A good e-bike lock must suit two things: the risk of theft at the parking location and your bike. A sturdy shackle is of little use if it does not reach around the frame and the bike rack. Conversely, a generous length is no substitute for tested security.
For this comparison, four models with different focuses are considered: ABUS GRANIT Super Extreme 2500, Hiplok DX1000, LITELOK X1, and ABUS BORDO GRANIT 6500K. The selection for 2026 is based on documented product features and test classes. It is not an independent break-in test or a ranking of the best lock for all scenarios.
| Model | Lock type | Documented Sold Secure test class | Internal dimensions or circumference | Weight according to product specifications | Main limitation |
|---|---|---|---|---|---|
| ABUS GRANIT Super Extreme 2500/165HB230 | U-lock | Pedal Cycle Diamond and Powered Cycle Diamond | 102 × 230 mm, width × height | 2,470 g | High weight and significant space required for transport |
| Hiplok DX1000 | U-lock | Powered Cycle Diamond | 112 × 205 mm, width × height | Approx. 2,600 g | Large and heavy for daily transport |
| LITELOK X1 | U-lock | Pedal Cycle Diamond and Powered Cycle Diamond | Approx. 101 × 196 mm, width × height | Approx. 1,700 g | Smaller shackle opening than the other two U-locks |
| ABUS BORDO GRANIT 6500K/90 | Folding lock | Pedal Cycle Gold | 90 cm circumference | 1,670 g | No equivalent test basis for angle grinder resistance compared to the three U-locks |
The information refers to the versions mentioned. The circumference of a folding lock cannot be compared directly to the rectangular internal opening of a U-lock. Also, check whether a transport mount is included with the chosen version.
Four e-bike locks compared
ABUS GRANIT Super Extreme 2500
The GRANIT Super Extreme 2500 is an option if you prioritize resistance to angle grinder attacks for your e-bike lock. ABUS uses a special material blend containing tungsten carbide for this purpose. The model is certified as both Sold Secure Pedal Cycle Diamond and Powered Cycle Diamond.
The version considered offers an internal opening of 102 mm in width and 230 mm in height. In this comparison, it is the longest of the three U-locks. This can help when locking up if the frame and the parking rack are a bit further apart. However, the width remains limited: A voluminous frame tube and a thick post combined may require too much space.
At 2,470 g, you should plan for its transport carefully. The version with the USH2500 mount allows it to be attached to the bike; whether there is enough room depends on the frame and any already installed accessories.
Our assessment: A suitable candidate for high security requirements, provided the opening and transport solution fit. Before purchasing, also check whether you can comfortably insert and remove the shackle at your usual parking spot.
Hiplok DX1000
The Hiplok DX1000 is aimed at larger bikes and e-bikes, among others. Its internal opening measures 112 × 205 mm, offering the largest internal width of the U-locks compared here. Sold Secure lists this model with the Powered Cycle Diamond test class.
The additional width can be helpful for thick frame tubes. However, this does not automatically guarantee a fit for cargo bikes or particularly wide e-bike frames. The deciding factor is the combination of the frame, the attachment point, and the angle at which you can position the lock.
The documented weight is approximately 2.6 kg. Those who carry it daily or frequently switch between several bikes should take this effort into account. The lock also requires corresponding space for storage in a bag.
Our assessment: Particularly interesting if the opening of a narrower U-lock is insufficient. For the purchasing decision, it is worth drawing the internal contour on paper and testing it on your own bike. In doing so, also consider the external dimensions and handling between neighboring bikes.
LITELOK X1
The LITELOK X1 combines composite armor designed to withstand angle grinder attacks with a weight of approximately 1.7 kg. It holds the Sold Secure Pedal Cycle Diamond and Powered Cycle Diamond test classes. Among the three U-locks in this selection, it is the lightest.
For commuters, this weight difference can be relevant in everyday life: the lock must be carried regularly and handled at the parking location. The internal opening is approximately 101 × 196 mm, making it slightly smaller than the GRANIT Super Extreme 2500 and the DX1000.
Whether this size is sufficient depends on your locking situation. If the frame is positioned directly next to a suitable bike rack, you need less reach than with a wide post. According to the manufacturer, the available X1 mounts are sold separately; check the actual scope of delivery.
Our assessment: An obvious candidate if you want to combine tested angle grinder resistance with a lower transport weight. However, the X1 remains a heavy piece of accessory and must be matched as carefully to the frame and parking rack as the larger models.
ABUS BORDO GRANIT 6500K
The BORDO GRANIT 6500K offers a different type of handling: its connected steel bars can be unfolded and wrapped around the frame and the attachment point. For the 90 cm version considered, ABUS specifies 1,670 g and the independent test class Sold Secure Pedal Cycle Gold.
The advantage lies primarily in its folded transport format and the movable joints. An SH mount is included with the corresponding version. However, the individual bars remain rigid. Therefore, a folding lock behaves differently when locking than a freely movable chain.
The safety level 15 specified by ABUS is part of the manufacturer's own rating system. It should not be equated with proof of the same resistance to angle grinders as the three U-locks.
Our assessment: An alternative if the folding format and locking options are particularly important to you. If there is an increased risk of targeted angle grinder attacks, we would prioritize the appropriately tested U-locks from this selection. Also, check the model name for the BORDO carefully: information for other 6500 versions cannot be applied automatically.
U-lock, chain, or folding lock: what suits your everyday life?
U-locks: Does the opening fit around the frame and parking rack?
A U-lock forms a fixed opening. For selection, its width and height are relevant, as well as the space required to position it. Especially with e-bikes, a thick down tube, an integrated battery, or an unusual frame shape can restrict the usable locking points.
Check the fit at your most frequent parking location if possible. The shackle should connect the frame to a solid object without pressing against cables or sensitive components. Do not just plan for the locked position: you must also be able to reach the lock mechanism and operate the key.
