When designing an item, one must first ask questions, such as "Will it benefit a specific user compared to a general audience", "If other people will wish for it" and "How is it better compared to different brands". This is what my class, Design and Engineering, is trying to answer. In this unit we had specifically focused on subjects that could help us design items such as graphing, Kinetic & Potential Energy, and much more. We had also met with multiple organizations such as Divvy, BFF Bikes, and others.

(meant to show the calculations of a graph)

What my class and I had to create was a small model for a bicycle that was meant for a specific person in Chicago. Not only that, but we also had to show the calculations on why it was better compared to other certain designs. One of the main struggles I had with this assignment was time and how my partner and I had to do multiple re-dos with either calculations or design on our model. There was also the task of working with a partner and the separation of communication. It was a bit of a struggle, but worth the effort.

When creating bikes, you could either remodel the bike, or create add ons. Each one brings benefit to the user, while having certain effects onto the movement or speed of the bike. When I say remodeling, I would mean something such as an Evo or Bicymple, where the idea of a bike is questioned and remade. For Bicymple, it would be the loss of the chain and allowing a new way to ride a bike.

Add ons, on the other hand, is the idea where the body of the bike stays the same, while certain parts are specifically built upon to make the experience greater. An example would be a Denny with its lock up handle. It doesn't affect how the bike is ridden, but it does help with the experience. The bike Denny also has an electric power assist, which could help going up certain terrains.

This is what my partner and I thought of when creating a bike for our user. Travis, a 16 year old boy, wishes to bike 5.5 miles to school. Since he passes the coast of Lake Michigan, he faces harsh winds and amplified weather. He lives up three flights of stairs within his apartment. He wishes for a bike that can suit all his needs while also being fast enough to get to school.

“Sure, I think most bikes are either aluminum, steel, or some bikes are carbon fiber. So Carbon Fiber is really, really, expensive, and really, really light.” - Marcus

This quote is from a GCE instructor who I (JN) had the pleasure to interview. How this quote inspires the design of my bike! It brings up the idea of mass and weight, and shows that there should be a remodeling rather than an add on. The problem for most bikes is when lifted or brought by hand, the ride could have trouble only because of the fact that it’s too heavy. My bike, however, uses less of the same material. Yet it is built to balance weight like a bridge.

For my bike (The Breezer), I had to create a design and remodel it so that it wastes less money, is 3/4th as light, resistant to the elements, and impressive to look at. Based around the design of modern bridges and advanced architecture, The Breezer is the average body of a bicycle with 1 cm poles with an integrated structure rather than one tube. The handles, pedal mechanism, seat, and wheels all use similar materials compared to normal bikes. This bike benefits users and is better than other models because:

A.It is a well designed bike that pleases the eye with its geometry and can be see through to see what is inside of the body.

B. Uses less metal and therefore creates less weight that also has more creative ways to be locked down to a side of a wall.

C. The elements can easily pass through rather then push against the metal, like bars compared to boards.

It also has certain add ons such as bending handles to lessen storage space, and mountain tires dedicated to resist most of the elements. Finally, the seat has a lovely design that suits the bottom of any person.

Here are the calculations for The Breezer written down. The calculations show equations for circumference, diameter, and radius of the wheel. Not only that, the conversions of miles to meters, speed, rotations, and so much more. There's also the calculations for the kinetic energy and velocity of the bike.

Next, we have both the original design as well as the model. The add ons being the weather resistant or mountain bike designed wheels, its bendable handles that allow easier storage, and its comfortable seating. It also shows what the tube design could have looked like.

Finally, we have the gear ratio, which determines the explanation of how fast the bike needs to be.

(For this bike, I believe the best solution would be to have the gear ratio of 48/12.

The reason I believe this is even though the wheel is for mountain biking, The Breezer will always be within

the limits of the city. Therefore, it wouldn't make sense to either add multiple gears or

design the bike to go uphill. Not to mention that time is especially important for school, and being faster rather then durable would create a huge benefit for Travis.)

In conclusion, my partner and I tried to create a bike that was not only sustainable for one person, but for anyone. Travis is not the only person who has these problems, and it would benefit many to have a bike that's resistant to the weather. The two obstacles creating this project were redoing some of the calculations as well as communication with my partner. There was also confusion with creating the model and how much time was allowed. Besides that, I personally believe this project was a success.
