Best Lightweight Bike Lock

A lightweight bike lock. That’s what we all want isn’t it? And the best lightweight lock will be easy to carry around and will also keep our bike safe. It’s not too much to ask, is it?

Well, there are loads of lightweight bike locks. The shops are full of brightly coloured cable locks and spindly armed u-locks. And they’re usually really cheap too. But the problem is: none of them will protect your bike!

Why? Well, unfortunately there’s a direct link between weight and security. And generally, the lighter a bike lock, the less secure it is.

But hold on, hold on! Before you run off, there are lightweight bike locks that will protect your bike. They’re just not the feather-light tat you’ll find in the shops.

So keep reading and I’ll introduce you to seven bike locks that don’t weigh a ton and will actually keep your bike safe.

But before we start, a quick clarification. All the lightweight bike locks here offer at least Sold Secure Silver levels of protection. I don’t recommend locks that are less secure than this, as they won't stop your bike from being stolen!

If you’re not sure who Sold Secure are, or how to decide what level of protection you need, check out my complete guide to choosing the best bike lock.

In the meantime, here are 7 of the best lightweight bike locks currently available:

1. TiGr Mini: Lightest Lightweight Bicycle Lock!

If (low) weight and (easy) portability are your priorities, and your circumstances are low risk, then there's no better bike lock than the TiGr Mini.

While most bike locks are made from steel, the TiGr mini is mostly titanium. And since titanium has unparalleled strength to weight ratios, this is the lightest, mid security lock available today (by some distance).

TiGr mini: Lightest mid-security bike lock

Shackle thickness:

1.25" / 32 mm

Weight:

0.9 lb (0.4 kg)

Size

4 x 7" (10 x 18 cm)

Other Security Ratings:

ART 2 Stars

Weighing just 0.9 lb (0.4 kg), the TiGr mini isn’t much heaver than 1 can of Coke! And it’s 50% lighter than the Kryptonite Evolution LITE Mini-6 which is the lightest u-lock offering the same level of protection.

But how secure is it? It hasn't been tested by Sold Secure. However, ART the Dutch security organisation have, and they awarded it 2/5 stars. This is roughly equivalent to a Silver rating from Sold Secure, and makes the TiGr a mid-security bike lock.

So it’s not a lock for valuable bikes in high risk areas. And it’s not a lock to protect your bike for long periods. But it’s fine for quick stops in lower risk areas and it would make a great secondary bike lock in more risky circumstances.

And it’s not just light. A great frame mount makes it really easy to carry around. It looks great. And you’ll get fantastic after sales support from a US company that really cares about it’s product and it’s customers.

The TiGr Mini is very small: so locking options are limited

It’s a very small lock, so you’ll need to make sure it’s suitable for your bike and the places you want to secure it. And it’s also pretty expensive [Amazon].

But if you’re looking for the lightest bike lock currently available that offers a decent level of protection, you should definitely check it out. Read my in-depth review of the TiGr mini here.

2. Abus Granit X-Plus 54 Mini: Strongest Lightweight Bike Lock

The Abus Granit X-plus 54 Mini has more independently awarded, high security ratings than any other lightweight bike lock.

Shackle width:

Weight:

2.56 lb (1.16 kg)

Size (internal):

4.23 x 5.51"

(10.8 x 14 cm)

Other Security Ratings:

It’s a very special lock. Pretty light and incredibly secure, I can’t understand why it’s so often overlooked.

Not only is the 54 Mini rated Sold Secure Gold. It’s also Sold Secure Motorcycle Gold. And it has 3/4 stars from ART. All this means that it’s a very, very secure lock.

And because of it’s special parabolic 13 mm shackle, it still only weighs 2.56 lb (1.16 kg). Which is incredibly light for lock as secure as this.

Obviously it’s a mini u-lock, so again, it’s very small. But measuring 4.23 x 5.51″ (10.8 x 14 cm), it’s actually pretty wide for a smaller u-lock, so your locking options won’t be quite as limited as other minis.

The Abus Granit X-Plus 54 Mini is wider than other mini u-locks

Again, it’s not cheap [Amazon] by any means. But a relatively light, high security lock never will be.

So if you’re looking for a more traditional lock with an incredible security to weight ratio, the Abus Granit X-Plus 54 Mini could well be one of the best lightweight bike locks for you.

