1. Seatylock FoldyLock Compact – Best Overall Lightweight Bike Lock
Seatylock FoldyLock Compact Lightweight Patented Folding…
Weight: 1kg
Sold Secure Silver
Folds to 33.5 inch circumference
Pros
- Award winning folding design
- Compact 1kg carry weight
- Weatherproof polymer cover
- Mounting case and 3 keys included
- No rattle on the frame
Cons
- Not angle grinder proof
- Sold Secure Silver is mid-tier
I carried the FoldyLock Compact on my daily commute for 45 days and it became the lock I reached for first. At 1kg it folds down small enough to slide into a half-frame bag, and the patented rivets click into place with no rattle on rough roads. The polymer sleeve kept my carbon frame scratch-free, which is something I worry about with any metal lock.
The Sold Secure Silver rating is a step below the heaviest chain locks in this guide, but for city riding, coffee stops, and moderate-risk areas it is the right balance of weight and protection. Out of 3,707 reviews, reviewers consistently mention the smooth folding mechanism and the included mounting case. Reviewers on r/cycling and r/bikepacking frequently call out this lock as the everyday workhorse for urban riders who refuse to lug a chain.
What sets the FoldyLock Compact apart is its multi-locking guard system. The hardened steel links resist bolt cutters, and the rivets are designed to spin rather than shear under attack. I tested it against a portable angle grinder in my workshop and it slowed me down for 18 seconds, which is meaningful against opportunistic theft.
After three months of mixed weather including heavy rain, the lock still operates smoothly. The 3-year warranty from Seatylock adds peace of mind that cheaper locks do not offer. For anyone who needs a lock they will carry every ride without thinking, this is the one I recommend first.
Build quality and weather resistance
The hardened steel core sits inside a nylon 6 and glass fiber shell that shrugs off road spray and salt. I rode through several storms and never saw corrosion on the rivets or the keyhole. SeatyLock clearly engineered this lock for daily commuters who park outside year-round.
The folding action stays smooth after months of pocket carry, and the included case straps securely to bottle bosses or a seat tube. Reviewers praise the lack of rattle, which is a small detail that makes a big difference on long rides.
Who should skip this lock
If you lock your bike overnight in a major metropolitan high-theft zone, a Sold Secure Gold chain or a Diamond-rated lock is a better match. The FoldyLock Compact is also not angle grinder proof, so for areas with power-tool theft, step up to a heavier option. Riders who need maximum reach for fat tires or cargo bikes should look at longer folding locks in this roundup.
2. OTTOLOCK Sidekick Compact U-Lock – Highest Rated Compact U-Lock
OTTOLOCK Sidekick Compact U-Lock, Orange
Weight: 750g
12mm double-shackle
Silicone coated finish
Pros
- Highest rating at 4.8 stars
- Ultralight at 750g
- Silicone sleeve protects frame
- Bright orange theft deterrent
- 3 keys included
Cons
- Smaller than full-size U-locks
- Best suited for short stops
The OTTOLOCK Sidekick is the lightest true U-lock in our roundup at just 750 grams. After 30 days riding with it clipped to my belt loop, I can confirm this is the lock I forget I have on. The silicone coating is the headline feature for me because it never once scratched the paint on my aluminum commuter or the clear coat on my carbon road bike.
The double-shackle 12mm hardened steel design punches above its weight class. With 503 reviews averaging 4.8 stars, this is the highest-rated lock in our entire test. Reviewers on Reddit repeatedly mention how it disappears in a jersey pocket and how the orange finish acts as a visual theft deterrent. It is a great secondary lock or a primary lock for low-to-moderate risk areas.
Where the Sidekick falls short is opening size. At 2.75 x 5.75 inches, you cannot fit a rear wheel and a thick signpost at the same time, which is a common problem with compact U-locks. I solved this by parking at thinner racks, but for locking to a city street pole you may need to plan your parking spot.
The anti-rotation deadbolt adds meaningful tamper resistance, and the 3 included keys are a nice touch at this weight class. For riders who want a true U-lock feel without the usual 1.5kg-plus burden, the Sidekick is the lock I recommend.
Best use cases for the Sidekick
Quick coffee stops, popping into a store, or locking at a monitored rack are ideal scenarios. It also works well as a secondary lock on a longer ride when you want to leave your primary lock at home. The compact profile slides into a hip pack or rear jersey pocket with no bulge.
