Cars were the action because they sold for high bucks. By 1910, Daimler would have 900 machine tools on the production floor, with 2000 people at work. Cars had multi-speed gearboxes, clutches, magnetos, overhead valves—everything long before they came to their poor relations: bikes. The car/bike price ratio was 40-to-1, so figure it out: If today’s four-door econobox is $18,000, divide that by 40 and think how many cylinders, cams and valves we’d get for $450. At that price, we’d be lucky if it ran.
