Analysis of the Speed of Cyclists Aged from 10 to 15 Years
Valentová, Hana ; Semela, Marek (referee) ; Bradáč, Albert (advisor)
The thesis is concerned with an analysis of speed of bicyclists in age between 10 and 15 years. The thesis examines differences in construction of children's bikes, describes relationship between a child and a bicycle, messures size of children's bikes and characterizes the procedure during an analysis of bike accidents. Internal parts of the thesis are statistical data from accident frequency and summarizing of actual state of understanding of following problems in this age category. The main purpose of this thesis is to make an analysis of speed for individual age categories and make an evaluation of results. This measurement will be completed by a measure of achievable brake deceleration of riders in age between 10 and 15 years. The purpose of this final thesis is an expansion of data for a forensic expertise in area of Traffic.

To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Hudečková, Kristína ; Růžička, Tomáš (referee) ; Ponešová, Barbora (advisor)
The terminal represents joining two things – an internal and an external – a city and a surroundings. The intetion of my bachelor thesis is to connect fluently a main hiking trail from a center of city with a bus service and train transport. To make this connection as natural as possible, the proposal of terminal is based on a mass concentration in a point of joint and gradual diffusion towards the the city and the surroundings. The terminal is designed as a longitudinal structure with a one communication in the middle of the layout. The space of terminal is defined by twenty steel frames arranged one behind the other in the direction of the axis of connection between train track and hiking trail from the center of the city. The steel frame becomes the dominant element of the terminal. Different closing of sections between particular frames creates spaces of different characters and a different rate of permeability.

Theoretical Concept of Power Drivetrain in Human Powered Vehicle
Frank, Boris ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Thesis is aimed on regeneration braking systems in human powered vehicle, which uses a flywheel as an energy storage medium. In the beginning is research about design and usage of flywheel energy storage systems in vehicles. Research about possibilities of continuously automatic shifting in HPV is also accomplished. Practical part deals with design of flywheel and FEM analyses of it. Also take into account practical aspects and problems of designing kinetic energy recovery system in bicycle. In energy balance thesis appreciate contribution of practical application of this system.

Selected Measurements of the Motion of Bicycles - Travelling Around Bends, Transverse Movement
Křenek, Jan ; Krejsa, Ivan (referee) ; Semela, Marek (advisor)
Diploma work named Selected measurements of motion of bicycles starts with history and development of bicycle. There are components of bicycles described and analysis accidents with cyclist. There is a goal organise and realize measurement of ride in the curve and tranverse movement. The outputs are going to be use by experts in sphere of transport accident analysis. There will be exists data analysis then starts maeasurement. After then compile sources from measurement – break testing, ride in the curve testing and tranverse movement on the most frequently road surfaces with part of enaugh cyclist and bycicles. The end of work is already existing data with hold of measurement data comparison.

Design of city-electric bicycle
Sojka, Vojtěch ; Zdařil, Zdeněk (referee) ; Rubínová, Dana (advisor)
The subject of this diploma thesis is design of electric assisted city bicycle – so called pedelec. The aim was to propose a design that will meet both the requirements of clientwork and the criteria of timeless design with modern materials and technology. The result is a design which, compared to commercially available electric bikes, stands out with much better weight distribution and user comfort.The thesis is soluted by design,technical, ergonomic, psychological and economic terms. Diploma thesis has 84 pages.

Multipurpose bicycle alarm
Albert, Matej ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This diploma project is about designing a concept of an anti-theft tracking device for a bicycle. The device is equipped with a GNSS module for tracking of current location, GSM module for sending the location data in case of a theft and a BT module for user settings via mobile phone. The bike theft detection is detected by an accelerometer. The final goal of this project is a concept of such a device for evaluation and improvement purposes.

Modification of the crank store on a bicycle
Kupčák, Radim ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
In its first half this thesis describes most common materials used in the bicycle industry as well as various types and standards of bottom brackets and mentions their pros and cons. Starting with the oldest cotter pin type all the way to the most modern press fit bottom brackets. The major objective of the second part of this thesis is to design a crankset based on the research in the first half. One of the most important aspects of the design was to choose a suitable type of bottom bracket for non-competetive riding. Structural analysis using finite element method was done and the design was altered accordingly. In the end the process of manufacture was described.
