Electric Bike : Independent Project in Electrical Engineering

Uudelepp, Oscar, Nordén, Ellen, Lowén, Douglas January 2018 (has links)
A group project has been made in which the goal was to build an electric bike. The main focus of the project was to build the surrounding control system of a BLDC motor. A complete BLDC hub motor was purchased. The wheel managed to spin forward but it was never implemented on a bike due to time constraints. This was a rewarding and educational project that can be replicated or improved for future students.

I strävan mot en grönare kommun : En kvalitativ fallstudie över Borås kommuns arbete med klimatväxling på sina enheter. / In pursuit of a greener municipality : A qualitative study on the municipality of Borås work with climate change on it’s units.

Rydholm Allard, Mattias, Insgård, Erik January 2017 (has links)
I detta examensarbete undersöks hur en svensk kommun kan arbeta med klimatväxling för att minska dess ekologiska fotavtryck och negativa effekt på miljön. Miljöfrågor är något som varje kommun brottas med dagligen för att föra arbetet kring hållbar utveckling framåt. Två forskningsfrågor formulerades som skulle ta reda på vilka faktorer som anställda i en svensk kommun upplever ökar miljömedvetenheten och användningen av elcykeln som arbetsfordon.  Tre olika hemtjänstenheter i Borås kommun har undersökts utifrån en kvalitativ ansats ihop med en litteraturstudie. Genom att fokusera på en infrastruktur som främjar elcykelanvändandet, erbjuda utbildningar kring elcykelanvändandet samt arbeta med kampanjer som ökar tillgängligheten på elcyklar kan kommuner skapa en kulturförändring vid val av fordon. Miljöutbildningar, miljöledningssystem och elcyklar ses som fungerande sätt att klimatväxla på, med olika preferenser från person till person beroende på tidigare kunskap och erfarenheter. De tre klimatväxlingsåtgärderna upplevs på olika sätt bidra till att personer agerar på ett mer hållbart sätt. Exempelvis genom bättre resurshantering, eco-driving och via byte av fordon släpps mindre CO2 ut per resa. / This thesis examines how a Swedish municipality can work with climate change to reduce its ecological footprint and negative effects on the environment. Environmental issues are something that every municipality encounters daily to forward the work on sustainable development. Two research questions were formulated that would determine the factors that employees in a Swedish municipality experience increases environmental awareness and usage of electrical bikes as work vehicles. Three different home care service units in Borås municipality has been examined based on a qualitative approach together with a literature study. By focusing on an infrastructure that encourage e-bike usage, provide education on ebikes and creating campaigns that increases the availability of e-bikes, municipalities can create a cultural change in the selection of vehicles. Environmental education, environmental management systems and e-bikes are working ways of climate compensation, with different preferences from person to person, depending on previous knowledge and experience. The three types of climate compensation alternatives are perceived as different ways to help people act more sustainable. For example, through better resource management, education in eco-driving and lesser CO2-emissions per trip by changing vehicle.

Att sadla om och styra mot hållbar mobilitet : Användares perspektiv på hållbarhetsinitiativet LinBike - Linköpings elcykelpool

Holmsten, Jonathan, Arnåsen, Joakim January 2020 (has links)
Linköpings kommun invigde hösten 2019 en elcykelpool kallad LinBike i syfte att bidra till stadens utveckling och nå klimatmålen. Denna studie syftar till att undersöka användarna av LinBike för att förstå varför den används och huruvida den kan bidra till fler hållbara resor. Genom kvalitativa gatuintervjuer med 24 användare har fem olika mobilitetstyper identifierats som sammanfattar användarnas förhållningssätt till systemet. Analys av resultatet visar att elcyklarna främst används tack vare tjänstens bekvämlighet och prisvärdhet. LinBike bidrar till att användarna i många fall kan genomföra sina vardagliga resor enklare än innan. Förbättringsåtgärder föreslås som anses nödvändiga för att tjänsten ska behålla användare och bidra till en mer hållbar mobilitet. Studiens slutsatser är bland annat att klimatsmarta mobilitetstjänster bör fokusera på att vara smidiga och lättillgängliga för att locka användare. LinBike som färdmedel ersätter idag främst andra hållbara transportmedel och därför kan det inte konstateras att tjänsten bidrar till en mer hållbar mobilitet. / Linköpings municipality has during the autumn of 2019 established an electric bike-sharing system called LinBike with the purpose to contribute to the city’s development and reach its climate goals. The scope of this thesis is to study the users of LinBike to understand why it is used and whether it contributes to a sustainable mobility or not. Through qualitative street interviews with 24 users, five types of mobility users have been identified which summarize the users attitude towards the system. Analysis of the results demonstrate that the E-bikes are used mainly because of the convenience and the price of the service. LinBike helps make everyday travel easier than before. Improvement measures are proposed which are considered necessary for the service to maintain users and contribute to a more sustainable mobility. Conclusions are that climate-smart mobility services should focus on being comfortable and accessible to attract users. LinBike users usually replace other sustainable modes of transportation and thus it cannot be concluded that the service contributes to a more sustainable mobility.

