The cyclemobile is of the three-wheeled type and can be easily constructed in the home workshop with ordinary tools. The main frame is built up of two sidepieces, AA, Fig. 1, each 2 in. thick, 4 in. wide, and 7 ft. long, joined together at the front end with a crosspiece, B. of the same material, 17 in. long. The sides are placed slightly tapering so that the rear ends are 11 in. apart at the point where they are joined together with the blocks and rear-wheel attachments. A crosspiece, C, 13 in. long, is fastened in the center of the frame.

The place for the seat is cut out of each sidepiece, as shown by the notches at D. which are 2 ft. from the rear ends. Two strips of wood, E, 1/2 in. thick, 4 in. wide, and 22 in. long, are fastened with nails to the rear ends of the sides, as shown. The rear wheel is a bicycle wheel, which can be taken from an old bicycle, or a wheel may be purchased cheaply at a bicycle store. It is held in place with two pieces of strap iron, F, shaped similar to the rear forks on a bicycle, and each piece is bolted to a block of wood 3 in. thick, 4 in. wide, and 6 in. long, which is fastened to the sidepiece with the same bolts that hold the strap iron in place. The blocks are located 20 in. from the rear ends of the sidepieces.

The pedal arrangement, Fig. 2, consists of an ordinary bicycle hanger, with cranks and sprocket wheel set into the end of a piece of wood, 2 in. thick. 4 in. wide and 33 in. long, at a point 4 in. from one end. The pieces GG are nailed on across the frame at the front end of the car. to hold the hanger piece in the center between the sidepieces, as shown in Fig. 1. A small pulley, H, is made to run loosely on a shaft fastened between the side-pieces. This is used as an idler to keep the upper part of the chain below the seat.

The front axle is 30 in. long, pivoted as shown at J, Fig. 3, 6 in. from the front end of the main frame. Two small brass plates, KK, are fastened with screws on the under edge of each sidepiece, as shown, to provide a bearing for the axle. The front wheels are taken from a discarded baby carriage and are about 21 in. in diameter.

A good imitation radiator can be made by cutting a board to the dimensions given in Fig. 4. A large-mesh screen is fastened to the rear side to imitate the water cells.

The steering gear L, Fig. 5, is made of a broom handle, one end of which passes through the support M and fits into a hole bored into the lower part of the imitation radiator board. A steering wheel, N, is attached to the upper end of the broom handle. The center part of a rope, O, is given a few turns around the broom handle, and the ends are passed through the openings in screweyes, PP, turned into the inner surfaces of the sidepieces AA, and tied to the front axle.

The seat is constructed of 1/2-in. lumber and is built in the notches cut in the main frame shown at D, Fig. 1. The body frame is made of lath, or other thin strips of wood, that can be bent in the shape of the radiator and nailed to the sidepieces, as shown in Fig. 6. These are braced at the top with a longitudinal strip. The frame is then covered with canvas and painted as desired.
