Development of velomobile
Adámek, Silvestr ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The bachelor thesis deal with one of a lesser-known means of transport as velomobile certainly is at the moment. This research aims to the development and overall complexity of these modern human-powered vehicles using aerodynamics to its advantage. Due to absence of internal combustion engine, velomobiles reduce negative environmental impacts but also dependence of fossil fuels. Different specifications of velomobiles such as wheels configuration, propulsion system and its usage are being analysed in this study as well as main construction elements or invariably innovated materials. For instance, carbon fibres are one of the modern materials contributing to the strength and lightness of velomobile. Modern approaches goes hand in hand with the development of these modern vehicles, aerodynamics optimalizations of the vehicle body, construction strength or questions regarding electric propulsion to be more specific. Although velomobiles represent an efficient way of transportation, initial costs, weight and size could be impediment to the wider public.

E-bikes
Rynda, Vít ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis deals with the topic of electromobility, specifically the drive tract of electric bicycles or recumbent bicycles. The thesis focuses on the most essential parts of the traction system, which are the battery and the electric motor. It includes an analysis of the different concepts of the mutual arrangement of the power source and the electric motor of currently used electric bicycles. It also includes descriptions and characteristics of batteries, from past to present representatives. It also includes a brief description of the types of electric motors in use. The practical part involves working with software designed for modifying and configuring the control units of electric vehicles with a central electric motor. Several control unit settings are made, where each of them offers customized motor power limits, assistance levels and driving behaviour. The individual settings are tested under the same specific conditions and compared with each other. Finally, a possible ideal solution is proposed in the form of control unit value settings for the examined criteria.

Design of recumbent bike
Sazima, Ondřej ; Lehocký, Peter (referee) ; Zvonek, Miroslav (advisor)
The subjekt of this thesis is design of recumbent bicycle. Recumbent bicycle is designed as tricycle with partially open fairing. Main aim was to design a functional and timeless design using modern technologies. Recumbent tricycle was designed with the fairing and tilting mechanism to easily corner, with innovative solution of turning which makes easier to mount and dismount recumbent tricycle. The work was solved by design, technical and ergonomic side also includes other aspects of the design.

Velomobile Pony 4 Towing Vehicle Design
Hrdina, Petr ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
This bachelor's thesis focuses on presenting alternative means of transportation for individuals and shipments in the context of growing awareness of the impact of transportation on the environment and deteriorating traffic conditions in large cities. The main objective of the thesis is to introduce available designs of cargo bikes and velomobiles, their accessories on the market, and propose a conceptual solution for manufacturing a hitching device for the Pony 4 cargo bike. This hitching device will enable easy and quick increase in the cargo bike's carrying capacity. The thesis also includes the design and production of a prototype trailer cart.