Railway Mobility Hubs: A feature-based investment return analysis

Hidalgo González, Guillermo, Queirós, António January 2019 (has links)
While there has been considerable research regarding the role of Mobility Hubs in cities and transport networks, significant investment is required to develop these facilities. It is the correlation between investment, new users’ attraction and revenue generation that is the key for a sustainable development of Mobility Hubs and this investment must, therefore, be correctly assessed and targeted. This study aims to develop a methodology to determine the viability of investing in Mobility Hub features, weighing the investment on different Hub features and services against expected potential benefits and revenue generation, addressing the question: Can investment in Mobility Hub features be justified and, if so, which features maximize its expected positive impact? Based on a review of literature and definition of possible Hub features as variables, secondary research data was compiled to enable the analysis of expected impacts of each variable/feature in terms of new user’s attraction and revenue generation, which was then used to develop individual Net Present Value analysis of each feature. The result of these analysis demonstrates and concludes that different Hub features have the potential to generate substantially different investment outcomes, and that each feature should be analyzed individually prior to investment decision. It was also concluded by this research that the proposed assessment methodology can be used for future research on other listed Hub features, albeit with the constraint that primary data will be required when secondary research data is not available.

Applying strategic design to stand out in the cargo bike market. : Development of a cargo bike for non-cargo bike people. / Tillämpning av strategisk design för att sticka ut på lastcykelmarknaden. : Utveckling av en lastcykel för lastcykelskeptiska.

Mikkelsen, Anna, Wernberg, Moa January 2019 (has links)
This report presents a master’s degree project in Integrated Product Design at KTH Royal Institute of Technology in Stockholm, on behalf of the company Rawbike. The purpose was tod evelop a design and construction proposal for a cargo bike from a strategic market perspective, that could broaden the audience of Rawbike to include more female users. The Rawhauler is a powerful cargo bike with attitude for those who need an agile, multifunctional and modular cargo solution. The Rawhauler makes it possible to carry heavyloads and climb the steepest of hills while having a pleasant biking experience in crowded commuter traffic. Literature studies and strategic tools were used to design a branding strategy where a smallcompany like Rawbike can develop a strong brand to stand out in the crowd. User centredstudies were conducted to ensure a product well adapted to the needs and wants of its users. The insights gained from these two fields were then used to develop a competitive concept thatboth extended the existing portfolio and appealed to the whole Rawbike community, regardlessof gender. / I denna rapport redovisas ett examensarbete på mastersnivå inom utbildningen Teknisk Design på Kungliga Tekniska Högskolan i Stockholm, på uppdrag av företaget Rawbike. Syftet med projektarbetet var att skapa ett marknadsstrategiskt design- och konstruktionsförslag på en lastcykel som skulle kunna bredda Rawbikes befintliga publik och inkludera fler kvinnliga användare. Rawhaulern är en kraftfull lastcykel med attityd för dig som behöver en smidig, multifunktionell och anpassningsbar lastlösning. Rawhaulerns möjliggör för att kunna ta rejält med last där du kan bestiga även de brantaste av backar och ha en härlig cykelupplevelse i trång cykelpendlingstrafik. Litteraturstudier och marknadsstrategiska verktyg användes för att utforma en varumärkesstrategi där ett litet företag som Rawbike kan sticka ut ur mängden med ett starktvarumärke. Användarcentrerade studier genomfördes för att kunna skapa en produkt välförankrad i användarens behov och begär. Insikterna från dessa två områden användes sedan för ta fram ett konkurrenskraftigt koncept som både utökade befintlig produktportfölj och kunde gå hem hos alla, oavsett kön, i Rawbikes community.
