CAD and Finding Bike Frame Manufacturer
This is when I started to look for bike frame factories once the CAD is accurate and ready. I have viewed plenty of factories, hope they would make my bikeframe. But because of it is only a one off project and it will not get them any profit, most of them turned me down. Olympic Pro Manufacturing Co. took my order and even sponsored my bike frames. They made two frames for me for nothing. I am so grateful of them.

PROTOTYPES & PARTS
The Making of Prototypes
Made prototypes with cardboards at first and went on trying out ways to attached the bag to the bike, used aluminum, epoxy tooling board, and leather with lathes machine, milling machine, 3D printer. Sent the frame for spray painting and picked the parts from different manufactures. Put the bike together to see how it works. The cords of normal gear and brakes inturrupted the aesthetic of the bike. So i have changed it to internal kickshift coaster brake gear hub to have a clean shape.

CHOCOBIKE RIDING
ChocoBike Riding When riding a bike, there is a 15 20 cm width of space between two legs where briefcase/bag can be placed. Having the bag right infront of the rider's eyes can make sure the belongings are safe and hard to be snatched. The internal rear gear hub give the whole bike a clean shape, allows riding bikes more intuitive and need less of maintenance caring.

BAG DESIGN
The Bag Design
The bag is design specifically for chocobike. The design focus on the functions. Aesthetic of the bag is to look simple, modern, clean cut, and being stylish without any dramatic logos or patterns. Handles of the bag bend inwards which allows the user to grab the handle easily, and will not get in the way when riding. The top of the bag has a flat area that can place the phone. Having the phone locked on top of the bag can assure the phone will not fall out of pockets when riding. It also let the riders listen to the navigation, music or having a glance of the map without stopping to look at it every few minutes.
