On the following pages we are going to describe the development of an “e-bike” motor. There are some requirements for the motor, which have to be considered. Today there are already different types of e-bikes. Almost all of them have fixed batteries and drive units. That means it is not possible to change the motor onto another bike, at least it would be very difficult. Our task now is to develop a motor, which is easily to change onto other bikes.
To accomplish such a development it is necessary to make a proceeding plan. We took the structure from the book (..) as a guideline.
• The first step is the Product Plan. It consists some pre planning, the mission statement to define the requirements and the project plan which is the schedule for the development.
• For the next we tried to Identify Customer Needs. To gather some data about customers we made a questionnaire. This data we tried to interpret in a customer needs table we also made a hierarchy of the most important requirements. After that we selected the customers, which could come in question.
• In third step we established Target Specifications. One of it was the product specification with metrics and the target values.
• The next step was the Generation of the Product Concept. Here we made different concept to for gaining ideas e.g. brainstorming, 6-3-5 – method. After that we researched on the Internet and made benchmarking to get more and better information about the different parts of the product.
• The last step was the Selection of the Product Concept. We developed 3 different concepts and decided by the pros and cons about the final one we should choose.
On the basis of these five points our report is structured.

Chapter Summaries
Introduction: This chapter introduces the project's goal: to develop an easily interchangeable e-bike motor. It outlines the development process, highlighting the importance of considering existing e-bike limitations and the adoption of a structured approach guided by the book "Product Design and Development" by Ulrich and Eppinger. The chapter briefly summarizes the five key stages of the development plan: product planning, identifying customer needs, establishing target specifications, generating product concepts, and selecting a product concept.
Questionnaire: This chapter details the methodology used to gather customer needs. Focusing on elderly individuals as the primary target group, the study utilized telephone and email interviews due to time constraints and language barriers. The questionnaire was divided into two parts: general bicycling habits and personal information, and specific questions regarding an e-bike assistance system. The results, including customer statements and interpreted needs, were compiled into Table 1, illustrating common preferences, dislikes, and suggested improvements related to bicycling and the desired features of an e-bike assistance system. The chapter highlights the challenges in gathering data from the target demographic and the methods used to overcome them, emphasizing the international scope of the interviews.

Frequently Asked Questions: E-bike Motor Development Report
What is the main objective of this report?
The report documents the development process of an easily interchangeable e-bike motor, focusing on a structured approach guided by customer needs, target specifications, and concept generation. The ultimate goal was to select a suitable design for the motor.
What methodology was used to gather customer needs?
A questionnaire was employed, using telephone and email interviews due to time constraints and language barriers. The target group was elderly individuals. The questionnaire covered general bicycling habits, personal information, and specific questions about desired features in an e-bike assistance system. Challenges in gathering data from this demographic and the methods used to overcome these are discussed.
What are the key themes explored in the report?
Key themes include customer needs identification and analysis, the development of an interchangeable e-bike motor, concept generation and evaluation, product specification and target values, and design considerations specifically for elderly users.
What stages of the development process are covered?
The report covers five key stages: product planning, identifying customer needs, establishing target specifications, generating product concepts, and selecting a product concept. These stages align with the principles outlined in Ulrich and Eppinger's "Product Design and Development".
What are the different design concepts explored?
The report explores several design concepts for the interchangeable e-bike motor, including the hub wheel concept, the top wheel concept, and the side-wheel concept. Each concept is analyzed and evaluated based on the identified customer needs and target specifications.
What is the structure of the report?
The report includes an introduction, a detailed explanation of the questionnaire methodology and results, a hierarchical organization of customer needs, an analysis of relative importance of features, product/target specifications, conceptual design ideas, a literature review, and a conclusion detailing the chosen design concept.
What are the key findings of the customer needs analysis?
The customer needs analysis, presented in Table 1 (not included in this HTML summary), details common preferences, dislikes, and suggestions for improvement regarding e-bike assistance systems, particularly from the perspective of elderly users. The analysis highlights the challenges in gathering data from this demographic and the methods employed to ensure the reliability of the results.
What are the key words associated with this report?
Key words include: E-bike motor, interchangeable design, customer needs, elderly users, product development, conceptual design, target specifications, questionnaire, benchmarking, and design concepts.
Where can I find more information about the specific design concepts (Hub wheel, Top wheel, Side-wheel)?
Detailed information on the hub wheel, top wheel, and side-wheel concepts, including their respective advantages and disadvantages, can be found in the corresponding chapters of the full report.
What is the significance of considering elderly users in the design process?
The report emphasizes the importance of designing the e-bike motor with the specific needs and limitations of elderly users in mind. This user-centric approach is crucial for ensuring the usability and accessibility of the final product.
