Bike shop in Warren celebrates over 100 years

August F. Thumm's mother, discouraged her son was working as a plumber for less than three cents an hour, recommended he consider a different line of work - maybe something with mechanical devices because of his fondness for tinkering and skill with his hands.

Augie Thumm, August's grandson, said his granddad always had an affinity for motorcycles and bicycles, and taking his mother's advice, August F. Thumm went into business with his brother, Karl, selling Harley-Davidson motorcycles, bicycles and tires.
