ORA Engineering Co. LTD. (鈦郁工業股份有限公司) is a manufacturer of bicycle frames and parts, located in Taichung, Taiwan. Founded in 1996, the company initially served as an Original Equipment Manufacturer (OEM), specializing in producing custom designs for major cycling brands such as Falkenjagd from Germany , StarlingCycles from the United Kingdom and Commencal Bicycles from Andorra. ORA Engineering uses titanium fabrication, though it also works with stainless steel and chromoly materials.

History
ORA Engineering was established in 1996 by Jim Hsu as a titanium welding factory. The company embraced gas tungsten arc welding techniques, a skill acquired from Japan, marking its initial steps in the industry.

In 2006, ORA co-developed its first bike frame in collaboration with the Taiwanese Titanium bike brand Rikulau, utilizing Reynolds 953 maraging stainless steel. .

By 2010, ORA Engineering expanded its operations to a new 3,300 square meter facility in Houli, Taichung. This move featured several eco-friendly initiatives such as wastewater treatment using a chemical coagulation process, the installation of a ventilation system based on Bernoulli's Principle, and the inclusion of high-precision CNC lathe and milling machines. The facility also houses T6 heat treatment furnaces by B.M.I and a bilateral 4-spindle auto milling machine, enabling ORA to maintain a complete in-house production line focused on Titanium alloy.

In 2023, Agnes Hsu, the daughter of founder Jim Hsu, became CEO. This transition marked a new era for the company, which was further recognized that year with the Taiwan Mittelstand Award by the Industry Development Administration (MOEA) of Taiwan.
