"If I could not get another bicycle I would not give mine for its weight in solid gold. For fifteen years I lost from three to eight days every month with stubborn sick headache. Since I have been riding the bicycle I have lost only two days from that cause, and I haven't spent a dollar for a doctor."
--Rev. George F. Pentecost
