interesting and distinct from others, and while not explicitly supported by the canon, it does not conflict with it.
