Famous bike with a rowing movement with a movable seat "Rowbike", commercially available in the United States, consisting of a frame mounted on the rear drive wheel and the front swivel wheel, fixed on the frame rail on which the carriage is installed on the seat to the frame by a hinge attached two shoulders lever, one end of which is fixed arm and the other end is kinematically connected by a chain and sprocket through an overrunning rotation of the drive wheel, and foot rests for mounted on the fork of the front wheel (see www.rowbike.com).

This bike has an awkward running feet and large energy losses, since the movement of the whole bike varies relative to the driver. Famous bike with the movement of rowing with fixed relative to the frame seat "Vogabike", mass-produced in Italy, consisting of a frame with a seat mounted on the rear drive wheel and the front swivel wheel while over the front wheel attached to the frame rail, on which the carriage with two stops for the legs. To the frame by hinge is attached to the swinging wheel, the rotation of which a pull of the trigger is associated with the rotation of the front wheel. The movement of the carriage and swing the steering wheel are connected by a rope with the rotation of the pulley fixed to the frame, rotation of which is associated with the rotation of the rear wheel via chain drive and freewheel (see. www.vogabike.com).

This bike has very high inconvenient location of the stops for the legs over the front wheel and the small diameter front wheels. It is very complicated transmission. Closest to the claimed is the bike with the movement of rowing, consisting of frame made in the form of the guide, installed on the carriage seat and guide for the footrest, and frame mounted on the rear drive wheel and the front swivel wheel, fork and which is rigidly attached to the wheel fixed in bearings of the frame. Emphasis for the legs is connected kinematically chain thrown over the sprocket or cable wound on the block, with the rotation of the drive wheel via a freewheel. This bike is manufactured in Slovenia (see www.sculltrek.sk).

However, this bike has a carriage with foot rests for is too high above the front wheel, which is inconvenient, and because of this forced the front wheel is made of small diameter, which reduces permeability. The aim of the present invention is to improve usability by reducing the level of carriages with the stops is when using the front wheels of large diameter.

This goal is achieved by the fact that the bike with the movement of rowing consists of a frame made in the form of the guide, installed on the carriage seat and guide for a stop for the legs and frame are installed on the rear drive wheel and the front swivel wheel, fork and which is rigidly attached to the wheel fixed in bearings of the frame, and the support for the leg is connected kinematically chain thrown over the sprocket or cable wound on the block, with the rotation of the drive wheel via a freewheel, characterized in that to increase the usability guide stops foot made in the form of left and right swing arms, the lower ends of which are attached to the supports for the feet in the pedals, and the upper ends of which are attached to the shaft mounted on bearings of a bracket attached to the frame, and the shaft is above the steering wheel. And levers cover the front wheel so that the pedals are at the level of the middle part of the wheel, and each pedal or lever is connected by a pull chain or rope. Left and right arms may be rigidly attached to the shaft. Left and right arms can be pivotally attached to the shaft with the possibility of deviation to the side, and to the fork of the front wheel attached plate, resting in the arms when turning the front wheels.
