A good lock won’t make a bike impossible to steal, but it makes your bike a slower, noisier target than the one parked next to it. These are the locks that stand out for security, price and everyday use in 2026.
We haven’t tested these locks ourselves. Our picks are based on lock type, steel thickness, maker specs, independent rating schemes and buyer ratings.

How We Picked
We started with lock type. Bike-theft advice, such as Sheldon Brown’s well-known lock strategy guide, favors hardened U-locks and heavy chains over cables, because cables can be cut quickly with hand tools. Then we looked at shackle or link thickness, maker security ratings, and buyer ratings with thousands of reviews behind them.
If you want an independent check, the UK testing body Sold Secure grades bike locks Bronze, Silver, Gold and Diamond. You can look up a specific model in the Sold Secure bicycle database before you buy.
1. Kryptonite Evolution Mini-7: Best Overall
- BUILT TO LAST: The Kryptonite Evolution Mini‑7 U‑Lock is constructed with a 13mm hardened Max‑Performance steel shackle to help resist cutting and leverage attacks, while a durable vinyl‑coated protective sleeve prevents scratches to your bike’s frame and preserves its finish.
- DOUBLE-DEADBOLT DESIGN: Locks the shackle on both sides of the crossbar for enhanced resistance against twisting and pulling. Certified by Sold Secure Gold, it also includes a high‑security disc‑style cylinder to resist picking and drilling
- VERSATILE SECURITY WITH 4‑FT CABLE: Includes a 4‑ft (120 cm) double‑loop security cable ideal for securing your front wheel, helmet, or accessories. Together with the U‑lock, it is perfect for securing bicycles and e‑bikes at work, school, or around town
- COMPACT, COMMUTER-FRIENDLY SIZE: This U-lock features interior locking dimensions of 3.25” x 7” (8.3cm x 17.8cm) and a total lock weight of 3.55 lbs (1.61 kg), providing a tight fit around bike racks to deter leverage attacks. Weather-treated components help protect against rust and outdoor exposure for reliable everyday use
- EASY MOUNTING BRACKET INCLUDED: Comes with a secure FlexFrame‑U bracket that attaches directly to your bike frame for hassle‑free transport—allowing you to carry the lock easily with no backpack or lock bag required
The Evolution Mini-7 is the lock most riders should start with. It’s a compact U-lock with a 13mm hardened steel shackle and a 4-foot flex cable for the front wheel. At around $105 with a 4.5-star average from more than 14,000 ratings, it has one of the strongest track records of any lock on Amazon.
The small shackle has two benefits: it’s lighter to carry, and it leaves less space for a thief to fit a jack or lever. The trade-off is that it won’t fit around thick posts or trees.
2. Kryptonite New York Fahgettaboudit Mini: Best for High-Theft Areas
- HIGH-SECURITY DESIGN: Made from a 18mm hardened max-performance steel shackle, this bike lock provides ultimate resistance against cutting and leverage attacks
- PATENTED LOCKING SYSTEM: Features a patented hardened double deadbolt design that gives additional protection against twist attacks, plus a patented steel sleeve over crossbar for double security and a high-security disc-style cylinder, resistant to picking and drilling
- MULTI-FUNCTIONAL: This Kryptonite bike lock is ideal to secure your bicycles, sports equipment, gates and fences, tool boxes & ladders, grills & lawnmowers, skateboards, truck bed and more
- DESIGNED FOR E-BIKE: U-Lock Interior Locking Dimensions; 3.25" x 6". Exterior Dimensions; 9.5" x 6" x 2", 18mm steel shackle with a weight of 4.55 lbs. Includes three keys and rated 10/10 for ultimate security on our scale.
- ATPO & KEYSAFE PROGRAM ELIGIBLE: Register to qualify for Kryptonite's Anti-Theft Protection Offer and KeySafe key replacement service
If you park in a big city or leave your bike for long periods, step up to the Fahgettaboudit Mini. It has a much thicker 18mm shackle and is one of Kryptonite’s heaviest-duty U-locks. It costs around $180 and holds a 4.6-star average from about 3,500 ratings.
It weighs considerably more than the Evolution Mini-7, so it’s best for a bike you lock in the same place every day.
3. Kryptonite New York Fahgettaboudit Chain 1410: Best Chain
- The ultimate chain lock for high theft areas
- 14 Millimetre six-sided hexagonal chain links made of triple heat-treated boron manganese for the ultimate strength in a chain
- Narrow inner width of individual links defends against leverage attacks
- Includes maximum security New York disc lock with 15 mm ovalised hardened steel shackle
- Hardened steel sleeve over crossbar for double security. Product weight: 15.25 pounds
A chain wraps around things a U-lock can’t, like thick poles, fences or railings. This 14mm chain comes with a matching disc padlock and costs around $145.
The catch is weight. A chain this thick is heavy, so many owners leave it at the place they lock up most often instead of carrying it.
4. Hiplok D1000: Best for Expensive E-Bikes
- RESISTS ANGLE GRINDER ATTACKS World's first portable anti-angle grinder bike lock. Proven to withstand severe and sustained angle grinder attacks. D Lock independently tested to Sold Secure Diamond & ART 4 Star ratings.

