A cordless angle grinder is how scooters get stolen now, and it does not care what you paid for your lock. Against a standard hardened U-lock, one cuts clean through in under a minute. Against a lock built to fight it, the Sold Secure Diamond Hiplok D1000, independent testers needed roughly five minutes and several cutting discs to get through a single side. That gap, seconds versus minutes by security tier, is the whole game when you lock an electric scooter to a public rack.
Scooters change the math a little. You haul the lock around more than you would on an e-bike, and a scooter’s slim stem or folded frame needs a lock shaped to loop it and still reach a rack. So we weighed portability against the two things that actually stop a theft: an independent Sold Secure rating and real grinder resistance. For a heavier ride, our best e-bike locks guide covers the same ground. Prices were checked on Amazon on July 17, 2026, and they move around, so confirm the live listing.

Hiplok D1000: best angle grinder resistance
The angle grinder is why so many high-security locks fail on a real street, and the D1000 is Hiplok’s answer to it. A graphene composite coating grabs a spinning cutting disc and chews it up instead of letting it slice through, so a thief burns discs and minutes rather than getting a quick cut. Independent testers needed roughly five minutes and multiple discs to breach one side, and it carries a Sold Secure Diamond rating. Hiplok even lists scooters and e-scooters on the box, so the shackle clears a stem or folded frame. The catches are real. It is heavy, and at around $330 it costs more than some scooters. For a premium ride that parks outside in a city, that math is easy.
Kryptonite Fahgettaboudit Mini: best hardened U-lock
New York bike messengers made this lock famous, and it is still one of the toughest U-locks you can buy against hand tools. The 18mm hardened shackle shrugs off bolt cutters and carries Kryptonite’s max 10/10 rating with a Sold Secure Gold grade behind it. The mini shape is a feature here. Less open space inside the U means less room for a thief to wedge a jack or pry bar, and a scooter stem is slim enough to fit without wasting the window. The tradeoff is that same small opening, which forces you to lock close to a slim rack or post. It is heavy for its size, but owners say it is the lock that lets them sleep. Against a determined grinder it falls faster than the D1000, so know your parking spot.
ABUS Granit X-Plus 540: best all-rounder
Reviewers have named the Granit X-Plus 540 the best all-round U-lock every year since 2015, and it is the one most scooter commuters should actually buy. It holds a Sold Secure Diamond rating and ABUS’s own max level 15, yet at about 3.2 pounds it is the lightest high-security U-lock in the standard size, which matters when you are the one carrying it. The keyway resists picking, the cylinder turns smooth, and the shackle is roomy enough to catch a stem and a real rack without a fight. It will not stall a grinder the way the Hiplok does, and no U-lock at this weight will. What it nails is the balance of security, daily usability, and price, which is exactly what most riders want.
Seatylock FoldyLock Compact: best folding lock for scooter carry
Folding locks trade some raw security for packability, and that trade is exactly right for a scooter you carry everywhere. The Sold Secure Silver FoldyLock Compact leads the breed on security per pound. At 2.2 pounds it clicks into a frame-mounted case, so it rides on the scooter instead of in your bag, then unfolds to a 33.5-inch loop that reaches racks a stubby U-lock cannot. That reach is the point on a scooter, where the anchor is often a fat post or an awkward railing. It is not the lock for an overnight park in a rough spot, so run it as your primary for quick daytime stops or as a second lock paired with a U-lock. For riders who want to carry light above all, this is the pick.
Kryptonite Evolution Mini-7: best value commuter
The Evolution Mini-7 hits the commuter sweet spot: a 13mm double-deadbolt shackle, a Sold Secure Gold grade, and about three pounds to carry. The bundled 4-foot cable loops through a scooter wheel or the folded deck, so one purchase covers the whole ride, not just the frame. For a rider in a low to medium theft area who wants solid protection without the weight or price of the top tier, this is the best value on the list. It is a hand-tool lock, not a grinder lock, so treat it as everyday security rather than overnight-in-a-hotspot security. With more than 14,000 reviews behind it, it is also the proven default that has anchored city bikes for years.
Kryptonite NY Fahgettaboudit 1415 Chain: best for e-motos and thick frames
For a seated e-moto, a moped, or a heavy scooter, a chain beats a U-lock because it wraps a thick frame and reaches an anchor a rigid shackle cannot. The 1415 runs 14mm hardened steel links, carries a Sold Secure Diamond rating, and sits well beyond what bolt cutters can touch. It also drapes around a fat wheel and through a real rack in one pass, which a mini U-lock will never do. The catch is weight. This thing is brutal to carry, so treat it as the lock that lives at your regular parking spot rather than one you haul on every trip. For the fast, heavy end of the scooter world, it is the right tool.
