Light one-seater carriage with two or four wheels, named after an English clergyman (8)
I believe the answer is:
stanhope
(Other definitions for stanhope that I've seen before include "old-fashioned conveyance" , "vehicle" , "It may have only two wheels" , "Light horse-drawn carriage; Nineteen across (anag.)" , "carriage that has seat only for one" .)
