The ABUS Steel-O-Chain 9809 is a serious chain lock for bikes that need more than a quick café-stop lock. With a 9 mm hardened steel square chain, an ABUS XPlus cylinder and a level 12 security rating, it is a strong choice for commuters, e-bike riders and anyone locking a valuable bike around town.
The main reason to choose a chain lock is flexibility. A D-lock can be very secure, but it can also be awkward when the bike rack is full, the stand is the wrong shape, or you need to lock around a pole or larger piece of street furniture. The 9809 gives you more options for getting the frame secured properly.

Why we like it
The 9809 sits in a useful middle ground. It is much more serious than a cable lock, but still flexible enough for everyday bike parking where the locking points are not always ideal.
The 9 mm square chain gives proper cut resistance, while the XPlus cylinder is made to resist picking and tampering. The textile sleeve helps protect your frame from scratches, and the keyhole cover helps keep dirt and moisture out of the lock mechanism.
Best for
- E-bikes and higher-value commuter bikes
- Daily riders locking up at work, shops, cafés or around town
- Awkward bike racks, poles and street furniture
- Riders who want more locking reach than a D-lock
- Using as a main lock, or as part of a two-lock setup for higher-risk parking
Good to know
Chain locks are strong and versatile, but they are not the neatest lock to carry. If your bike has a basket, pannier, cargo rack or storage bag, that is usually the easiest way to transport it. If you want something that mounts cleanly to the frame, a folding lock may be easier day to day.
For higher-risk parking, especially if the bike is outside for a long time or locked overnight, consider using this with a second lock. A strong-looking setup, good lighting and clear line of sight all help make your bike a less appealing target.
Final word
The ABUS Steel-O-Chain 9809 is a good choice when your bike is valuable enough to need real security, but your parking situation needs more reach than a standard D-lock. It is strong, flexible and well suited to everyday town use, especially for commuters and e-bike riders who want a proper main lock.