For the daily commute, a U-lock is particularly practical if you know of a reliable place to lock your bike. For constantly changing parking locations, its rigid shape can limit your options more frequently.
Chain locks: How much length and weight make sense?
A chain can be flexibly guided around objects of various shapes. This can be helpful when shopping or in front of changing buildings. Its length must be sufficient to cover the entire path around the frame and the attachment point; a small reserve makes handling easier.
With the same construction, more length simultaneously means more material and weight. For a fixed parking space, it may make sense to keep a suitable heavy chain there. For on-the-go use, you should check whether you can transport the entire lock comfortably and safely.
The deciding factor is the tested combination of chain and lock. A thick-looking sheath says little about the chain links underneath.
Properly categorizing folding, frame, and cable locks
Folding locks offer a compact pack size but require movement space for their bars when locking. A frame lock blocks a wheel; by itself, it does not prevent someone from carrying the bike away. A suitable extension chain can expand its function, provided the lock and chain are designed for this purpose.
Simple steel cable and spiral cable locks should not be the only security measure for a high-quality e-bike. A thin additional security device on the front wheel does not replace a heavy-duty main lock on the frame.
Compare bike locks based on their specific testing and locking options. Two locks can create additional obstacles if used sensibly; however, their security levels cannot be added together mathematically.
Which security features are truly meaningful?
Distinguishing between manufacturer levels and independent test marks
A number on the packaging is only understandable within its associated system. A manufacturer's level cannot be easily compared to a similarly high number from another brand. Therefore, also pay attention to independent tests for the specific model.
With Sold Secure, the test class and product category belong together. Within each category, Diamond ranks above Gold, Silver, and Bronze. However, the Pedal Cycle and Powered Cycle categories do not automatically use the same test requirements. In the Powered Cycle category, the Diamond test includes angle grinder attacks; the Gold test in this category does not.
For a meaningful comparison, you should consider three pieces of information together: the full model name, the test category, and the level achieved. An abbreviated note such as "Diamond certified" leaves part of this information open.
What does resistance to angle grinders mean?
Angle grinder resistance means that the construction and materials are intended to make cutting through difficult. This does not create a guarantee that a lock will withstand every attack for any length of time. Even a tested model may perform differently under other conditions than in the test procedure.
Specific time indicators are only meaningful within the respective test setup. Tools, cutting discs, mounting, and method influence the result. Therefore, no reliable time span can be derived from a single test during which you can leave your e-bike unattended without concern.
The overall security is also crucial for your decision. A sturdy lock on an easily removable object does not solve the problem. Check the bike rack as critically as the lock: is it firmly anchored, undamaged, and shaped so that the locked bike cannot be lifted over it?
The practical order is: choose a suitable parking location, check a load-bearing attachment point, use a suitable lock, and connect the frame correctly. Only this combination utilizes the lock's properties in everyday life.
How to lock your e-bike correctly
Connecting the frame and a fixed object
Simply locking the bike only blocks the wheel. Connecting it also joins it to its surroundings and makes carrying it away more difficult. Proceed systematically:
- Check the attachment point: Choose a firmly anchored bike rack or a comparably load-bearing, permitted locking option.
- Include the frame: Guide the main lock through a suitable area of the frame and around the fixed object.
- Keep components clear: Avoid pressure on brake lines, gear cables, and sensitive surfaces.
- Check the locking: Verify that the lock is actually closed by pulling on it briefly.
- Check accessories: Additionally secure easily removable parts or take them with you.
Locking only the front wheel is problematic: if it is removed, the remaining part of the bike can be stolen.
Considering wheels, battery, and removable parts
If the opening is sufficient, you can lock the frame and one wheel together. For other components, a suitable additional security measure may be appropriate. When it comes to bike accessories for anti-theft, you should always pay attention to compatibility with existing axles and mounts.
A battery lock does not replace a bike lock. For longer parking times, take a removable battery designed for this purpose with you, and follow the manufacturer's instructions. Removable displays, bags, and lights should also not be left unnecessarily on an unattended bike.
An alarm can attract attention, and a tracking system can provide location information after a theft. Both complement mechanical security; they do not reliably prevent the bike from being carried away.
Train stations and bike rooms: keep the parking location in mind
Train stations, bus stops, and communal storage rooms are also relevant locations for theft in Austria. Therefore, do not automatically treat a locked bike room as a sufficiently protected parking space. If possible, additionally lock the bike to a fixed object.
For regular commuting, it is worth checking available bike boxes or controlled parking facilities. Also pay attention to the terms of use and your own security there.
Keep your proof of purchase, frame number, and current photos separate from the bike. These documents make description and identification easier if it is stolen despite being secured.
What should you check for e-bike insurance in Austria?
Whether and under what conditions bike theft is insured depends on your policy and the associated terms. A high-quality lock or a foreign test mark does not automatically mean that all requirements of an Austrian insurance contract are met.
Before choosing a lock, clarify the following points in particular:
- Lock requirements: Are specific types, test marks, or expressly approved models required?
- Locking up: Must the e-bike be connected to a fixed object?
- Parking location: What rules apply outdoors, in communal bike rooms, and in your own basement compartment?
- Parking time: Are there restrictions for nighttime or longer periods left unattended?
- Part theft: Are the battery, display, and other components covered even if the bike itself remains?
- Proof: What evidence is required for the bike and lock, and what is needed after a claim?
Distinguish between burglary from a locked room and the theft of a bike parked outdoors. Do not assume that both situations are covered equally by the same contract.
Have unclear lock requirements confirmed in writing before purchasing, and specify the exact model name. Keep this information together with the invoice and insurance documents. This allows you to specifically adapt your security to the actual contractual conditions.
