A quick café stop, a few hours at work or an afternoon by the beach can all call for a different approach to securing your eBike.
That's why the best lock for an electric bike isn't necessarily the biggest or heaviest one you can buy. It's one that suits where you park, how long the bike is left and how consistently you're willing to carry and use it.
For most riders, that means starting with a strong primary lock and adding another layer when the bike will be left somewhere longer or more exposed.
Which eBike lock should you choose?
Start with the way you actually use your bike.
Short café or shop stop
A quality D-lock (also called a U-lock) is a practical everyday starting point when you can secure the frame to a solid bike rack or another suitable fixed object.
Longer or more exposed parking
For workplaces, train stations, busy shopping areas or anywhere your bike may be left for several hours, prioritise a higher-security D/U-lock or heavy chain suited to the situation.
A second lock can add another barrier, particularly when securing a wheel as well as the frame.
Portability matters
If you want something compact enough to carry on most rides, a folding lock can offer useful reach without the bulk of a heavy chain.
Security varies significantly between folding-lock models. Check the construction and any independent security rating rather than assuming they all offer the same protection.
Wheels and removable accessories
Cables can be useful as a secondary layer for a wheel, helmet or compatible accessory.
For a valuable eBike, they generally shouldn't be relied on as the only lock.
D-locks and U-locks
D-locks, also commonly called U-locks, are one of the most established choices for bicycle security.
Their rigid shape and strong construction make them a practical primary-lock option for many riders.
Size matters, though. You need enough space to secure the bike frame to a suitable fixed object, but an unnecessarily oversized lock can be awkward to carry and may leave more room inside the lock than you need.
For commuters, café stops and everyday urban riding, a quality D/U-lock is often a sensible place to start.
Chain locks
A heavy chain gives you more flexibility than a rigid D-lock.
That can be useful with unusual bike racks, larger posts or parking spots where you need a little more reach.
The trade-off is weight.
A substantial chain may provide a strong security option, but it's worth being realistic about whether you'll actually carry it on every ride.
For riders who regularly leave their eBike parked for longer periods, the extra weight may be worthwhile.
Folding locks
Folding locks can pack into a compact holder while opening out far enough to secure a bike to many common parking points.
That makes them appealing if portability and tidy storage are high on your list.
But don't choose a folding lock purely because it's compact. Security can vary considerably between models.
Where available, look for an independently tested security rating and check that the rating suits the type of parking you regularly do.
Cable locks
Cable locks are light, flexible and convenient.
That convenience also means they generally make more sense as a secondary security layer than as the main protection for a valuable eBike.
A cable can be useful for securing a front wheel, helmet or suitable accessory while your main lock secures the frame.
Think of it as an extra obstacle rather than the foundation of your security setup.
Look beyond the lock type
Two D-locks can offer very different levels of security. The same goes for chains and folding locks.
Where possible, look for products that have been independently tested by a recognised security-rating organisation.
Sold Secure independently tests and rates security products, including powered-cycle ratings for eBike locks. It is a UK-based rating scheme, not an Australian legal requirement.
An independent rating doesn't make any lock theft-proof, but it gives you a more useful comparison than appearance or marketing language alone.
If your bike is insured, check your own policy before choosing a lock. Some insurers specify particular lock types, ratings or locking requirements.
Lock the frame first
Whatever lock you choose, your first priority is securing the bike's frame to a solid, fixed object.
Avoid relying on a wheel, basket, rack, handlebar or removable accessory as your main locking point.
Where your lock and bike allow it, secure a wheel as well. A secondary cable or second lock can help protect another wheel or removable component.
And don't overlook what you're locking the bike to.
Even a strong lock won't provide the protection you intended if it's attached to a loose fence panel, removable sign or something the bike can simply be lifted over.
Match your security to where you park
A twenty-minute café stop on a busy street is different from leaving your bike at a train station all day.
Think about your highest-risk regular stop, not just your easiest one.
Australian riders commonly leave eBikes around:
- Cafés and shops
- Beaches and foreshore areas
- Workplaces
- Train stations
- Apartment garages
- Shared storage areas
- Home garages
Visible, well-used parking areas with suitable fixed bike infrastructure are generally preferable to isolated corners.
At home or in shared apartment storage, don't assume your bike is secure simply because it's behind a door.
Where practical, use the same frame-to-fixed-object approach you would when parking away from home.
What about the battery and accessories?
If your eBike has a removable battery, display, lights or other valuable detachable accessories, consider whether taking them with you makes sense when the bike will be left unattended for an extended period.
Only remove and store the battery where it's practical and consistent with the manufacturer's guidance.
Remember, removing a battery doesn't replace properly locking the bike itself.
Keep a record of your bike
Good security also means being prepared if your bike does go missing.
Keep:
- Clear photos of the bike
- The frame or serial number
- Proof of purchase
- Identifying details
- Records of major accessories
These details can help when reporting theft, dealing with police or making an insurance claim.

The best lock is the one that matches your routine
There's no single lock that's right for every rider or every parking situation.
For many riders, a quality D/U-lock is a strong everyday starting point.
A heavy chain may make more sense when flexibility and higher-exposure parking are priorities.
A folding lock can suit riders who value portability, provided the model's security level matches the job.
And a cable can add a useful second layer for wheels and accessories.
Start with where you actually park, how long your bike is normally left and what level of security your insurance may require.
Then choose a setup you'll genuinely carry and use every time.
