Description
The Tonyon Heavy Duty Folding Lock is a compact, hardened-steel security lock built to protect your e-bike without the bulk of a traditional chain. It folds down small enough to fit in a saddlebag, backpack, or clip onto the frame using the included mounting bracket, then unfolds to roughly 80cm to reach around poles, racks and fences. A one-key locking design keeps things fast and simple, whether you’re locking up for a quick coffee stop or leaving your bike for the day.

Additional Product Details
Folding locks like this one strike a different balance to a chain or U-lock: the segmented steel links fold flat into a compact bundle for storage, but open out into a rigid loop that’s harder to lever or pry apart than a flexible cable lock. Each joint is protected by an ABS coating, which stops the steel from scratching your bike’s paintwork while you’re wrapping it around the frame or a rack. The included mounting bracket lets you carry the lock clipped to the frame rather than stuffed in a bag, so it’s always within reach when you need to stop and lock up quickly — handy for commuting, running errands, or multiple short stops in a day.
Safety & Usage Notes
No lock can guarantee against theft, so how you use it matters just as much as the lock itself. Always secure the bike’s frame — not just a wheel — to a fixed, immovable object such as a signposted bike rack, solid pole or bollard, rather than a fence or railing that could be lifted over. Where possible, choose a well-lit, visible parking spot over a quiet side street, and avoid leaving your bike locked in the same spot overnight if you can help it. It’s also worth giving the lock a quick check before you rely on it fully — make sure the mechanism engages properly and the mounting bracket is tightened so it doesn’t rattle loose while riding. For extra peace of mind, many Cool Bikes customers pair a physical lock like this with a tracker, so the bike can still be located if the worst happens.
Frequently Asked Questions
How long is the lock when unfolded?
It extends to approximately 80cm, giving you enough reach to loop around most poles, racks and fences.
Does it come with a mounting bracket?
Yes — a bracket is included so you can carry the lock clipped to your bike’s frame instead of in a bag.
How many keys are included?
Two keys come with every lock, so you’ll have a spare from day one.
Is this lock resistant to bolt cutters?
The hardened alloy steel is designed to resist cutting, prying and sawing far better than a cheap cable lock, though as with any lock, determined tools and enough time can defeat most security devices — pairing it with smart parking choices gives you the best protection.
Can I use this on a scooter or motorcycle as well as an e-bike?
Yes — it’s a general-purpose folding lock suited to e-bikes, bikes, e-scooters and similar-sized frames, anywhere you need a fixed point to lock to.
Can I pair this with a tracker for extra security?
Definitely. Our Bluetooth Tracker and GPS Tracker both work well alongside a physical lock like this one, giving you a way to locate your bike if it’s ever moved.
How does this compare to a chain lock?
A folding lock like this is lighter and more compact than a chain, while still offering strong resistance to cutting and prying. If you want maximum size and reach instead, our ETOOK Titan Ultra Chain Lock is a good alternative.
No lock can guarantee against theft. Use this lock as part of a layered approach — secure parking, a visible lock, and where possible a tracker — for the best protection.
