Most people who ride bicycles for pleasure do not ride until the warm weather of spring and summery arrives  Yet it is probably more effective to advertise bicycles earlier in the year  Most bicycles are purchased in the spring, but once shoppers are ready to shop for a bicycle, they usually have already decided which brand and model of bicycle they will purchase
By then it is generally too late to induce them to change their minds
bicycle advertisements are probably more effective if they appear before the arrival of warm spring weather