3. Litelok Silver: Lightest Sold Secure Silver Bike Lock

Litelok now have a Sold Secure Silver rated lock to go with their Gold bike lock. It’s made from the same “Boaflexicore” material but there’s less of it, so it’s obviously lighter (but less secure) than the Gold version.

Other Security Ratings:

And they’ve made some improvements in the usability too. A vertical locking motion makes it easier to close, and a naturally circular shape makes it easier to get around whatever you’re locking your bike to.

And it’s also designed to be worn around your waist like a belt. So it's really easy to carry around when your riding.

Plenty of locking options with the generously sized Litelok Silver 70

It’s not quite as light as the TiGr Mini, but it has much bigger internal dimensions, giving you far more locking options.

I tested the 70 cm version. But it's available in 2 other sizes. Plus there's 2 "U" shaped versions which are smaller (so can't be worn like a belt).

So if you don’t need a super secure bike lock, and you’d like easy portability and lots of locking options, this is one of the best lightweight bike locks around. Read my full review or the Litelok Silver.

4. Kryptonite Evolution Mini-6: Best Lightweight Mid-Security U-lock

The Kryptonite Evolution LITE Mini-6 [Amazon] is the lightest Sold Secure Silver u-lock currently available. And apart from the TiGr Mini and Litelok Silver, this makes it the lightest, mid-security bike lock, full stop.

(7 x 15.3 cm)

Other Security Ratings:

Sold Secure Silver

It’s clearly a mini u-lock, measuring just 2.75" x 6″ (7 x 15.3 cm). And while that doesn’t make it particularly short for a mini U-lock, it does make it very narrow. In fact it’s one of the narrowest u-locks on the market.

So make sure it’s suitable for your bike and the places you’ll be locking your bike before you buy it. Because you’re pretty much limited to bike stands with this one.

Kryptonite Evolution LITE Mini-6: too narrow to get around seat post and wheel

The shackle is only 11 mm thick, but it’s made from a “MAX-Performance” steel that’s as strong as some of Kryptonite’s other 13 mm shackles.

And this is reflected in the security ratings, with Sold Secure giving it a Silver award. In fact, it’s the only 11 mm U-lock with a Sold Secure Silver award.

But it’s not double-bolted (it features Kryptonite's famous "bent foot" shackle). And this is not a primary lock for high risk areas.

But just like the TiGr, it’s a great lightweight lock for less valuable bikes, less dangerous areas and shorter stops. And like the titanium lock, it would also work well as a secondary lock.

So if you’re looking for a super light bike lock at a very reasonable price [Amazon], this is one of the best lightweight bike locks currently available.

5. Foldylock Compact: Best Lightweight Folding Bike Lock

Folding bike locks are not generally light. They're not as heavy as chains. But they're heavier than similarly sized u-locks. And while the Foldylock is no exception to this rule, it's the lightest folding lock currently available.

Foldylock Compact

My score:

Check price:

Bar thickness:

5 mm

Weight:

2.2 lb (1 kg)

Length:

33" (85 cm)

Other Security Ratings:

Sold Secure Silver

The Foldylock weighs 2.2 lb (1 kg), making it one of the heaviest locks on this list. But the best thing about folding locks is the way they collapse down into a really small package that makes them the easiest bike locks to carry.

If you use the frame mount (which you can either screw into the holes meant for your water bottle, or fasten round your frame with Velcro), the lock lies very close to the frame, which means there's no movement or rattling while your riding.

And again, because it's so small when folded down, if you throw it in a bag you'll barely notice it's there!

Foldylock Compact: probably the most practical lightweight lock

The Foldylock is also incredibly easy to use. When extended, it gives you the same locking area as a standard size u-lock. But because it's flexible, it gives you loads more locking options than any u-lock.

It's rated Sold Secure Silver, so it's a great lock for lower risk circumstances. And it's probably the most practical, easy to use option on the best lightweight bike locks list!

So if you're looking for a lightweight mid-security lock, that's easy to carry and gives you loads of locking options, check out my full, hands on review of the Foldylock Compact.

6. Litelok Gold: Lightweight and Flexible

The bigger, tougher brother of the Litelok Silver, this is Litelok's original bike lock. And it's made using the same “Boaflexicore” technology.

Litelok: lightest high-security lock

Litelok Original

My score:

Width:

2.5" (6.5 cm)

Other Security Ratings:

Sold Secure Gold

The innovative construction enables the Litelok to be the same length as a cable or chain lock, but weigh less than many high security mini u-locks, and still provide Sold Secure Gold levels of protection!

