    • Indestructible … great if that’s what you need
Size: 5FT Color: Orange
Much stronger and heavier than I expected, so don’t lose the keys. I ended up buying a much lighter one besides this for when I would be leaving the bike Somewhere too conspicuous for anybody to work on it with a cable cutter. But this one will definitely keep your stuff where you want it Day or night. ... show more

    • FIROS Bike Chain Lock 5FT Hardened Steel Bike Lock

The lock worked great for what I needed it for. The chain is the right length for locking the back and front tires of my bike.

    • Feels sturdy and may deter basic theft
Size: 5FT Color: Black
I have no less than 3 options to secure my ebikes. Maybe overkill, but if this lock keeps my bikes, my bikes. It's all good. While this lock does not seem up to similar specs as the brand superman is afraid of. I use it in conjunction with that higher priced lock from that company I also own. I wanted this lock because I needed length without the super overpriced price. The only down side is the glaring white logo announcing this is lower priced China lock and chain. Wish these fake brands from China would stop tagging everything so boldly. ... show more

    • Best solution that I have found so far
Size: 5FT Color: Black
When we tour, I like to use one locking device to take care of both bikes. We have tried different solutions, but all had drawbacks. The combination of a U-lock and cable was good theoretically, but it was heavy and awkward in practice. A simple cable lock, if thick enough to deter thieves, is really bulky and hard to carry. For this year's tours, I wanted something that would keep the bikes safe but be easy to work with. This Firos chain lock is the best solution that I have found. Though necessarily heavy, it is extremely supple, so I can wrap the chain around the rack and seat post when moving rather than having to waste precious pannier or trunk bag space. I know that a professional thief could break through it, but the chain is heavy enough to make it a slow and noisy business. I also like the fact that this lock came with three keys, so my touring partner and I can each keep one, and still have one in reserve. Finally, this chain lock is a great value. It cost me half of what I had paid for some of the other locking devices. ... show more

    • Much shorter than advertised
Size: 5FT Color: Black
The quality of the lock itself looks good. That said, I was disappointed that the lock I received only measures 4.5 feet, far shorter than the advertised 5 feet. There is a note saying the chain can be slightly shorter because it is measured by hand, but 6 inches short???

    • Great lock for the price!
Size: 4FT Color: Black
Great lock! For what your paying, it’s a great lock. It’s lightweight, which is not a good thing to be honest.. heavier chain means better protection.I rather it be a little heavier. Especially if your riding an E-bike. You don’t want to go lightweight on a chain lock. That being said, it’s sturdy enough and for the price your paying I can’t complain. There’s good quality here and it’s well made. Comes with 3 keys which is a huge bonus. A+ ... show more
