There are probably 2,500,000 bicycle riders in the United States, and it is estimated that a million wheels will be sold during the present year. Take into account 250 bicycle factories, 24 tire makers, and 600 concerns dealing in bicycle sundries, all representing a combined investment of $75,000,000, and the bicycle question seems to gain proportions. Add the number and value of repair-shops, race-tracks, and club-houses, and the aggregate jumps again. Consider the fact that this country contains about 30,000 retail bicycle-dealers and about 60,000 persons employed in the ‘sundry’ factories, and that these numbers are every day growing apace
