Yipsan Bicycles:

YiPsan Bicycles was conceived by Renold Yip to continuing the craft of framebuilding by single person workshop. YiPsan’s goal is to integrate modern fitting concept, frame tubing and components with traditional building skills. YiPsan bicycles are built by hand one at a time and every bicycle is unique.

Fit, ride quality and design for application are at the heart of YiPsan Bicycles. The more specific your requirements are the better the design will be. Your experience and input along the design and build process is also very important.

Renold, the sole worker of YiPsan, was raised in Hong Kong, China., obtained his bachelor of engineering in the UK and immigrated to the US since 2002. Since then, he has been working at local bike shops, building bicycles, certified as a fit specialist and enjoying living in the east coast, west coast and the rockies.

Firecracker fixed gear:

The Firecracker was conceived as a celebration to Chinese New Year  during NAHBS Portland. Show time that year happens to start on the second day of Chinese New Year and firecrackers are fired during this time of year to celebrate the beginning of a new year and to rid of negative Chi.

Firecrackers come originally from bamboos being heated and as the air inside the hollow segment expand, it finally explode and split the bamboo making a loud pop sound. It is used only for ceremonies.

The nature of firecracker parallels a fixed gear bicycle in the way of its explosiveness, simplicity and pure celebration to its event.