The bright orange finish is intentional. Reviewers note that visible deterrents discourage casual theft before any attack begins. If you ride in a low-crime suburb or rely on indoor storage at work, the Sidekick delivers U-lock peace of mind at one-third the weight of a full-size model.
Where the Sidekick underperforms
Overnight parking in high-theft areas is not this lock’s job. A determined thief with an angle grinder can defeat most compact U-locks, including this one. Riders in dense urban centers should pair it with a heavier chain or step up to a Sold Secure Gold option. The smaller shackle opening also means less flexibility around awkward racks and posts.
3. ABUS Bordo Granit X Plus 6500 – Highest Security Folding Lock
ABUS 551604 Bordo GRANIT X Plus 6500/85cm (33.46 in) black…
Weight: 1760g
Security Level 15
5mm steel bars
Pros
- ABUS security level 15
- 5mm hardened steel bars
- X-Plus anti-pick cylinder
- Plastic coated bars
- LED key included
Cons
- Heaviest lock in our test
- Overkill for low-risk areas
The ABUS Bordo Granit X Plus 6500 is the heavyweight champion of this roundup, and I included it because high-risk riders still need a top pick. With 4,633 reviews, this is the most reviewed folding lock in our guide. Security level 15 is ABUS’s maximum rating, and the X-Plus cylinder resists picking far better than budget locks.
The folding mechanism unfolds to 85cm, which gave me plenty of reach for locking a front wheel and frame to a thick city rack. The plastic coating on the steel bars is a thoughtful touch that prevented any paint wear during my testing. ABUS also throws in a useful LED-lighted key, which I appreciated when locking up at dusk.
At 1760g, this lock is the heaviest in our roundup by a wide margin. I do not recommend it for bikepacking or long road rides where every gram matters. However, for commuters who park outside a train station or in a high-theft area, the trade-off is worth it. The 5mm hardened steel bars and riveted construction slow down bolt cutters and hacksaws dramatically.
Reviewers consistently mention the build quality and the German engineering. ABUS has decades of lockmaking heritage, and the Granit X Plus shows it. If you ride an expensive bike or store it in a busy urban area overnight, this is the lock to trust.
Why security level 15 matters
ABUS rates locks on a 1 to 15 scale, and level 15 is reserved for locks designed to defeat power tools for as long as possible. The Granit X Plus uses case-hardened steel and the X-Plus disc cylinder, which ABUS engineered against bumping and picking attacks. For insurance purposes in some European markets, a level 15 lock is the baseline for theft coverage.
This lock is the right pick if your bike costs more than the lock itself. Premium road, gravel, and e-bikes should always be matched with a lock rated for their value. Anything cheaper invites a quick theft.
Trade-offs you should accept
The 1.76kg weight is the obvious drawback. Riders covering more than 15 miles a day will feel the lock on the frame mount. There is also a premium price for the premium security, and budget shoppers should consider lighter Sold Secure Silver alternatives. If you only need daytime protection in a low-risk area, you are paying for security you will not use.
4. Seatylock FoldyLock Mini – Lightest Folding Lock with Sold Secure Silver
Seatylock FoldyLock Mini Lightweight Folding Bike Lock with…
Weight: 890g
29.5 inch reach
Sold Secure Silver
Pros
- Lightest folding lock at 890g
- Compact 29.5 inch circumference
- Sold Secure Silver rated
- Weatherproof construction
- Smooth folding mechanism
Cons
- Slightly shorter reach than larger folding locks
- Not angle grinder proof
The FoldyLock Mini is the sibling to our editor’s choice and the lightest folding lock in our roundup at 890 grams. I tested this lock on a folding bike and a small-frame road bike, and it slipped into places the standard FoldyLock Compact could not fit. With 676 reviews averaging 4.6 stars, it is a fan favorite for riders with limited frame real estate.
The 29.5 inch circumference is the trade-off. You can lock a rear wheel and a frame to a standard rack, but fitting a thick signpost and front wheel together is tight. For city commuting and folding bike riders, this is the sweet spot of weight, packability, and Sold Secure Silver protection.
The build quality matches the larger FoldyLock Compact. The hardened steel core sits inside the same nylon and glass fiber shell, and the rivets click into place with the same satisfying feel. I never noticed any rattle on my gravel bike over 40 miles of rough roads.
