Pitcher and Bartlett

of 119a Holland Park Avenue, London
PB was a motorcycle produced in 1903.
Late that year the firm built a motor tandem with its 2.75hp Chapelle engine fitted between the two riders. It had crossed flat belt rear-wheel drive and the frame was designed for a gentleman at the front and a lady at the rear. The crossed belt arrangement made it very short lived.
