The invention relates to off-road bikes and can be used in racing over rough terrain.

Famous all-wheel drive Bicycle, comprising a frame with a seat, the rear drive wheels and front drive wheel with the fork and carriage coaxially with pedals front wheel and is connected through a system of chain drives the rear wheel (see the patent of Russia №2379211).

However, this bike complicated transmission, you cannot stand up while riding on the pedals to absorb the bumps, and a very short base, fraught with the toss of a cyclist through the steering wheel.

Closest to the claimed is all-wheel drive Bicycle "Kalmius". consisting of a frame with a seat, the rear drive wheels and front swivel wheel, the rotation of which is associated with the wheel, the carriage rods and pedals with drive pulleys associated with the rotation of the pulley rear wheels and with the rotation of the front pulley wheel closed connections such as belts and pulleys on the sides of both branches of the front strap. (.etracab.ru a forum. Theme bike "Kalmius").

However, this bike is almost unmanageable because of the absence of stabilization of the front wheel, front seat belt does not rotate the front wheel to one side. The angle of rotation of the front wheel is small, due to the possibility of a small side it is Shiba. Pedaling gives the reaction of the wheel and the hands, which is unacceptable.

The aim of the present invention is to increase the angle of rotation of the front wheel.

This goal is achieved by the fact that all-wheel drive Bicycle, comprising a frame with a seat, the rear drive wheels and front swivel wheel, the rotation of which is associated with the wheel, the carriage rods and pedals with drive pulleys associated with the rotation of the pulley rear wheels and with the rotation of the front pulley wheel closed connections, such as belts and pulleys on the sides of both branches of the front strap, characterized in that the inclined axis of rotation of the fork of the front wheel crosses, when viewed from the side on the bike, the intersection of the tires of the front wheels with the lower branch of the timing belt, and both branches of the front timing belt twisted in its middle part rollers quarter turn while the front wheel tilted to one side so that the pulley rises in the longitudinal plane of rotation of the plug and passing through the contact patch of the front wheel with the road.

The purpose of the depreciation of the front wheel steering is performed with removal of the forward and the shaft of the fork associated with the stem attached to the articulated fork, this fork through the hinge, damper and hinge connected with the stem.

The invention is illustrated in the drawing.

All-wheel drive bike consists of a frame 1, a seat 2, the drive of the rear wheels 3 and swivel front wheels 4 tire 5. The plug 6 of the front wheel 4 by a hinge 7 is attached to the shaft 8, mounted on bearings of the frame 1. To the upper part of the shaft 8 is attached takeaway 9, is attached to the wheel 10. The plug 6 by the hinge 28, the shock absorber 11 and the hinge 12 is connected with the removal of 9.

On the frame 1 is fixed to the carriage 13 with the connecting rods 14 and 15 and the pedals 16 and 17. The carriage 13 is provided with a driven pulley 18, which toothed belt 19 connected to a pulley 20 of the rear wheel 3. The pulley 20 is connected with the rear wheel 3 by the ratchet.

The carriage 13 is provided with a driven pulley 21, which is located on the axis of symmetry of the Bicycle.

The pulley 21 is connected toothed belt 22 to a pulley 23 of the front wheel 4. The pulley 23 is connected with the front wheel 4 ratchet. The carriage can be multi-speed and can be used German serial dvenadtsatiletny carriage. The upper branch of the belt 22 is twisted in the middle part of the quarter turn rollers 24 and 25 attached to the frame 1. The roller 24 in contact with the teeth of the belt 22, made in the form of a gear tooth.

The lower branch of the belt 22 is twisted in the middle part of the quarter turn rollers 26 and 27 attached to the frame 1. The roller 26 in contact with the teeth of the belt 22, made in the form of a gear with zu is lame.

The shaft 8 of the plug 6 are filled with the tilt angle α equal to 50-55 degrees. The axis of the shaft 8, if you look at the bike from the side, crosses the place of restraint for the lower belt 22 with the lid 5 of the front wheel 4.

The front wheel 4 is tilted to one side at an angle β so that the pulley 23 rises in the longitudinal plane of rotation of the plug 6 through the contact patch of the front wheel with the road, or approximately in the plane of symmetry of the Bicycle, so that the pulley 21 and the pulley 23 is approximately in the same plane.

The bike works as follows.

The cyclist pedals 16 and 17 and through the belts 19 and 22 causes the rotation of the drive wheels 3 and 4. Turns the Bicycle wheel 10.

Stated the bike has enough steering angle. The front wheel is stabilized during the drive, so the bike can be used to compete in cross-country.
