Best Bike Cable Locks of 2026

Seventy inches is a shade under six feet, and that length is the whole argument for this one. It threads through a frame, both wheels, and still has room to go around a rack or a post, which is more coverage than most locks this simple offer. The cable is 8 mm, so it is a middleweight: enough to send a casual thief looking for an easier bike, light enough to coil and carry.

Two small details earn their keep. The plastic coating is weather resistant and keeps the steel off your paint, and a cover over the keyway shuts out grit and water — the sort of thing you notice a year in, when the key still turns on the first try. At 0.28 kg it disappears into a backpack, which is where ours usually lives.

It is the least expensive lock here, and we think it is the best value of the group for a bike that is never far from you: a café stop, a school rack, a lobby. Nothing about it feels precious, which is the point — you won't baby it, and you won't leave it at home because it is awkward to carry.

The head slides along the cable and locks wherever you stop it, which is a different idea from a fixed loop. Thread it through a wheel, a frame, a kayak handle, a trail camera housing, pull it snug, and nothing hangs slack for someone to work with. We like that for anything with an awkward shape and a hole in it, because the lock takes the shape you give it.

It comes as a two-pack with four keys, and six feet of cable wraps a tree trunk or a roof bar with room to spare. The catch is the cable itself: 3/16 inch, about 5 mm, which is thin even for a cable lock. This is a lock for keeping gear from walking off, and for keeping honest people honest.

As a bike lock it sits behind the thicker picks here — 5 mm of steel is a deterrent, not a defense, and a bike parked downtown all day deserves more. As the lock that lives in the trunk for cameras, kayaks, ladders, and job boxes, it is the most versatile thing in this group.

Ten feet sounds like more than you need until you are gathering four bikes onto one rack. The number to hold loosely, though, is the working length: a coiled cable pulls back on itself, so what you can actually thread is shorter than ten feet. Size up if you are close to the limit rather than assuming the figure is generous.

What you are buying is reach plus hardware: 10 mm marine-grade steel under a vinyl coating, a zinc alloy combination lock, and an end slim enough to pass through tight openings like kayak scupper holes. It is designed for water sports and happens to be very good at bikes, which is the reverse of most locks here.

The four-digit combination is resettable, so you can set something you will remember, and the coil stores small on a rack or in a car. Set that code at home with the instructions to hand, rather than in a parking lot on the first morning you own it.

For us this is the pick for a family's worth of bikes, a bike plus a trailer, or a roof load of kayaks — the jobs where four feet simply cannot reach. It is the one lock here that turns an awkward load into a single lock-up instead of three.

Schwinn labels this a Level 1 lock, and we appreciate the honesty. Level 1 means deterrent: it stops someone walking off with your bike, and it will not stop anyone who came prepared. Knowing that up front is genuinely useful, because it tells you where this lock belongs — short stops, busy places, daylight.

Six feet of cable is why it earns a place. On a crowded rack that is the difference between getting around the post at all and giving up and locking the bike to itself; with the frame, both wheels, and a helmet on board, there is still cable to take up. The bracket keeps it on the bike between trips, two keys come in the box, and the vinyl jacket protects the paint.

The trade-off is the 8 mm cable. It is easier to handle and lighter on the frame than the 12 mm picks here, but it is also the diameter a bolt cutter goes through first. If the bike sits outside a train station all day, put your money into heavier security; for errands, school runs, and holiday racks, the reach is worth more than the extra steel.

GRIFEMA's pitch is weather. The lock body is sealed, the finish is built for rain and humidity, and the cable is 12 mm — the same diameter as our top pick — on a 4 ft coil with a bracket, two keys, and a head that snaps shut without the key.

That makes it the sensible choice for a bike that lives outside and gets ridden through winter. The sealed body is the part we care about most: grit and water in a keyway is what turns a working lock into a fight at the end of a wet ride, and the coating does the same favor for your frame. Nothing about it is fussy, and for a commuter bike parked in the same spot every day, that is the entire brief.

No key to lose is the whole argument here, and for a family's bikes it is a good one. Two 4 ft cables come in the pack, and both open on the same four-digit code, so a kid can lock up without a key ring and you can open either bike without hunting for the right key.

The cable is 8 mm braided steel in a vinyl jacket — standard for the money — with jog-dial wheels you spin rather than pull. It is a deterrent for the ten minutes you are inside a shop, and the pair covers two bikes or a bike and a trailer without much thought.

What tips it for us is how little there is to go wrong: no key to bend, snap off in the keyway, or leave in a coat pocket at home. For school runs and campsite bike piles, that simplicity is worth more than another two millimeters of cable.
