The staple of their business was, however, the letting of bicycles on hire. It was a singular trade, obeying no known commercial or economic principles--indeed, no principles. There was a stock of ladies' and gentlemen's bicycles in a state of disrepair that passes description, and these, the hiring stock, were let to unexacting and reckless people, inexpert in the things of this world, at a nominal rate of one shilling for the first hour and sixpence per hour afterwards. But really there were no fixed prices, and insistent boys could get bicycles and the thrill of danger for an hour for so low a sum as threepence, provided they could convince Grubb that that was all they had. The saddle and handle-bar were then sketchily adjusted by Grubb, a deposit exacted, except in the case of familiar boys, the machine lubricated, and the adventurer started upon his career. Usually he or she came back, but at times, when the accident was serious, Bert or Grubb had to go out and fetch the machine home. Hire was always charged up to the hour of return to the shop and deducted from the deposit. It was rare that a bicycle started out from their hands in a state of pedantic efficiency. Romantic possibilities of accident lurked in the worn thread of the screw that adjusted the saddle, in the precarious pedals, in the loose-knit chain, in the handle-bars, above all in the brakes and tyres. Tappings and clankings and strange rhythmic creakings awoke as the intrepid hirer pedalled out into the country. Then perhaps the bell would jam or a brake fail to act on a hill; or the seat-pillar would get loose, and the saddle drop three or four inches with a disconcerting bump; or the loose and rattling chain would jump the cogs of the chain-wheel as the machine ran downhill, and so bring the mechanism to an abrupt and disastrous stop without at the same time arresting the forward momentum of the rider; or a tyre would bang, or sigh quietly, and give up the struggle for efficiency. When the hirer returned, a heated pedestrian, Grubb would ignore all verbal complaints, and examine the machine gravely. “This ain't 'ad fair usage,” he used to begin. He became a mild embodiment of the spirit of reason. “You can't expect a bicycle to take you up in its arms and carry you,” he used to say. “You got to show intelligence. After all--it's machinery.”
