Sweet-Cycle System Requirements Document

1. Introduction

The Sweet-Cycle project aims to develop an online platform for ordering bicycles, catering specifically to individual buyers. This document outlines the system requirements necessary to build and operate the Sweet-Cycle website effectively.

2. System Overview

Sweet-Cycle is an e-commerce platform designed to facilitate the purchase of bicycles by individual consumers. The system will provide a user-friendly interface for browsing, selecting, and ordering bicycles, along with features to enhance the shopping experience.

3. Functional Requirements

• As a User, I should be able to browse a catalog of available bicycles.
• As a User, I should be able to filter bicycles by type, size, and price.
• As a User, I should be able to view detailed information about each bicycle.
• As a User, I should be able to add bicycles to a shopping cart.
• As a User, I should be able to proceed to checkout and place an order.
• As a User, I should be able to create and manage my account.
• As a User, I should be able to view my order history.

4. User Personas

• Individual Buyer: A consumer looking to purchase bicycles for personal use. They value ease of use, detailed product information, and a seamless checkout process.

5. Core User Flows

• Individual Buyer browses bicycle catalog -> filters by preferences -> views bicycle details -> adds to cart -> proceeds to checkout -> completes purchase -> receives order confirmation.

6. Visuals Colors and Theme

• primary: #2A9D8F (Teal)
• primary_light: #A8DADC (Light Teal)
• secondary: #E76F51 (Coral)

7. Signature Design Concept

The Sweet-Cycle homepage will feature an interactive 3D bicycle showcase using @react-three/fiber and @react-three/drei. Users can rotate and explore a 3D model of a bicycle, with hotspots that reveal detailed specifications and features upon hover. The background will subtly shift colors based on the time of day, creating a dynamic and engaging user experience.

8. Interaction Model & Motion Direction

The landing page will employ a "parallax" interaction model, with layered depth effects as users scroll. Decorative elements like bicycle parts and gears will move at different speeds, creating a sense of motion and depth. The internal pages will maintain a "static" interaction model for clarity and ease of navigation.

9. Non-Functional Requirements

• The system should support high availability and handle up to 10,000 concurrent users.
• The website should load within 3 seconds on a standard broadband connection.
• The platform must comply with data protection regulations applicable in India.

10. Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local orchestration: Docker, docker-compose
• Server-side orchestration: Kubernetes

11. Assumptions and Constraints

• The platform will initially target the Indian market, with pricing displayed in INR.
• The system will assume users have basic internet access and modern web browsers.
• The project will adhere to a budget constraint, focusing on essential features for launch.
