• Reasons for Material Selection
  • Lightweight
  • Does not need to be durable
  • Easy and cost efficient to make

  • To give a nice finish (aesthetics)
  • To provide gripping capability
• Forces Applied to the Component
  • Twisting torque when rider wants to increase the velocity of the scooter
  • Forward pushing motion will put stress on horizontal handlebar
• Choice of Manufacturing Process
  • Injection molding is easiest and most cost effective method of producing mass amounts of the same component
  • Turning is the easiest way to manufacture axially symmetric parts
  • Milling is easy for simple non-axially symmetric parts
• Particular Shape
  • Circular to allow for a hollow center which makes it possible to place over the handle bars
  • Allow for easy grip and turning by the rider
