A bike lock is not just a bike lock.
ULAC is a Taiwanese bicycle-lock brand established in 1982. It began as an original equipment manufacturer producing high-security solutions for global industry leaders, then transitioned to an independent, consumer-focused brand in 2015 with the Si Works silicone lock collection.
ULAC develops security products through its in-house U-Lab research and development centre and operates its own manufacturing facility. Its work includes integrated alarm systems, NFC smart-lock technology and biometric authentication, alongside conventional bicycle-lock hardware and design-led products.