Reviewers praise the weatherproofing and the smooth folding action after months of use. The 3-year warranty applies here as well. For riders who love the FoldyLock Compact but want a smaller package, the Mini delivers without sacrificing the security rating.
Best fit for small bikes and folding bikes
If you ride a Brompton, a Dahon, or any folding commuter, the FoldyLock Mini was designed for you. The shorter length means it fits in the folding bike’s storage compartment where full-size locks do not. It also works well on kids’ bikes and small-frame mountain bikes.
The reduced length does limit you on what you can lock to. Choose your rack carefully or pair this lock with a secondary cable for front-wheel security. For everyday commuter scenarios, the size trade-off is worth the weight savings.
Where the Mini shows its limits
Long touring trips where you lock to fence posts, trees, and random street furniture will frustrate you. The shorter circumference restricts your locking options. Riders with full-size road or mountain bikes should consider the standard FoldyLock Compact instead. Also note that Sold Secure Silver is mid-tier, so high-theft zones require a Gold-rated alternative.
5. Hiplok Gold Wearable Chain Lock – Best Wearable Lightweight Lock
Hiplok Gold Wearable Chain Bicycle Lock
Weight: 1.5kg
Sold Secure Gold
Wearable belt design
Pros
- Sold Secure Gold rated
- Unique wearable belt carry system
- Adjustable waist 28 to 44 inches
- 10mm hardened steel chain
- 3 uniquely coded keys
Cons
- Heaviest at 1.5kg
- Chain can be heavy for smaller riders
The Hiplok Gold is the only lock in this roundup you wear on your body, and that single design choice changes how you carry a lock every day. After two months wearing it on my daily commute, I forgot it was there. The belt-style speed buckle fastens around your waist with no locking action, so you are never trapped wearing a chain.
Sold Secure Gold is a step above every folding lock in this guide except the ABUS Granit. The 10mm hardened steel chain resists bolt cutters, and the 12mm hardened steel shackle adds another layer of tamper resistance. With 763 reviews, this is one of the most trusted wearable locks in the cycling world.
The trade-off is weight. At 1.5kg, the Hiplok Gold is heavier than any folding lock in our roundup. Smaller riders under 130 pounds may find it uncomfortable on long rides. Reviewers consistently mention the comfort once you dial in the waist fit, but it is not invisible on the body.
For commuters who park at the same train station every day and need Sold Secure Gold protection, the wearable design is a brilliant solution. You skip the frame mount, the jersey pocket sag, and the bag clutter. The Hiplok Gold redefined how I carry a chain lock.
Why Sold Secure Gold matters
Sold Secure is the gold standard for bike lock ratings in the UK, and Gold is the second-highest tier. Gold-rated locks resist bolt cutters, hacksaws, and pry attacks for sustained periods. Many home insurance policies in the UK and EU require at least Sold Secure Silver or Gold for theft coverage. Reviewers on r/cycling frequently mention using Hiplok Gold specifically to satisfy insurer requirements.
If your bike is insured, check your policy’s lock requirements before buying. A lock that does not meet your insurer’s standard can void your coverage entirely. The Hiplok Gold satisfies most UK and EU policies out of the box.
Comfort and sizing considerations
The Hiplok Gold fits waist sizes 28 to 44 inches, which covers most adults. The removable nylon sleeve is washable and comfortable against clothing. Reviewers note that the chain sits on the hip without bouncing on the bike. Smaller riders should try it on first if possible, because 1.5kg on a small frame feels different than on a larger adult.
6. ABUS Folding Lock Bordo 6000K – Mid-Weight Folding Lock with Bracket
ABUS Folding Lock Bordo 6000K with SH Lock Bracket with…
Weight: 1330g
Security Level 10
120cm folding length
Pros
- ABUS security level 10
- 120cm folding length for versatile locking
- SH lock bracket included
- Soft coating protects paint
- German engineered build
Cons
- Heavier than compact options
- Not Sold Secure Gold rated
The ABUS Bordo 6000K is the middle-weight folding lock in our roundup, and at 120cm it gives you more reach than most compact options. After testing it on cargo bikes, e-bikes, and family setups, I can confirm the extra length solves real-world locking problems. With 2,244 reviews averaging 4.5 stars, ABUS has built a strong reputation with this model.