- SUITABLE FOR ALL RIDE TYPES High security for scooter, e-scooter, bicycle, e-bike, cargo bike, and motorcycle. Compatible with Hiplok X Chain, Mega Chain, and anchors A1000, AX1000, ANKR for complete security ecosystem.
- VERSATILE CARRY OPTIONS AVAILABLE Designed for portability at 1.93kg. Pair with optional Carry Pouch for bicycle mounting or belt use, BR1000 for frame pannier mounting, or Lock Sleeve for bag protection.
Battery-powered angle grinders can cut through most steel locks. The Hiplok D1000 is built to resist that kind of attack, using a shackle made of a special composite material designed to wear down cutting discs. At around $330 it costs more than many bikes, so it makes sense mainly for e-bikes and high-end bikes.
5. ABUS Bordo 6000K: Best Folding Lock
- Safe and flexible: Foldable bicycle lock with ABUS security level 10, good protection to safeguard against medium theft risk
- Solid: 5 mm thick rods and housing made of specially hardened steel The rods are connected by special rivets
- Product details: Bordo Big 6000K/120, length 120 cm (when unfolded), width 80 mm, weight 1546 g, colour black, includes 2 keys and bracket
- Coating: Folding lock with extra soft and resistant coating on the bars and housing to protect against paintwork damage and provide a good grip
Folding locks use hardened steel plates joined by rivets. They fold into a small block that mounts on the frame, so they’re easier to carry than a chain while offering more reach than a mini U-lock. The Bordo 6000K costs around $115.
6. Kryptonite KryptoLok Standard: Best Value U-Lock
- BUILT TO LAST: The Kryptonite Kryptolok Standard U‑Lock is constructed with a 12.7mm hardened performance steel shackle to help resist cutting and leverage attacks, while a durable vinyl‑coated protective sleeve prevents scratches to your bike’s frame and preserves its finish
- DOUBLE-DEADBOLT DESIGN: Locks the shackle on both sides of the crossbar for enhanced holding power and resistance against twisting and pulling. Certified by Sold Secure Silver, it also includes a high‑security disc‑style cylinder to resist picking and drilling
- VERSATILE SECURITY WITH 4‑FT CABLE: Includes a heavy-duty 10mm x 4‑ft (120 cm) double‑loop security cable ideal for securing your front wheel, helmet, or accessories. Together with the U‑lock, it is perfect for securing bicycles and e‑bikes at work, school, or around town
- STANDARD, COMMUTER-FRIENDLY SIZE: This U-lock features interior locking dimensions of 4” x 9” (10.2cm x 22.9cm) and a total lock weight of approximately 3.65 lbs (1.66 kg), providing a versatile locking reach for thicker poles and racks. Weather-reated components help protect against rust and outdoor exposure for reliable everyday use
- EASY MOUNTING BRACKET INCLUDED: Comes with a secure FlexFrame‑U bracket that attaches directly to your bike frame for hassle‑free transport—allowing you to carry the lock easily with no backpack or lock bag required
The KryptoLok Standard is a full-size U-lock with a 12.7mm shackle, priced around $80, with a 4.6-star average from about 6,000 ratings. It has a larger opening than the Mini-7, so it fits around more objects. That also means more room for a leverage attack, so it suits lower-risk areas better.
7. Master Lock 8385D: Best Budget Pick

FAQ
What is the most secure type of bike lock?
Thick hardened U-locks and heavy chains are the most secure common types. Angle-grinder-resistant locks like the Hiplok D1000 go further, but they cost much more.
Are cable locks safe enough on their own?
No. Cable locks can be cut quickly with hand tools. Use them only to secure wheels or a seat alongside a U-lock or chain.
How much should I spend on a bike lock?
A common rule is to spend about 10% of your bike’s value, more if you park in a high-theft area.
Should I use two locks?
Yes, if you can. Two different lock types, like a U-lock and a chain, force a thief to carry two kinds of tools.
