Horizontal bicycles can be classified as means of transport powered by one's own muscles that are in the lead as regards low aerodynamic drag, riding comfort and safety. This kind of construction is influenced by load that in the case of inadequately engineered bicycle frame may lead to the construction damage. To prevent this, strength and stiffness analyses are conducted whose boundary conditions correspond with these during real exploitation. Various extrusion profiles of the bicycle frame are connected with the use of welding technique which additionally makes us conduct analysis strength of welded joints. These kinds of calculations are carried out with the use of the software basing on the finite element method making it possible to gain stress and deformation values for complex cases of frame load and whose results cannot be obtained in an analytical way. The frame of the horizontal bicycle was put to analysis in the three different load variants. We achieved maximum deformation, stress in the critical points and in the welding joints of the frame, which then were compared to the allowable values. The correct verification of the received values contributed to determining joints vulnerable to damaging and modifying the frame construction to minimalize the possibility of its destruction.
