The articulated connection of the steering wheel (12) with the front fork (8) is made by means of at least one cardan joint (11), where on the circumference of the wheels (10) in the zone of tire contact with the ground there is a cycling slick protruding visibly in front of the tire front and below it is an off-road tread. From the Polish patent application PL-394406, a bicycle with a front-wheel drive is known, which, after turning the steering wheel by approx. 110 ° in relation to the front wheel frame, significantly reduces its dimensions and which can be easily converted into a tandem. The bicycle has a support frame composed of a frame (1) of the front wheel (15) and a frame (2) of the rear wheel (16), to which a saddle (19) with a backrest (14) is attached. Both frames are connected with each other by the articulation (3) and by the rope crossed transmission (10, 11, 12). In this joint, the pivot (3), being the common part of both frames, cuts the road surface at point (C) at an angle of 69 ° ± 3 °, 20 ± 4 cm behind the contact point of the front wheel with the road. The used drive system (18) is preferably located in the axis of the driven wheel and consists of a crank system (17), an epicyclic satellite gear and a one-way clutch. The steering wheel (7) is rotatably mounted in the switch (4) of the front wheel frame (1) and is fixedly connected through the switch shaft to the large wheel (10) of the rope cross transmission. The steering knuckle (4) of the frame (1) has two bearings (8, 9), the bearing (8) at the steering wheel (7) being a low friction bearing, while the bearing (9) at the gear wheel (10), is a high-torque radial plain bearing. The gear ratio of the rope cross transmission (10, 11, 12) is 1.4 ± 0.1: 1. The small wheel (11) of this transmission is fixed to the frame (2) of the rear wheel (16), in the pivot axis (3) connecting both frames (1, 2), and the large gear (10) is fixedly connected by the steering shaft (4) with the steering wheel (7) and rotates along the axis (6) of the steering knuckle (4) of the support frame (1). The cable (11), connecting the gear wheels (10, 12), crosses between the large wheel (10) and two relieving rollers (13) located next to the wheel (10). A bicycle is known from the Polish patent description PL-172053. The bicycle is shifted between a standard bicycle configuration for normal riding and an exercise configuration in which the bicycle is propelled forward alternately by saddle movements and pedal movements, with the movement of the saddle transferring the weight of the rider to the seat (5) which moves downwards to propel the bicycle. crankshaft (6) and by shifting the two in-line pedals (4b) upwards, the movement of the pedals ensures that both pedals (4b) are pressed down to move the saddle back up. In the practice configuration, it has a design whereby when the pedals (4b) are at the lower turning point, the weight acting on the saddle (5) is applied to the crank at an angle to the vertical to keep the drive forward and when the saddle is at the lower turning point. the pedals (4b) are just in front of the upper turning point so as to keep the drive forward. In the practice setup, the pedals may be limited to only turning in one direction with a ratchet. The Polish patent specification PL-182850 describes a bicycle with an electric assist drive. A bicycle with an electric assist drive is characterized by the fact that the rear wheel with a chain drive has a chain wheel or a single or multi-row freewheel (1) attached to the hub (2) on the left side, which is a mirror image of the right freewheel, while the gear or freewheel (1) it is driven by a DC electric motor (3) with a reduction gear placed above it by a chain powered by a battery (7).

The invention relates to the construction of a tricycle, used in particular for the transport of luggage and goods by elderly and disabled people. A tricycle has rear wheels (12, 13) built in the casing (3) of a frame connecting them (2) connected to the frame (1), each of which is rotatably mounted on its axis (21, 22) at two support points. The drive is transmitted via endless chains (10, 11) from the crank mechanism (5) to at least one rear wheel (12) through chain gears (7, 8) mounted on a shaft (6) located in the body (4) attached to the frame frame ( 2) and casing (3), and through a chain transmission (9) built on the axis of the rear wheel (12). The frame (2) is detachably attached to the frame (1) of the bicycle, and the body (4) is detachably attached to the frame (2) and the casing (3). From the Polish patent specification PL-191194, a bicycle is known, characterized in that it has on the frame (1), between the rack (6) of the rear road wheel (5) and the gear (12), drive, two coaxial center racks ( 8, 9) and two chains, a rear chain (7) and a front chain (11), from which the rear chain (7) transmits the drive from one middle sprocket (8) to the sprocket (6) of the road wheel (5), and the front chain (11) transmits its power from the drive pinion (12) to the second middle sprocket (9). From the Polish patent description PL-212704 a bicycle is known in which the height of the seat position changes even while riding it. The seat (8) is mounted on the piston rod (7), guided in the cylindrical part of the support frame (5), which additionally serves as a hydraulic-pneumatic device.
