Devices set for biking upright enables to apply an additional effort cyclist to the operator-powered vehicle. The set contains supports with additional pedal levers and a sprocket embraced by the driving chain of the vehicle. This sprocket is connected to the levers by virtue of free wheeling mechanism. The set may also include supporting poles for the upright cyclist. The set can be mounted virtually on any bicycle, so that to improve its operational parameters. A vehicle with devices set can become a day-to-day transportation means and fitness-improving means, since the partners can exchange places during the journey. Different modification tricycles with the devices set mounted on them can be adopted for two or even three partners in addition to the main cyclist. Including the devices set as mentioned above together with a pedal cartridge containing a free wheeling mechanism creates a new type of a motor-less vehicle for biking upright.
