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.

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.
Best for: High-value e-bikes locked outdoors · Urban and campus parking with theft pressure · Riders who leave the bike in one spot all day

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.

The Knog Scout does two jobs: it is a motion alarm that screams when the bike is moved, and it is an Apple Find My device so you can locate it like an AirTag. It bolts to the bottle-cage bosses with security screws and is controlled from the Knog app. The alarm is loud enough to make a thief reconsider a quick grab, and it arms and disarms automatically as your phone comes and goes. It is iPhone-only for the Find My function. Rechargeable via USB-C. It works best as a layer on top of a real lock, not a substitute.
Best for: iPhone users who want alarm plus location · Bikes parked briefly outside shops · Tamper deterrence
