Single cylinder engines enduro category
Svoboda, Tomáš ; Beran, Martin (referee) ; Vančura, Jan (advisor)
Bachelor thesis deals with the description of typical enduro motorcycle engine and describes its main parts. Next volume concern about chosen types of enduro motorcycles and its en-gines. Achievement of every single engine is shown in dynamometric diagrams. Maintenance schedule which is affected by given achievements is shown in tables. The engines of enduro motorcycles have been partly compared with motocross motorcycle engines

Single-Cylinder Two-Stroke Engine for Enduro Motorcycle
Koten, Stanislav ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This thesis deals with the construction of two-stroke motorcycle engine. Specifically, the racing engine for the Enduro class with a displacement of 250 cm3, adapted to be mounted in a chassis with extremely long swingarm according to patent of Frantisek Krnavek. The introduction briefly describes the E2 class rules and discussed design powertrain solutions of this class. Following design and calculation of required motor parameters. Further attention is devoted to detailed calculation of main bearings lifespan. The next section describes in detail the construction of the crank mechanism, cylinder head, exhaust pipe, power valve and reed valve. Conclusion deals with location of other engine parts.

Design of mountain-bike crossbar and its FEM analysis
Jelínek, Martin ; Maňas, Pavel (referee) ; Vrbka, Martin (advisor)
The aim of this diploma thesis is the part of evolution of the new bicycle frame for mountain biking, category enduro. The first part of this thesis is focused on creating dimensional modified model of the bike frame in CAD system SolidWorks. Subsequently this frame will be detailed by FEM analysis in software ANSYS Workbench and determine boundary conditions for this analysis. The final part is about visualization of the new bike frame.

Origin and evolution of modern mountainbike disciplines
Dytrych, Lukáš ; Waic, Marek (advisor) ; Valjent, Zdeněk (referee)
Title: Origin and evolution of modern mountainbike disciplines Objectives: The aim of this thesis is to compile of history of modern mountainbike disciplines. Next aim is to describe of this disciplines' beginnings in their birthplace in Canada and California. The development of freestyle and freeride and evolution of bike issues trends was delineated too. Some consideration was put to evolution of bike obstacles and to evolution of bike community as such. The next regard was put to pioneers of modern disciplines of this sport, especially to freeride and downhill. Trends in endure issues was said too. Methods: The main information from MTB region and its modern disciplines was processed bz direct historical method and methods of induction and deduction. Research through the retrospective, quantitative and comparison methods was used marginally. Results: The results of this thesis will help to understand where the MTB phenomena is being taken nowadays and will help to understand of influence of extreme MTB disciplines on its community in the local regions and in the world. Keywords: mountainbiking, mountain cycle, history, origin, evolution, downhill, freeride, enduro
