You can read about them here. They were made by Lincoln Car Works for Sears to sell from catalogs. https://en.wikipedia.org/wiki/Lincoln_Motor_Car_Works
They had to compete against cars from Ford that were much faster, up to 45 mph for the Ford Model T, compared to only 25 mph for this Sears model.
Im glad they specified that it can do all the speeds in between 1 and 25, I was thinking maybe it would instantaneously accelerate from 10 to 15.
