A bicicleta é hoje reconhecida a nível internacional não apenas como instrumento lúdico, mas
também como um meio de transporte urbano promotor de saúde. Pedalar constitui um modo
saudável, limpo, económico e divertido de mobilidade que traz muitas outras vantagens e que
deve ser cada vez mais adotado pelas pessoas, sobretudo pela população mais jovem e nas
deslocações pendulares para a escola ou trabalho.
No contexto europeu e apesar de dispormos de ímpares condições de diferenciação positiva, o
nosso país apresenta um dos menores índices de utilização dos modos suaves de mobilidade,
para o qual tem contribuído um planeamento orientado para o transporte rodoviário.
Recentemente o “Projeto Mobilidade Sustentável” deu um passo na promoção da mudança de
paradigma no contexto nacional de redes de mobilidade suave, imperativo nos dias de hoje.
Para melhorar o desempenho e diminuir o esforço do uso da bicicleta tradicional nas subidas,
a opção recai na bicicleta elétrica assistida, pois é um veículo híbrido que permite a realização
de percursos de forma mais cómoda e rápida.
A presente dissertação teve por objetivo projetar uma bicicleta elétrica de elevada eficiência e
performance e em simultâneo disseminar conhecimento rigoroso referente a esta forma de
deslocação, ajudando a sensibilizar os intervenientes acerca dos grandes benefícios do uso da
bicicleta elétrica, promovendo a mobilidade sustentável.
Após um rigoroso e detalhado estudo cinemático do veículo de duas rodas e com base nas
performances que se pretendem alcançar, foi elaborado o projeto da bicicleta, selecionados os
componentes que o integram e expostos os fundamentos teóricos que justificam a escolha dos
mesmos. O desenho do quadro teve por base um convencional, adaptado para integrar as
baterias. Foram realizadas diferentes simulações do estudo cinemático e diversos cálculos
referentes a consumos, autonomia, custos associados, impacte ambiental, bem como a
contabilização de todos os benefícios resultantes da utilização da bicicleta elétrica.
Para transmitir de forma eficaz as qualidades da bicicleta projetada, foi criada a marca, o
slogan, concebido o logotipo e construído o website onde estão publicados os dados gerais do
projeto. O referido website contribui também para a divulgação, sensibilização e promoção do
uso da bicicleta elétrica.
A opção pela utilização da bicicleta como forma de deslocação alternativa ao automóvel,
nomeadamente em meio urbano, apresenta inegáveis vantagens que justificam plenamente a
promoção deste modo suave de mobilidade.
ABSTRACT: Nowadays, the bicycle is recognised internationally not merely as a form of leisure but also as a means of urban transport and a promoter of good health. Cycling is a healthy, clean, economical and fun way to be mobile that brings many additional advantages and it should be adopted increasingly, especially by younger people and by those commuting to school or work. In Europe, even though we have unmatched conditions of positive differentiation, our country has one of the lowest rates of use of soft forms of mobility. Planning aimed at road transport has contributed largely to this. Recently, the “Sustainable Mobility Project” took a step towards promoting a change of paradigm in the context of national networks of soft mobility, which is imperative nowadays. To improve performance and diminish the effort required when using the traditional bicycle uphill, we have opted for an assisted electric bicycle, which is a hybrid vehicle that allows faster and more comfortable commuting. The present dissertation aims to present a highly efficient, high performance electric bicycle and, simultaneously, to disseminate accurate knowledge regarding this form of transport, helping to raise awareness of the great benefits of using the electric bicycle and promoting sustainable transport. After a rigorous and detailed study of the kinematic two-wheeled vehicle, and based on the desired levels of performance, the bicycle project was developed, the component parts of the project were selected and the theoretical foundations that justify our choice were presented. The framework was based on a conventional design, adapted to carry the batteries. Different simulations of the kinematic study were carried out and various calculations were made for consumption, autonomy, associated costs and environmental impact, as well as all the benefits resulting from using the electric bicycle. To communicate the qualities of the projected bicycle efficiently, the brand and slogan were created, the logo was designed and the website was built to publish the general data of the project. The website also contributes to dissemination, awareness raising and promotes the use of the electric bicycle. Opting to use the bicycle as an alternative form of transport to the automobile, especially in urban contexts, presents undeniable advantages that fully justify the promotion of this means of soft mobility.
