Module 2: Bicycle Design Flashcards
What are the Six Bicycle Design Needs
Design Vehicle Operating Space and Dimensions Safety and Security Speed and Momentum Connectivity and Directness All-Season Surface Quality
Name 3 Types of Bicycle Design Vechicles
Road Bike, Children's Bike, Cargo Bike, Electric Bike, Adult Bike, Regular Bike,_ Bikes with Trailers, Recumbent Bikes
What is a Cyclist’s Swept-Path
The swept path is the distance between the front tire path and back tire path created when a cyclist makes a turn
