A strong fit for commuters and urban riders who want portable, keyless security for short stops, errands and everyday bicycle parking.
The ULAC STREET FIGHTER Neo Chain Lock Combo is a flexible everyday lock for commuters, shoppers and urban riders. Its 100 cm heat-treated hardened-steel chain wraps around a bicycle frame, seat post or suitable fixed object, while the resettable combination mechanism gives you keyless access with up to 10,000 possible combinations.
At 540 g, it is straightforward to carry on the bike or in a backpack. Use the included ULAC Velcro strap to keep the folded chain tidy, or secure it around the top tube or seat post while riding. The high-quality nylon sleeve helps protect your frame’s paintwork from chain contact and scratches.

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.
