  • High quality, for peace of mind
Color: Black 4MM
High quality! Strong! I am using this to tie down and securely lock my mobility scooter to my ramp on my vehicle. I am very happy with it. Now I feel extremely safe to be able to leave it on my vehicle, knowing it will be too hard to steal.

  • Good budget chain lock, solid for everyday use
Color: Black 6MM
This Weogine bike chain lock is a good option if you need something simple and affordable for basic security. The chain feels sturdy and has a decent weight to it, which gives some confidence when locking up your bike. It’s made from alloy steel with a protective cover, so it holds up well against weather and doesn’t scratch your bike frame easily.  The length is also practical, making it easy to lock your bike to racks, poles, or fences. It comes with multiple keys, which is helpful in case you lose one, and the locking mechanism works smoothly without sticking. This isn’t a super high-end lock, so I wouldn’t rely on it in high-theft areas, but for school, quick stops, or lower-risk areas, it does the job well. ... show more

  • Better than a cable lock
Color: Black 4MM
This is a nice bike chain for the money. It's definitely better than a cable lock to keep your bike safe. The chain itself isn't very thick but the cover hides the fact from would be bike bandits making it a great deturent. It's good for the money you pay!