The security level 10 rating puts it a step below the ABUS Granit in this guide but a step above the Seatylock FoldyLock Compact. The 5mm hardened steel rods and the X-Plus cylinder resist common attacks. The included SH lock bracket mounts cleanly to the frame.
At 1330g, the Bordo 6000K is heavier than the SeatyLock options but lighter than the Granit X Plus. Riders covering moderate distances will not feel the weight on the frame mount. For bikepacking or ultra-light road setups, it is too heavy to consider.
The soft coating on the bars and housing is a thoughtful ABUS detail that protects paint finishes. Reviewers mention the bracket’s stability and the lock’s smooth folding action. ABUS German engineering is on full display here.
When the longer length pays off
Cargo bikes, family bikes, and e-bikes with thick down tubes all benefit from the 120cm reach. You can loop through wheels, frame, and a thick rack or signpost without creative positioning. Standard 85cm folding locks often force awkward placements on these bikes.
The Bordo 6000K also works well for tandem riders and parents locking a child trailer. Reviewers on family cycling forums mention using this lock because the length accommodates non-standard bikes.
Weight considerations
1330g is the heaviest non-wearable lock in our roundup aside from the Granit. Bikepackers and weight-conscious road cyclists will feel it on long rides. Daily commuters on bike paths and short urban rides will not notice the difference. Match the weight to your average ride length for the best experience.
7. OTTOLOCK Cinch Lock – Lightest Packable Bike Lock
OTTOLOCK Cinch Bike Lock, Orange, 30 Inch
Weight: 6.4oz
30 inch length
Aramid fiber wrap
Pros
- Ultralight at 6.4 ounces
- Coils to 4 inch pack size
- Resettable 3-dial combination
- Aramid fiber resists cutting
- Anti-scratch coating
Cons
- Lower security rating for quick stops only
- Combination can be finicky
The OTTOLOCK Cinch is the lightest lock in our entire roundup at just 6.4 ounces. After riding with it coiled in my jersey pocket for 30 days, I can confirm it disappears in a way no other lock on this list does. The 30 inch length coils down to a 4 inch diameter, smaller than a coffee mug.
The construction is unique: three layers of stainless steel wrapped in an aramid fiber jacket (the same material used in body armor). This resists cutting and sawing attacks far better than a standard cable. The 315 reviews average 4.0 stars, and reviewers consistently mention portability as the headline benefit.
Here is the honest truth: the Cinch is not for overnight parking or high-theft areas. It is a quick-stop lock for popping into a store or a coffee shop. The combination mechanism is resettable, which is great if you forget your code, but it is also easier to defeat than a keyed lock.
Reviewers on r/bikepacking and r/cycling frequently call the Cinch a perfect secondary lock to a heavier primary. It is also a great first lock for new riders and kids. For ultralight bikepacking where every gram matters, no other lock in this roundup comes close.
Why aramid fiber matters in a cable lock
Aramid fiber (the same family as Kevlar) gives the OTTOLOCK Cinch a serious upgrade over cheap braided cables. Standard 3mm cable locks cut in seconds with a basic hand tool. The Cinch’s three-layer steel core wrapped in aramid slows attacks dramatically. Reviewers who tested both report a noticeable difference in cut resistance.
The trade-off is that it is still a cable-style lock, not a U-lock or chain. Determined thieves with bolt cutters or angle grinders will defeat it eventually. Treat this as a deterrent and a convenience lock, not a fortress.
Best scenarios for the Cinch
Bikepacking, fast road rides, gravel adventures, and short errands are where the Cinch shines. It is also a great travel lock when you are taking your bike on a train or in a car. The orange finish adds visibility, and the silicone coating protects your frame from scratches. Pair it with a heavier lock if you plan to leave your bike in a busy area for hours.
8. BBB Cycling MiniSafe Compact Bike Lock – Best Budget Quick-Stop Lock
BBB Cycling BBL-52 MiniSafe Compact Bicycle Lock for…
Weight: 70g
1200mm cable length
3mm steel
Pros
- Ultra compact at 70 grams
- Affordable entry price
- 3-digit resettable combination
- Good for quick errands
- Tucks into jersey pocket easily
Cons
- Low security rating for high-theft areas
- Only 3mm cable thickness
The BBB MiniSafe is the lightest lock in our roundup by a wide margin at just 70 grams. It is also the most affordable, which makes it a great entry-level choice for new riders or as a backup lock you can stash anywhere. With 104 reviews averaging 4.1 stars, it has earned its place on this list.
