A person who rides a bicycle; an alternative (but less common) term for cyclist or bicyclist.
From bicycle + -er (agent suffix meaning 'one who does'). Less standard than 'cyclist' or 'bicyclist,' but follows normal English word-formation patterns.
While 'bicycler' is grammatically correct, most English speakers say 'cyclist' or 'bicyclist' instead—this is a great example of how English sometimes has multiple correct forms, but custom and habit make some way more common than others.
