Kryptonite New York Fahgettaboudit Mini U-Lock

This is the lock to buy when the bike costs more than the rent. The Fahgettaboudit Mini uses an 18 mm hardened steel shackle with a double-deadbolt crossbar, which puts it in the small group of locks that shrug off bolt cutters and force attackers to use a grinder and time. The mini shackle is deliberately small so there is little room to fit a jack or pry bar. The trade-off is that small opening: you will not lock both frame and wheel to a fat pole with it, and it is heavy enough that many owners leave it at the office rack and carry something lighter for quick stops.

Hiplok D1000 Angle Grinder Resistant U-Lock

The D1000 exists because angle grinders became the default theft tool for e-bikes. Hiplok bonded a ceramic composite material to the shackle that eats cutting discs, so instead of ten seconds and one disc, a thief needs multiple discs and minutes of noise. It is compact, heavy, and expensive, which is exactly the recipe for a lock that stays at your highest-risk parking spot. The shackle opening is small, similar to the Fahgettaboudit Mini, so it secures the frame and rear wheel to a slim post at best. If your e-bike lives locked outside in an area with grinder theft, this is the category to shop.

Best for: Premium e-bikes locked in high-theft urban areas · Riders who have already lost a bike to a grinder · Fixed-location daily parking

ABUS Granit XPlus 540 U-Lock

ABUS's Granit XPlus 540 is a favorite among shop mechanics because it hits a sweet spot: a 13 mm square-profile shackle that is tougher than its diameter suggests, a lock body that is noticeably lighter than 18 mm monsters, and an XPlus disc cylinder that resists picking well. It comes in a couple of shackle lengths, and the longer one is handy for e-bikes with fat downtubes and wide racks. ABUS includes a frame bracket. It is one of the highest-rated locks in its weight class, making it a solid pick for commuters who want better-than-average protection without carrying a dumbbell.

Best for: Commuters who park in mixed-risk areas · Riders who dislike the weight of 18 mm locks · E-bikes with wide tubes that need a longer shackle

Apple AirTag (with hidden bike mount)

An AirTag is not a GPS tracker — it relies on nearby iPhones to report its location through the Find My network — but in a populated area like the Dallas suburbs that network is dense enough to locate a stolen e-bike surprisingly often. The trick is hiding it: under the saddle in a purpose-made mount, inside a bell-shaped mount, in a reflector housing or under a bottle cage. Thieves know to look, so pick a mount that is not obvious. Battery life is about a year on a coin cell. Android users should look at Tile or a Google Find My Device tracker instead.
