“…A special method actually designed for the slip risk of pedestrians is the "slope method" [16], which will in this project be used to assess the slip risk for cyclists (see further). Brake tests and turning tests with bicycles were found in several studies, more particular to test the influence of winter/icy conditions ( [17], [18]).…”

Recently the need for more and better cycling infrastructure is soaring. The diversity of the means of transport other than ordinary bikes is increasing rapidly. Consequently, the users’ expectations change. In their endeavor to deliver, road authorities managing cycle paths will benefit from new condition assessment and efficient asset management. In the two-year project “Surface Characteristics of Bicycle Lanes” (SuChar-BiLan), started on 1 November 2022, the Belgian Road Research Centre (BRRC) collects knowledge, information and practical experiences about measurement techniques and management allowing the assessment of the condition of bicycle infrastructure: evenness, skid resistance, texture and rolling resistance. The aim of the project is to help with developing European standards and with expanding the use of such techniques – to a better quality of the cycling experience. This contribution presents results of a literature review, mentions the development of surveys addressed to different stakeholders (users, road authorities, technology providers), describes how technology and service providers, and research organisations will be invited to demonstrate their solutions on bicycle lanes in Belgium, hints on future design by BRRC of laboratory test methods for skid and rolling resistance, and explains the importance of the expected outcomes and of the aimed development of European standards.

“…The used of bicycle is increasing along with the efforts to reduce air pollution and the used of fossil fuels. Bicycles are also a healthy alternative hobby and have a positive correlation between human activities and health [1]. The simulation of T and I profile bicycle frames have been analyzed, and it could be manufactured by casting process [2].…”

The bicycle frame produced through the metal casting process by recycling aluminum alloys can be an environmentally friendly alternative solution. Mold types and gating systems used generally affects the quality of the casting product. In this experiment, the effect of gating number and riser type variations (for sand binder) observed on casting defects, hardness, and impact value. Subsequently, chemical composition and microstructure of recycled aluminum metal from bicycle frames produced through sand mold casting are also evaluated. Three types of risers are bentonite, water glass, and furan resin. The results indicate that mold with two gating system has a low porosity as casting defects. The cast-bike frame produced using furan resin reaches the highest hardness value of 46 HRB compared to water glass and bentonite as the binder of sand-molds. The impact test observes 3.9 J carried out by the ASTM E23 sample at room temperature.

“…Currently, the usage of bikes is quite increased along with the issue of the reduction of air pollution and fossil-fuel use. Bicycles are also healthy alternative hobbies, where there is a positive correlation between human activities and the health [1]. Various designs have been developed, mainly in the frame component which is a crucial component of the bike.…”

The stress distribution and deformation formed by various loading conditions are a crucial thing to be considered during design. Stress and deformation maximum area should be a primary concern, and this study will discuss the stress analysis and displacement of the bike frame (T-I profiles) through the Finite Element Analysis (FEA). Five scenarios loading conditions have been applied which is expected to represent various situations that happen in the actual performance of the bicycle frame. Loading conditions are the static start-up, steady-state pedaling, vertical-horizontal loading, and rear wheel breaking. Cross-section of bike frame comprises into two forms. There are “T” profile on the mainframe and “I” profile on stay. The simulation results in this paper show that von-mises stress ranging from 7.18 - 36.83 MPa which are spreading over several areas of this bike frame such as seat beam, chain stay-seat stay, top beam, and drop out, depending on the position of the loading applied. Subsequently, the maximum deflection that the bike frame from this design is obtained is 0.018 - 0.23 mm (simulation results). Optimization of this bicycle frame is needed for future development.
