Kryptonite Evolution vs New York

Two steps on the same ladder: a 13mm Sold Secure Gold mini, and a 16mm heavy-duty standard. The question is not which is stronger - it is whether your bike sleeps outdoors.

By Stephen V.Last updated How we pick

Buy the Evolution Mini-7 unless your bike sleeps outside. That is the whole decision, and the shackle diameter is a proxy for it rather than the point. These two locks sit on the same ladder: the Evolution Mini-7 publishes a 13 mm hardened shackleand — the figure that matters most — a Sold Secure Gold certification, which is an independent grade rather than a number Kryptonite assigned itself. The New York Standard publishes a 16 mm shackle in a full-size body, described on its own listing as heavy duty for e-bikes and scooters, with a pick-resistant disc cylinder.

Three millimeters sounds like nothing. In practice it is the difference between a lock a thief with a bolt cutter cannot touch and must bring a grinder for, and a lock that makes the grinder job meaningfully longer. Both cost you something real: the New York is roughly double the price and distinctly more weight to carry twice a day, and the lock you leave at home because it is heavy provides no security at all. That trade — not the spec sheet — is what this page is about.

One thing to get straight before the comparison. Kryptonite publishes an in-house security score out of 10 on its locks, and that number is not comparable across brands, because each maker sets its own scale. Where an independent grade exists we lead with it: the Evolution Mini-7’s listing states Sold Secure Gold certification, and Sold Secure is a third-party test house whose Bronze / Silver / Gold / Diamond ladder involves actual attack testing. That is a different class of claim than a self-assigned 7 out of 10.

We have not attacked either lock. Nobody should trust a site that claims to have grinder-tested locks it bought online. Every figure below is read from a published listing on a dated visit, and where a listing publishes nothing — neither of these publishes a weight — the row says so instead of carrying a number we invented. Here is exactly what we do instead of testing.

Kryptonite Evolution Mini-7 U-Lock

The lock most commuters should actually own: a 13mm shackle that carries an independent Sold Secure Gold grade in a mini body, at roughly half the weight and half the money of the New York line — and it ships with the cable that solves the front wheel.

Strengths

  • Independently graded Sold Secure Gold, not just a maker's in-house number
  • 13mm hardened shackle and a double-deadbolt design, both on the listing
  • Mini body gives a crowbar or jack almost no room to work
  • 4 ft KryptoFlex cable and a FlexFrame-U bracket are in the box

Trade-offs

  • 13mm is a shorter grinder job than the 16-18mm locks — this is not an overnight-outdoors lock
  • The mini opening is genuinely restrictive; it will not reach a fat post plus a wheel
  • The bundled cable is convenience security only and cuts in seconds
  • Listing publishes no weight, so plan the carry by its class rather than a figure

What 13 mm versus 16 mm buys you

Thieves use three attacks, and the shackle diameter matters for a different amount in each.

Bolt cutters and hand tools: both locks are out of reach. A 13 mm hardened shackle is already past what a portable bolt cutter will close on, which is the dividing line between a real lock and a deterrent. If your current lock is a cable or a thin U-lock, moving to either of these is the big upgrade, and the step from 13 to 16 is the small one.

Leverage — crowbars, car jacks, pipes: here the mini body wins, and it is the most underrated thing on this page. A leverage attack needs somewhere to insert the tool, and the Evolution Mini-7 is specifically shaped to deny it. A full-size New York Standard has a bigger opening by design, which is useful for locking to a fat post and is also room a thief can use. More steel, more space: the two effects partly cancel.

Angle grinders: neither lock stops one, and anybody who tells you otherwise is selling something. What diameter buys here is time— more seconds of noise, sparks and exposure for the thief, and that is exactly what 16 mm is for. If your bike is on a street overnight, that extra time is the product you are buying. If the bike is in a bike room or comes indoors, you are paying for seconds nobody will be there to use. We go through what “grinder-proof” actually means in the grinder-resistant lock guide, and the attack methods themselves in how thieves break bike locks.

The cost nobody puts on the box

Neither listing publishes a weight, which is irritating, because weight is the specification that decides whether a lock gets used. What we can say honestly: the New York Standard is in the same family as the 18 mm Fahgettaboudit Mini, whose weight runs around four and a half pounds, and the Evolution Mini-7 is roughly half that class. The practical consequences:

  • A mini U-lock fits in a bag or a jersey pocket. A full-size 16 mm lock wants a frame bracket or a pannier, and you will feel it on a hilly commute.
  • The mini costs you reach. This is the real downside and the one people discover at the rack: a mini opening may not pass around a fat signpost plus your frame plus a wheel. Check what you actually lock to before buying one, and read how to lock your bike for the geometry.
  • The heavier lock gets left at home. Which converts a 16 mm lock into a 0 mm lock. That is the single most common way a security upgrade fails, and it is why we do not recommend the heaviest lock to everyone.

Which one your situation calls for

Daytime parking, bike indoors at night: Evolution Mini-7.This is most commuters. The bike is at a rack for eight hours in daylight, with people around, and a Gold-graded 13 mm lock in a leverage-proof body is a serious obstacle for that window. Spend the difference on a second lock for the front wheel instead — two locks beat one bigger lock in most scenarios, as we argue in do you need two bike locks.

Bike left out overnight, or locked in a high-theft city: New York Standard. Overnight is a different threat model: no witnesses, unlimited time, and the thief can come back with the right tool. Here the extra diameter and the full-size opening (which lets you lock the frame and a wheel to something immovable) are worth the weight.

