Kryptonite New York 1410 chain
A 100 cm chain at 4.9kg. Diamond on ordinary bikes, Gold on e-bikes.
Diamond (ordinary bikes)
The 4.9kg weight makes this much more suitable for use at home than for a daily commute.

Verdict
This suits home, garden, or café-terrace use when a D-lock will not reach the only solid object. The 4.9kg weight, with no mount, makes it a poor daily commute lock. Sold Secure lists the chain with its New York disc lock as Diamond for ordinary bikes and Gold for e-bikes; looping the chain twice does not change the grade. Leave this where the bike is stored overnight and take a D-lock when you ride away.

Who this suits
- Home, a garden, or a ground anchor
- A post or terrace railing a compact D-lock can’t close around
- A second layer alongside a D-lock you take on the commute
Less suitable if
- You need something you’ll carry five miles to work
- Your e-bike policy names Powered Cycle Diamond, or you want a lock sold as anti-grinder
- You expected a lightweight chain
A D-lock suits a tight stand. A chain suits extra length. 100 cm of 14 mm New York chain will reach a ground anchor, a second bike, or a post a compact D-lock can’t close around. The 4.9kg weight makes it much more suitable to leave at home than to carry in a backpack every day.
Reach versus carry
Sold Secure lists this chain with its New York disc lock as Pedal Cycle Diamond for ordinary bikes and Powered Cycle Gold for e-bikes. Looping the chain twice can take up slack, but it doesn’t change the Sold Secure grade, and it doesn’t turn an unapproved lamp-post into an approved anchor. Match the lock on Sold Secure’s list, and treat a ground anchor as a separate product if the policy names one.
The listed weight is 4.9kg
The disc lock is part of the kit, with three keys and no frame mount. Pair it with a D-lock you actually carry — often the Evolution Mini-7 for Gold, or the Litelok X1 if you need Diamond on the bike. At home, lock through the frame to something fixed, take up slack, leave the chain where the bike lives overnight, and take the D-lock when you leave the house.
What works well
- 100 cm of 14 mm chain — reach a D-lock can’t match
- Sold Secure Diamond for ordinary bikes, and Gold for e-bikes
- New York disc lock on the chain; three keys listed
What to watch for
- 4.9kg — useful where the bike is stored, awkward as a daily carry
- No frame mount listed — as expected for a chain this heavy
- Not sold as angle-grinder resistant
One thing we’d change
Calling it a home chain in the title would set clearer expectations. Too many listings make it look like a commute lock.

D-lock or chain?
A D-lock is better for a tight stand on a commute. A chain is better when you need length. Many riders use both, and only carry the D-lock.
Is 4.9kg right?
That’s the listed weight for this 100 cm New York 1410 kit. If another listing looks far lighter, it’s a different product.
Can I use it on an e-bike?
Yes, as a home or destination lock, if the policy accepts Gold for e-bikes — that’s the Powered Cycle grade Sold Secure lists for this chain. Almost nobody will carry 4.9kg as their only lock. For Diamond on an e-bike you still take to work, look at the X1.
Does looping it twice make it stronger?
It can reduce slack. It doesn’t change the Sold Secure grade, and it doesn’t turn a lamp-post into an approved anchor. Grade the lock, then the object you lock to.
