This lock is awesome,you may want to change the lock itself. The lock seems a little flimsy but definitely does the job. The chain itself makes this worth the money

So far it's been a good chain and lock. I think just the sight of it deters would be theives. It's very durable, and good length that I can lock up to almost any bike rack or post. Really heavy but good secuity.

Big ole deterrent, match it up with another lock and make thieving difficult and time consuming.

But lock is a little understated and small so it is awkward to use to get both chain ends on and lock.

It's thick and sturdy. Feels very secure. Heavy, but not too heavy to carry in your backpack if you have a healthy back. I wish it was longer as it's hard to wrap it around the bike and a thick object like a tree as well. Nearly impossible. Have to chain it to something much thinner like a pole

I have my e bike to lock it and it’s very length, lock works very well.

This system coupled with a movement alarm is a perfect security mechanism

The chains seems okay but you can get a better one for a fraction of the price at a hardware store and the lock is much smaller then it looks in pictures doesn’t feel sturdy I wouldn’t trust it on a bicycle let alone a motorcycle I initiated the return 4/4 not estimated refund is 5/7 I’ve a month to get my 55$ back
