Strange story: Bicycles don't need chains!

At the exhibition in Padova, Italy, the bicycle design team of Csepel Schwinn ZRT - Hungary has just released a new bicycle model with absolutely no leash chain.

Instead of the leash, the manufacturers have designed this Stringbike bike model, a system of symmetrical wires and very special pulleys. According to designers, this system makes the bike more efficient, makes the move more comfortable, more maneuverable and especially suitable when running on winding streets.

The new control system consists of a system of wires and pulleys mounted on one side of the vehicle. The rotation of the axle pedals controls the movement of the vehicle forward and backward.

When moving forward, the pedal works to pull the control cord wrapped around a drum on the rear wheel, forcing this wheel to rotate around the shaft. Pedal on each side of the chassis rotating so that one turn in this direction the other turns in the opposite direction.

Vehicle speed adjustment system with 19 " gear " position and transmission rate can be changed easily by pressing the switch button on the right handle. The new system consists of eccentric discs attached to bicycles to spin the discs on both sides of the chassis.

The shapes of these discs can be made differently depending on the purpose such as traveling or racing on different terrains. The control wires make special materials, with high stability for a long time, able to resist mud, water, sand, dirt, and moisture.

The outstanding advantages of this bicycle model are:

1. Because the new design does not have a chain, there is no lubricant that makes the clothes dirty.

2. The rear wheel can be removed from the frame without any difficulty. Removing the rear wheel takes only a few seconds. This allows the user to easily collapse the bike when it is needed to carry it on the car during long-distance trips, or when it is necessary to store the vehicle in tight spaces.

3. The rope can be mounted in different positions on the two sides of the bike, which means it can be adjusted appropriately if one of the driver's legs is weaker than the other leg. This is not possible with conventional bicycles.

4. The lifespan of parts in the vehicle will be longer than that of a conventional bike because in the traditional vehicle the chain is easily worn.

5. Some parts may be reduced to lighter vehicles.

6. The almost constant forms of traditional bicycles can be boring for users in the past few decades. This new bike form can also become the focus of attention and become fashionable.