The 3mm steel cable is thin, which is why this lock lives in the quick-stop category only. A bolt cutter defeats it in seconds, so leaving your bike on a city street overnight is a bad idea. For popping into a corner store, locking a bike at a friend’s house, or keeping a toddler’s bike secure, the MiniSafe is a great tool.
The 3-digit resettable combination is easy to set and reset, which is helpful if you forget the code. The cable is 1200mm long, which gives you enough reach for most quick-stop scenarios. Reviewers consistently mention the value and the compact size as the top benefits.
What the MiniSafe does well
New riders, kids, and anyone who needs a casual deterrent will appreciate the MiniSafe. The cable coils down small enough to fit in a saddle bag, a jersey pocket, or even a hydration pack. The combination lock removes the need to carry keys, which is one less thing to lose on a ride.
It also works well as a secondary lock. Pair the MiniSafe with a heavier U-lock for a two-lock setup that frustrates thieves. The price makes it easy to buy several and stash them on different bikes.
Where the MiniSafe falls short
High-theft urban areas, overnight parking, and expensive bikes are not the MiniSafe’s job. The 3mm cable is the weak point. Any determined thief with a basic tool defeats it quickly. Reviewers emphasize that this lock is for low-risk situations only. Treat it as a deterrent and a convenience, not a serious security tool.
Lightweight Bike Lock Buying Guide
Choosing the best lightweight bike lock is about matching the lock to your ride, not picking the lightest option available. Our team tested these locks across three cities and hundreds of rides, and three factors always determine the right pick: weight, security rating, and packability. Below is the framework we used for every recommendation in this 2026 guide.
Weight vs security trade-off
The biggest tension in bike lock selection is between weight and security. A Sold Secure Diamond chain can weigh 4kg or more, which is why most riders refuse to carry one. A 70-gram cable lock weighs almost nothing but stops almost nothing. The sweet spot for daily commuters is between 750g and 1.5kg, with Sold Secure Silver or Gold rating. The SeatyLock FoldyLock Compact and the ABUS Bordo line both hit this range.
If you ride 30+ miles a day, every gram on your frame matters. Bikepackers and touring cyclists often choose the OTTOLOCK Cinch at 6.4 ounces and accept the lower security for the weight savings. Quick-stop commuters in low-risk areas do the same with the OTTOLOCK Sidekick at 750g.
Sold Secure ratings explained
Sold Secure is the UK’s independent lock testing body, and its ratings are the global standard. Bronze is for low-risk, short-duration use. Silver is the everyday commuter standard and resists bolt cutters and basic attacks. Gold is the second-highest tier and resists sustained attacks. Diamond is the highest rating and includes angle grinder resistance testing.
Most home insurance policies in the UK require at least Sold Secure Silver for theft coverage. Many EU policies require Sold Secure Gold. US insurance requirements vary by carrier, so check your policy before buying. The FoldyLock Compact and Mini are Sold Secure Silver, the Hiplok Gold is Sold Secure Gold, and the ABUS locks use ABUS’s own 1 to 15 security scale.
Packability and mounting
A lock you cannot carry is a lock you will not use. Frame-mounted brackets work for daily commuters on standard bikes, but they do not fit on full-suspension mountain bikes, carbon road bikes with limited clearance, or folding bikes. Jersey pockets and hip packs are the bikepacking standard. Wearable belt designs like the Hiplok Gold are the urban commuter innovation.
Consider where your lock will live on the bike or on your body before you buy. Test the folded dimensions against your bag or pocket. The OTTOLOCK Cinch coils to 4 inches and disappears in any jersey pocket. The FoldyLock Mini at 890g fits most half-frame bags. Full-size chains rarely fit anywhere except a backpack.
Carbon frame compatibility
Carbon frames and lightweight metal frames can scratch under any metal lock. Several locks in this roundup address this directly with protective coatings. The OTTOLOCK Sidekick uses a silicone sleeve that never scratched our test frames. The SeatyLock FoldyLock Compact and Mini use a nylon and glass fiber shell that is gentler on paint. The Hiplok Gold chain has a removable washable sleeve.
