ULAC Street Fighter Nuvo Chain Combo Lock 5mm × 100cm
Flexible Security. Cut-Resistant Cover. Key-Free Convenience.
The ULAC Street Fighter Nuvo Chain Combo Lock is a practical security option for everyday cycling, café stops and short periods away from your bike. Its 100cm length provides enough reach to secure a bike to many racks and fixed objects while remaining compact enough to transport on the bike.
Inside the protective sleeve is a 5mm heat-treated hardened-steel chain. The outer UHMWPE fibre covering adds cut resistance while helping protect the bike’s paintwork from scratches.
Heat-Treated Steel Chain
The Street Fighter Nuvo uses a 5mm heat-treated hardened-steel chain designed to resist cutting and tensile force.
Its flexible construction makes it easier to position around bike frames, wheels and fixed objects than a rigid lock.
Cut-Resistant UHMWPE Sleeve
The chain is covered by an ultra-high-molecular-weight polyethylene sleeve. UHMWPE is a strong and abrasion-resistant fibre that provides more cut resistance than a conventional nylon chain covering.
The sleeve also prevents the steel links from contacting the bike directly, helping protect painted frame surfaces during locking and transport.
Key-Free Combination Locking
A resettable four-digit combination mechanism provides up to 10,000 possible combinations.
There is no key to carry or misplace, making the lock convenient for commuting, family bikes and regular café stops. The combination can be changed to a number that is easier for the owner to remember.
Useful 100cm Length
The 100cm chain provides enough reach for securing a bike to many standard racks, posts and other suitable fixed objects.
Its flexible shape also makes it easier to secure awkward frame designs or include a wheel when the locking point allows.
Easy to Carry on the Bike
The supplied ULAC hook-and-loop strap allows the chain to be bundled for storage.
It can also be wrapped around a suitable top tube or seatpost while riding, provided it is secured firmly and cannot interfere with steering, pedalling, suspension or the wheels.

Who Is This Lock For?
The Street Fighter Nuvo is suited to riders wanting a convenient, portable lock for café stops, errands and short periods in lower-risk locations.
Its combination mechanism also makes it useful for family bikes or situations where several people may need to use the same lock. For extended parking, high-value bikes or higher-risk locations, we recommend using a heavier security-rated lock or combining the Nuvo with a second lock.
Perfect For
✔ Café and bakery stops
✔ Short errands
✔ Recreational rides
✔ Commuting in lower-risk locations
✔ Securing bikes within sight
✔ Family and shared bikes
✔ Riders who prefer a combination lock
✔ Protecting frame paint from exposed chain links
Our Thoughts on the ULAC Street Fighter Nuvo
The Street Fighter Nuvo is a useful lock to carry when you need something more secure than a lightweight cable but do not want the bulk of a heavy-duty chain. The 100cm length provides good flexibility around bike racks, and the covered chain is less likely to mark the frame during use or transport.
The combination mechanism is particularly convenient for café rides because there is no small key to remember. We recommend choosing a code that is memorable to you but not obvious, and checking that the dials have been fully scrambled after locking the bike.
This is best treated as a portable everyday lock rather than maximum security for leaving an expensive bike unattended for hours. For higher-risk areas or overnight storage, we would pair it with a quality D-lock or use a heavier security-rated chain.
