It is long enough to secure your bike to a bike rack. The chain itself is so Rigid and Strong. The built of this bike lock is well thought of. The other selling point for this is, there are 3 keys. It is a plus for me. I also like that the chain is covered with a durable cloth. It prevents scratches on the bike.I owned a 2019 Rad Rover with Accessories. People cant keep their hands to themselves. Every time I parked outside a convenient store or chick fi la, by standers often check it out and maybe trying to figure it out on how to steal it. But when they see that there is a chain lock, they just move on to the next one. I am buying another one to use it with my other bikes. You dont want to lose you hard earned Bike $$$$.This is a great value for your money. I highly recommend this product every bike owners and motorcycle owners. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Peace of mind that your bike is safe, and amazing customer service not seen much anymore. *by S***R on Reviewed in the United States on April 24, 2019* We love this bike lock. Unfortunately, we live in a city where a lot of bikes are stolen. Not with this bad boy, not today. About a half inch of chain--oh yes--now you're talking my language--I don't worry about anything when I am shopping. Have gotten 2 compliments and have only had it a few days. This is my 2nd lock by SIGTUNA, the first being a foldable bike lock. The quality is equally as good as the chain type. Your bike won't get stolen with these locks. SIGTUNA products are amazing. The quality of their locks makes me want to see what else they sell. Juna at SIGTUNA has given me one one one, most excellent customer service. Best customer service I have received in a very long time. Luna really turned things around for me, and I like shopping with companies that hire employees like Luna. I will always give SIGTUNA my business first, because of the way I was treated. Luna, I appreciate you and SIGTUNA. ### ⭐ 1.0 out of 5 stars my bike is stuck inside the lock. *by R***S on Reviewed in the United States on November 9, 2018* After purchasing the same terrible bike lock from Amazon two times, I decided it was time to search for a new one. I was interested in this lock because it seemed heavy duty and affordable.At first, I liked this lock. I thought that it would keep my bike safe, and I prefer a key lock. After the first few uses, the lock began to feel like it was corroding (though I would always close the seal that protects the keyhole), and it started getting harder to open and close it. Then, it began feeling normal again, opening and closing with ease. However, for the past two weeks, my bike has been locked inside the lock. I've tried countless times unlocking it; I have even tried using one of the two spare keys in hopes that the issue was with the key and not the lock. I am beyond frustrated with and disappointed in this product, and quite frankly, with Amazon. I have no idea how I am ever going to use my bicycle again.I guess I learned my lesson: don't buy a cheap lock. You truly do get what you pay for. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/57168153-sigtuna-chain-locks-heavy-duty-8mm-bike-chain-lock-key](https://www.desertcart.vn/products/57168153-sigtuna-chain-locks-heavy-duty-8mm-bike-chain-lock-key) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
