Kryptonite Evolution Mini-7 U-Lock

Best for: Any commuter who leaves the bike anywhere
The gift that answers the thing a commuter actually worries about, and the one that needs no information about their bike at all.
- 13mm steel shackle (listing)
- 4 ft cable included (listing)
- U-lock, Mini-7 (model name)
- Key operated
- Listing prints no Kryptonite security rating
On the lock roundup this ranks first on published steel diameter, and for a commuter it is the clearest gift on this page because of what a commute is: the bike spends hours parked in public, on a schedule a thief can learn. The US Department of Justice guide to bicycle theft is the source behind our whole lock cluster, and the thing it makes clear is that predictability is the commuter’s specific exposure.
Good
- Fits any bike — there is no size, no standard and no compatibility question, which is what makes it the safest gift here
- A 13 mm hardened steel shackle is a published figure, and the only number on this page that resists a tool rather than announcing itself
- The included 4 ft cable reaches a front wheel, which is the component most commuters lose first
- Almost every commuter owns a lock they privately know is not good enough, and almost none of them upgrades it voluntarily
Less good
- A Mini-7 shackle is deliberately short, so it will not reach around a wide lamp post or a fat rack
- Heavy — this is a lock that lives in a pannier, not a pocket
- Kryptonite's security rating is a Kryptonite scale that does not convert to ABUS's, as our lock roundup explains at length
- No lock defeats an angle grinder, and the US DOJ's bicycle theft guide lists cutting tools among the standard attacks
Skip it if: They lock up indoors at both ends of the commute, or their bike lives in a secure bike room at work. The one thing to check: look at the lock already on their bike. If it is a thin cable or a combination lock, this is the gift. If it is already a thick U-lock, move down the page.