What Sold Secure tiers actually buy you
Sold Secure is an independent body that attack-tests locks with real tools and grades them Bronze, Silver, Gold, and Diamond. Higher grades survive longer against tougher tools, and the ladder is the closest thing to an honest label on a lock box. Here is how we read those tiers against the tool that matters most, a cheap cordless angle grinder.
Silver is a sensible floor for a scooter in low-risk spots and short daytime stops. It stops opportunist hand tools and buys real time, which is why the folding FoldyLock earns its place. Gold is the commuter standard, tough against bolt cutters and pry bars, the grade the Fahgettaboudit Mini and the Evolution Mini-7 carry. Diamond is the top tier, and the ABUS 540 and the 1415 chain hold it. Here is the honest catch. A Diamond rating measures tool resistance, but only the Hiplok D1000’s grinder-specific build meaningfully slows an angle grinder. Every other lock here, Diamond or not, is a hardened-steel lock that a grinder cuts in under a minute. Rate the tier for the hand-tool threat, then treat the grinder as a separate problem you solve with parking choice or the D1000.
How to lock an electric scooter
The best lock in the world does nothing if you loop it around the wrong part. Pass the lock through the scooter’s stem or frame, not just a wheel or the handlebar grip, and around a solid, immovable rack or post. Pick an anchor a thief cannot lift the scooter over or unbolt. Keep the lock high off the ground so nobody can smash it against the pavement, and fill the empty space inside a U-lock so there is no room to lever it. On a folding scooter, folding the deck first tightens the loop and leaves even less slack to attack. For the full walkthrough with photos, see our guide on how to lock a scooter.
How to choose an electric scooter lock
Set a tier floor, not a marketing claim. Aim for Sold Secure Silver at the very least, Gold for daily commuting, and Diamond if the scooter is expensive or parks in a rough area. A lock that only advertises “maximum security” with no independent rating is telling you nothing.
Assume the thief has a grinder. Cheap cordless angle grinders have changed the game, and almost every hardened lock falls to one in under a minute. If your scooter lives in a high-theft area or sits out overnight, the grinder resistance the Hiplok D1000 offers is worth paying for. Everywhere else, a Gold-rated lock buys enough time to make a thief move on.
Weigh the weight, because you carry it. On a scooter you lug the lock more than on an e-bike, and security and weight climb together. Be honest about whether you will carry four pounds of U-lock every day or would actually reach for a 2.2-pound folding lock, since the lock you bring beats the stronger one left at home.
Check the shape against your scooter. A mini U-lock is compact and hard to lever but needs a slim rack close by. A folding lock reaches farther for awkward anchors. A chain wraps thick frames and fat wheels. Match the lock’s shape to the racks you actually use.
Spend a fraction of the scooter’s value. A rough rule puts about 10 percent of the ride’s price toward the lock. On a $1,500 scooter, a $100 to $180 lock is not overkill, it is insurance you buy once.
Electric scooter lock FAQ
Can any scooter lock stop an angle grinder?
No lock is truly grinder-proof, but some are grinder resistant. Locks like the Hiplok D1000 use a composite coating that stalls and gums up a cutting disc, so an attack takes several minutes and multiple discs instead of under a minute. Every standard hardened lock, U-lock or chain, falls to a grinder quickly, so grinder resistance is a specific feature you pay for, not something a high tier guarantees.
U-lock, folding lock, or chain for a scooter?
A hardened U-lock gives the most security for its weight and is hard to lever, but its small window needs a slim rack nearby. A folding lock is lighter and reaches farther, which suits a scooter you carry and awkward anchors, at the cost of some raw strength. A chain wraps thick e-moto frames and fat wheels but is heavy. Many riders carry a folding lock for quick stops and keep a chain or U-lock at their regular parking spot.
What does a Sold Secure rating mean?
Sold Secure is an independent body that attack-tests locks with real tools and grades them Bronze, Silver, Gold, or Diamond. Higher grades survive longer against tougher tools. For a scooter, Silver is a floor for low-risk stops, Gold is the commuter standard, and Diamond is the top tier for valuable rides or rough areas.
Do disc locks and alarms help on a scooter?
They help as a layer, not a primary lock. An alarmed disc lock or a motion alarm adds noise and hassle that makes a grab riskier, but it does not anchor the scooter to anything fixed. Use one alongside a Sold Secure lock that ties the frame to a rack, never instead of it.
Should I use two locks?
For long or overnight parking in a city, yes. Two different lock types, such as a grinder-resistant U-lock plus a hardened chain or folding lock, force a thief to carry and use more tools. That raises the time and risk enough that most walk away and look for an easier target.
A good lock is step one, but adding an alarm or a GPS tracker makes recovery far more likely. See our best e-bike locks guide for heavier rides, learn how to lock a scooter the right way, and browse all our locks and security guides to build a full anti-theft setup.
