The bicycle chain lock is wrapped by a high quality polypropylene fabric, which is scratch-proof and wear-resistant, anti-hot and anti-icing hands; it protects the chain and prevents it scratching your bicycle frame, long lifespan.
Very simple and quick to use. You just choose your own combination and it works perfectly. Don't have to worry about scratching.Having both keys AND a numerical combo feature is so so handy.Very easy to use, very strong, I feel it’s very rugged which nice.Have two ways to open this lock. Forget the code, you have the keys or vice versa. The lock is easy to open either way. It is very flexible and lightweight, but strong enough to stop a quick nab of your bike.
The chain lock long enough to lock 2-3 bikes together, or lock your bike to a tree, gate, fence, railing, thick pole and others. The lock can also be used for motorcycles, scooters, skateboards, grills, ladders, doors, lawnmowers and many others. NDakter provides a one-year warranty, we'll either replace it at no cost or issue you a full refund. NOTE: The male end of the chain is 1.25" diameter, you'd better confirm the gap of spokes/hole to wrap through before your purchase. Otherwise, you can only lock your scooter by winding instead of the gaps in the wheels.

This is a nice but sturdy security chain lock for your bicycle. Comes with a combination lock which is easy to set. The dials are of a decent size, even fir my large fingers. Also comes with a key in case you have forgotten your set combination code, which allows you to open the lock and allows you to reset a new code.Ideal for children or if you have to secure your bicycle for a short period of time. If you have to leave your bicycle for a long period of time at a public parking place, I would recommend a lock of higher security quality.

The NDakter bike chain lock is an excellent choice for securing my bike. The 4-digit combination is easy to set up, and having the key option adds an extra layer of convenience. The chain itself feels heavy-duty and durable, giving me confidence that my bike is well-protected. It’s the perfect length for securing to bike racks or posts, and the protective cover on the chain prevents scratches on the bike frame. Overall, it’s a great, secure lock that’s easy to use and offers peace of mind. Highly recommended for anyone needing a solid bike lock!
