Chi-Fly

 For this action project we redesigned bikes for different people living different lifestyles. My partner and I were given the persona of a young man living in uptown, that needs a bike that is efficient to commute with and light to carry. We are most proud of our bikes frame and innovative fender; what makes the bikes frame so special is that it is steel and hollow allowing to be very strong but lightweight. The innovations we made on the fender allow it to fold into a small cube that you can fit into your back pocket or into a small bag.Along with learning how to make bike innovations we studied. Diameter, Circumference, Force, Area of the Circle, graphing circles and radius. Understanding these concepts allowed us to make more efficient bikes. We were able to calculate things like gear ratios which are very important when designing bikes.

The young man we were designing her bike for is a high school student Looking for a bike that is fast and efficient to ride, the bike also needed to include a unique visual aspect. The bike also needs to be lightweight because he lives on a top floor apartment. The bike me and my partner were able to design meets these criteria is to a tee. For example when it comes to the bike being efficient the hollow steel frame allows it to be strong and lightweight, making it easy for him to carry it up to his top floor apartment. Having a fender that is collapsible allows him to fit it into his bag and it won't take up too much space that can be used for school supplies. The visual aspect that makes the bike unique is the color changing paint that reacts to sunlight, when the bike is in a dark space it turns dark blue and when the bike is exposed to sunlight turn the light shade of blue. When it comes to the mechanics of the bike the wheel to gear ratio is high, allowing you to do less work peddling but still allowing you to go a very far distance. When going uphill the rider will build a lot of potential energy, The kinetic energy will allow the rider to coast with less petals. When interviewing a bicyclist I found that one of the main challenges they face is biking up and down hills. " biking up hills is one of the worst parts of biking but within a fishing gear setting it can make the ride easier."

The diameter of the bikes wheels are 24.5 inches and the circumference of 76.9 inches the area of the wheels is 471.4. Which is an identical measurement to most hybrid, road and fixie bicycles. This happens to be the type of bike we need to design to fit our persona. The gear ratio we chose for bike is two petals for six rotations.Along the bike to travel 2 m/s, the bicycles commute is 15 minutes this allows the bicyclist to travel 1800 m in 15 minutes.
