It was small and light, built to carry as many as four or five people though I can't imagine how well it would have gone with even four skinny people on it. With just the driver it could carry you along at about 10-15 miles per hour all day without any excessive strain. In a pinch it could do 25 or maybe 30. The top speed was limited by the very low gearing, aimed at pulling it out of ruts and muddy roads. Since there aren't many rutted muddy roads left in New England I fiddled with the gearing and the compression and got a car that could probably do 50. That was a real mistake. The chassis and steering weren't up to the speed and the loss of the very low range made it difficult to climb a steep hill with two people on. But, in its original configuration it must have been a revelation to a horse-centered traveling public with a far different notion of "speed" than we share. It was an inexpensive car too, though extremely well made. One cylinder Cadillacs were so successful that they remained in production until around 1908, long after most other one-lung automobiles were considered wildly obsolete.
Interestingly, one-cylinder cars retained their popularity in Europe far longer and sporty versions were being made and raced right up to WWI. Walter Owen Bentley developed the first aluminum piston for a French one-lunger that he and his brother held an English franchise for and had several racing records to their credit.

I had no idea there'd ever been one cylinder automobile engines. That's really surprising.
It's also very interesting to note that at one time Cadillac's must have been built for rural road use. Maybe all cars were. It's not how we think of them now, but that must have been a necessity. While out over the lunch hour, I passed by a Model A that someone has parked out on the street, and they certainly exhibit quite a bit of clearance.