An e-bike: New York Standard, at minimum. The New York listing names e-bikes and scooters for a reason: the bike is worth more, it is too heavy to carry upstairs, so it spends more time locked outside, and the battery is a separate theft target. Our e-bike lock picks go further, and the battery problem has its own page in how to secure an e-bike battery.

A beater bike, or parking in a low-theft town: neither. Both of these are more lock than the situation needs, and a budget lock plus good habits is the right answer. How much to spend is genuinely a function of what your bike is worth and where it sits, which we work through in how much to spend on a bike lock.

Two things that are equal, and one that is not

Equal: the keys and the bracket. Both ship with three keys and a FlexFrame-U style mount, so neither is more annoying to live with day to day.

Equal: the cylinder story is not a differentiator. The New York listing names a pick-resistant disc cylinder; the Evolution listing names a double deadbolt, which is about how the shackle is held rather than how the lock is picked. Neither matters much in practice, because picking a decent U-lock is a skill with better uses, and real thieves cut.

Not equal: the Evolution includes a cable.A 4 ft KryptoFlex cable comes in the Mini-7 box, and it genuinely solves something — the front wheel — that the mini U-lock cannot reach. Be clear-eyed about what it is: a cable cuts in seconds, so it is there to make a wheel annoying to take, not to secure a bike. It is still the reason the Mini-7 covers more of a real bike than its opening suggests.

What we would not do

Compare the in-house scores.Kryptonite’s own 1-to-10 scale ranks its own locks and tells you nothing against another brand’s number. If you want to compare across brands, compare Sold Secure grades, which is the point of having an independent test house.

Buy the biggest lock as insurance. It is the most expensive way to end up locking your bike with nothing, because you left the heavy one at home. Match the lock to the parking.

Treat either as grinder-proof. Neither is. Lock to something immovable, in a visible spot, and read the theft-prevention habits— they are free, and they do more than three millimeters of steel.

Frequently asked questions

Is the Kryptonite Evolution strong enough for a city?

For daytime city parking, yes. The Evolution Mini-7's listing publishes a 13mm hardened shackle and Sold Secure Gold certification, which is an independent attack-test grade rather than a maker's in-house score. That combination is past what portable bolt cutters can defeat, and the mini body leaves a crowbar nowhere to sit. Where it runs out is overnight street parking: no lock in this class stops an angle grinder, and the thinner shackle buys fewer seconds. If the bike sleeps outside, step up to the 16mm New York or beyond.

What is the difference between Kryptonite Evolution and New York?

They are two tiers of the same ladder. The Evolution Mini-7 publishes a 13mm shackle with Sold Secure Gold certification, a double deadbolt and a 4ft cable in the box, in a compact mini body. The New York Standard publishes a 16mm shackle in a full-size body with a pick-resistant disc cylinder, and its own listing names e-bikes and scooters as the use case. In practice you are trading three millimeters of steel and a bigger opening against roughly double the price and distinctly more weight to carry every day.

Is a 16mm shackle worth it over 13mm?

It depends entirely on how long your bike is unattended. Against hand tools both are effectively immune, so the extra steel changes nothing. Against an angle grinder neither is immune, and what 16mm buys is more cutting time - more seconds of noise and sparks in public. That is valuable precisely when nobody is around to notice, which means overnight or in a quiet alley. For a bike parked in daylight at a busy rack, the thinner, lighter, cheaper lock is the better buy because it is the one you will actually carry.

Is a mini U-lock big enough?

It is big enough for the strongest way to lock a bike - frame and rear wheel to a rack - and that is why minis are recommended so often. The catch is reach: a mini opening can fail to pass around a fat signpost, a thick rack tube or a frame plus a wheel together, and you find that out standing at the rack. Look at what you lock to on your actual commute before you buy one. If your options are mostly chunky street furniture, the full-size body is worth the weight.

Does the Evolution Mini-7 cable count as security?

Only as convenience security. The 4ft KryptoFlex cable in the box exists so you can loop a front wheel that the mini U-lock cannot reach, and that is genuinely useful - wheels get taken. But a cable of that type cuts in seconds with hand tools, so it should never be the only thing holding your bike. Treat it as a way to make a quick-release wheel annoying rather than a second lock. If you want two real locks, a second U-lock or a chain is the answer.

Which Kryptonite lock should I buy for an e-bike?

Not the Evolution Mini-7 as your only lock. E-bikes are worth more, are too heavy to carry indoors casually, and therefore spend more time locked outside - which is exactly the threat model the 13mm class is weakest against. The New York Standard's own listing names e-bikes and scooters, and the 18mm Fahgettaboudit Mini is the tier above that. Whichever you pick, the battery is a separate theft target with its own answer, and locking the frame to something immovable matters more than the model you choose.

Can you compare Kryptonite's security rating to ABUS's?

No, and it is the most common mistake in lock shopping. Kryptonite scores its locks roughly 1 to 10 and ABUS roughly 1 to 15, each on a scale it set itself, so a Kryptonite 7 and an ABUS 10 are not measurements of the same thing. The only cross-brand comparison that means anything is an independent grade - Sold Secure's Bronze, Silver, Gold and Diamond ladder, which involves actual attack testing by a third party. If two locks both carry Gold, they are in the same band whatever the box says.