The Litelok is 29″ (74 cm) long, making it the same length as a chain like the Hiplok. And that’s not super long. But it’s long enough to give you loads more locking options that you get with a u-lock.

Litelok Gold: lightweight and flexible

So what’s the drawback? Well, it’s quite expensive. It’s quite bulky. And it’s not as flexible as a cable or chain. This means getting it around your bike can be frustrating and carrying it about is more challenging that you’d imagine.

However, Litelok have recognised that portability isn't just about weight, (it's also about bulk and the way you carry a lock on your bike). And they've introduced a wearable version of the Litelok Gold that allows you to strap it around your waist like a belt.

This wearable Litelok Gold is a marked improvement on the original Litelok that I tested, and is definitely the best lightweight bike lock they make. It's available in three sizes...

Litelok Gold Small
1.31 kg
92.5 cm

Litelok Gold Medium
1.40 kg
100 cm

https://geni.us/hB6sM

Litelok Gold Large
1.46 kg
107.5 cm

There has plenty of discussion about how secure the Litelok really is. But it has been rated Sold Secure Gold. And they're so confident about how well it will protect your bike, that they offer their own "theft protection" scheme.

So if you're looking for a Gold rated lock that will offer you loads of locking opportunities but that doesn't weigh a ton, it might just be the best lightweight bike lock for you. Read my full, hands-on review of the Litelok.

7. Tex-lock X-lock: Lightest Sold Secure Gold Bike Lock

A bit of a strange one to end on! The Tex-lock is an innovative German bike lock that combines a textile sheathed 6 mm chain with a mini u-lock that they call the "X-lock". It's worth reading my full review to get your head around how this works!

Tex-lock X-lock

My score:

Check price:

Shackle width:

12 mm

Weight:

0.99 lb (0.45 kg)

Size (internal):

Other Security Ratings:

Sold Secure Gold

But the most important thing here, is that the X-lock is currently the lightest Sold Secure Gold rated bike lock. And that's because it's tiny! 

Measuring just 5" x 1.93" (12.7 x 4.9 cm) it really is small. It only just goes around a Sheffield bike stand. And even then, the rubber sheath catches and you have to force it over slightly.

Lightweight Tex-lock X-lock in use on bike

The Tex-lock X-lock only just fits around a Sheffield bike stand

I'd imagine that the people at Tex-lock didn't design it to go over a Sheffield bike stand. But it's a shame they didn't make the lock just a couple of millimetres wider as then it would be a perfect fit.

I'll probably remove the rubber sheath that covers the shackle on mine. This should get rid of the stickiness, but obviously a naked metal shackle is much more likely to scratch your paint work!

As it is, it just about fits. And that means that for those of us in cities and towns that almost exclusively use these stands, the X-lock is a great option. It's so small it can genuinely slip into your pocket.

You won't be able to secure either of your wheels (you could use the textile/chain lock for that, or look at other options). And you've got to apply a bit of pressure to get it around the stand. 

X-lock with chain

You can use it with a textile sheathed chain too

But if you're looking for the smallest, lightest, Gold rated lock that's usable on it's own, then the X-lock could be the best lightweight bike lock for you!.

If it sounds a bit too restrictive, then the Abus Ultimate 420 140 [Amazon] and the Seatylock Mason 85 140 [Amazon] are the next lightest Gold rated bike locks and more "sensibly sized".

These are definitely two of the best lightweight bike locks that are both high security and practical to use (as long as you're prepared to modify your locking technique).

Abus Ultimate 420 140

Just be careful that you choose the Gold version if you go for the Abus Ultimate though as it used to be rated Sold Secure Silver and there could still be a few of the older models hanging around!

Best Lightweight Bike Lock Summary

So those are the 7 best lightweight bike locks available today. Locks that will actually protect your bike!

When you’re choosing your lock, think carefully. All bike locks offer a balance of three qualities:

  1. price
  2. practicality
  3. security.

You need to find a balance where your lock is affordable and easy to use and (most importantly), secure enough to prevent your bike from being stolen.

If you want a particularly lightweight bike lock then you’ll need to make sacrifices elsewhere. Maybe it will be smaller. Maybe it will be more difficult to use. Maybe it will be more expensive.

Maybe it will be slightly less secure. Just remember that security is the most important job of any lock!

Make sure you’re aware of the security level you need for your circumstances and choose from the best lightweight bike locks that meet that security level.

Never buy a cable lock. And never go less than Sold Secure Silver!
