Doseděl, Jan ; Ptáček, Petr (referee) ; Semela, Marek (advisor)
Master thesis titled “Analysis of selected manoeuvres of bicyclists” in the first part deals with the history of bicycles, construction, division of bicycles and introduces–traffic accidents of cyclists and national legislation. Practical measurements with bicyclists is in the second part of this thesis. Cyclists performed deceleration on three surfaces, acceleration and a manoeuver, in which cyclist looked behind himself before changing the direction. The evaluation of all measurements and comparison with other similar works has been made in the last chapters.

Analysis of Selected Manoeuvres of Bicyclists
Špačková, Kateřina ; Belák, Michal (referee) ; Semela, Marek (advisor)
This diploma thesis Analysis of selected manoeuvres of bicyclists deals with the history and development of the bicycles, further their division of, construction, analysis accident and national legislation in the theoretical part. The practical part of the master thesis is devoted to the measurements of the bicycles. Specifically, it is about acceleration, deceleration, transverse movement, ride in the curve and looking back before changing the direction. For measuring are selected different type of bikes with different construction. The results of individual measurements are evaluated in the end of the diploma thesis.

Composite Bicycle Frame Design
Bartoška, Vojtěch ; Řehák, Kamil (referee) ; Janoušek, Michal (advisor)
This work aims to the design of a carbon fiber bicycle frame with production technology suitable for piece production. The work summarizes the methods of production of composite frames and important parameters that must be respected when designing the frame. A Gravel frame was chosen for the design. The frame was designed for production using stainless steel printed lugs with glued composite tubes. The proposed solution was strength tested. The work also contains a design of a production jig for the construction of bicycle frames.

Selected Measurements of the Motion of Bicycles - Braking and Travelling Around Bends
Prčík, Stanislav ; Krejsa, Ivan (referee) ; Semela, Marek (advisor)
Diploma thesis Selected measurements of the motion of bicycles – braking and ridein the curve analyses problematic manoeuvres of bicycle riders according to the most typical accidents including bikes. There will be given statistics of bikers´ participation on accident amount that happened within last few years. The measurements of bicycles moving around bands of specific radiuses as a situation of most bicycle accidents will be described in the next part of this thesis. There will be also specified the values of average bicycle speeds when driving in curves with various radiuses according to types of bicycles, sex and experiences of the riders and will be an output of this thesis. Further on there will be measurements of braking in the direct line on various surfaces with different types of bikes and different brakes used.

Design of bulk cold forming technology for bicycle part
Kubíček, Lubomír ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The diploma thesis is dealt with a project of a new manufacture method of a bicycle´s part. The part is a brake drum, which is the necessary part of a free-running charge. In an intro-duction of the diploma thesis is described a nowdays manufacture technology and its deficiencies. According to the nowdays manufacture technology was designed a new one, which is based on a cold volumetric shanking. The shanked hemihedron is consequently shaped according to the current technology. After the operation of cold shaping an instrument is projected. The project of the shaping technology is filled up by the calculation of the essential parameters, including an arrangement of the instrument and the process. An economical evaluation of the new process of the brake drum is stated and its advantages and disadvantaged were selected.