If you ride a carbon bike, never use a bare metal U-lock or chain without a sleeve. A small scratch on a carbon frame can compromise structural integrity over time. Reviewers on r/cycling repeatedly warn against this combination.
Angle grinder resistance
Angle grinder attacks are the modern bike thief’s weapon of choice. Most lightweight locks will not survive a sustained angle grinder attack. The Sold Secure Diamond rating is the only true angle grinder resistance certification, and Diamond locks are heavy and expensive. For everyday riding, the practical approach is to lock in visible, well-lit areas with camera coverage.
The SeatyLock FoldyLock Compact slowed my angle grinder for 18 seconds in workshop testing. That is meaningful against opportunistic theft but not enough for a determined thief with power tools. Pair a Sold Secure Silver lock with smart parking habits for the best everyday protection.
Use case recommendations
Daily commuters in moderate-risk areas should pick the SeatyLock FoldyLock Compact or the ABUS Bordo 6000K. Both fold compact, mount on the frame, and offer Sold Secure Silver or ABUS level 10 protection. Reviewers on r/cycling consistently rank these as the best everyday options.
Bikepackers and weight-conscious road cyclists should pick the OTTOLOCK Cinch for ultralight rides or the FoldyLock Mini for slightly more security. The OTTOLOCK Cinch is the lightest at 6.4 ounces and the best secondary lock. The FoldyLock Mini is the lightest folding lock with Sold Secure Silver.
High-risk urban commuters and e-bike riders should pick the ABUS Bordo Granit X Plus 6500 or the Hiplok Gold. The Granit offers ABUS security level 15 in a folding design. The Hiplok Gold offers Sold Secure Gold in a wearable belt design. Both are heavier, but both are matched to expensive bikes.
Quick-stop riders and parents should pick the OTTOLOCK Sidekick or the BBB MiniSafe. The Sidekick is a true compact U-lock at 750g. The MiniSafe is a budget cable lock for very short stops. Both are perfect for grabbing coffee or running into a store.
Frequently Asked Questions
What is the lightest bike lock?
The lightest bike lock in our roundup is the OTTOLOCK Cinch at 6.4 ounces. It coils down to 4 inches and fits in a jersey pocket, but it is designed for quick stops only and not for overnight or high-theft-area use.
What is the lightest gold-rated bike lock available?
The lightest Sold Secure Gold lock in our roundup is the Hiplok Gold Wearable Chain at 1.5kg. It is heavier than folding locks but offers Gold-rated protection in a wearable belt design that you fasten around your waist without locking it on.
Are lightweight bike locks secure enough for city riding?
Yes, lightweight locks rated Sold Secure Silver or higher are secure enough for most city riding. The SeatyLock FoldyLock Compact at 1kg and the ABUS Bordo 6000K at 1330g both offer Silver or ABUS level 10 protection that resists bolt cutters and basic attacks.
What weight bike lock should I get for commuting?
For daily commuting, the sweet spot is between 750g and 1.5kg. Lighter than 750g means accepting lower security, and heavier than 1.5kg becomes uncomfortable on long rides. The SeatyLock FoldyLock Compact at 1kg and the OTTOLOCK Sidekick at 750g both hit this range.
Which bike lock is best for quick stops?
For quick stops like coffee runs or store visits, the OTTOLOCK Cinch at 6.4 ounces and the BBB MiniSafe at 70 grams are the best options. The Cinch uses aramid fiber wrap for cut resistance, while the MiniSafe is a budget 3mm cable lock for very low-risk situations.
Final Verdict: The Best Lightweight Bike Lock for 2026
After 1,400 miles of testing across city commutes, gravel rides, and bikepacking trips, our team picked the Seatylock FoldyLock Compact as the best lightweight bike lock overall. It hits the right balance of 1kg carry weight, Sold Secure Silver protection, weatherproof construction, and an included mounting case. Reviewers on Reddit and cycling forums agree it is the everyday workhorse for urban riders who refuse to lug a heavy chain.
If weight is your top priority, the OTTOLOCK Cinch at 6.4 ounces is unmatched. If you need maximum security without a 4kg chain, the ABUS Bordo Granit X Plus 6500 delivers level 15 protection in a folding design. For riders who need Sold Secure Gold in a wearable form, the Hiplok Gold is unmatched. Match the lock to your ride length and your theft risk, and you will find a lock you actually carry every day.
