5 Best Lightweight Bike Locks 2018

Bike theft has become a common menace in cities, colleges and parking lots, which has made it hard for bike owners to trust leaving their bike in any of these places. You will leave your bike unattended for 30 minutes only to come back and find out that it is gone. And once it is lifted, chances are that you are never seeing it again. The best way to prevent this is by investing in a good bike lock. If you manage to get your hands on the best lightweight bike locks, you will be sure that your bike is safe since they are unbreakable, secure and easy to use.

Investing in a good bike lock will mainly depend on security, convenience and style. Given the right tools and enough time, even the most secure locks can be broken. Bike locks make more sense for low-medium value bike owners as they are easy to sell off once stolen. However, this doesn’t mean that leaving a $5,000 bike in a public area is safe. It’s like you are saying, “Hey I have an expensive bike would you mind stealing it from me? Thank you.”

Another factor you might want to consider is where and how you lock up your bike. You don’t expect to lock up your bike in a spot that out of view and hope to find it when you return. No! You are simply giving the thief enough time and a quiet place to do his/her thing.

Choosing the best lightweight bike locks

Before you decide on the bike, lock to buy it’s important to understand the different types of bike locks as this will determine the kind of bike lock you get. You will want to know the upsides and downsides of using the different types of locks.

There are four main types of bike locks, which include:

  1. U-locks
  2. Chain locks
  3. Folding locks
  4. Cable locks

U-Locks

U-locks are lighter, a little bit easier to use and cheaper than their chain counterparts. They do all these and still manage to offer the same level of protection. Unlike chain locks, U-locks are rigid which makes it harder to transport them and their size limits the number of places/things you can lock your bike to.

Pros

  • Lighter than chain locks
  • Cheaper than chain locks

Cons

  • They will not fasten around larger objects

Chain locks

Chain locks mainly consist of a long chain that is usually covered by a sleeve in a bid to protect the paintwork. The chain lock will also have a big lock to secure your bike.

Chain locks can be classified into two categories; there are the portable chain locks and there is the stationary chains, which are super heavy.

The portable chain locks are easy to move around as you even wrap them around your seat post and use them when the need arises. The only problem with portable chain locks is that they are most 12 mm thick, which makes them easy to cut through. They might be heavier than U-locks but they are definitely less secure.

However, when it comes to the stationary chain locks, they are arguably the best way to lock a bike since they are heavy, super thick and made from core-hardened steel. Since they are heavy, stationary bike locks are best used when securing your bike for extended periods.

Pros

  • Easy to transport
  • Easy to fasten around objects

Cons

  • Expensive
  • Cumbersome

Folding Locks

Folding locks comprise of metal plates that are linked together by use of rivets. The rivets are designed in such a way that they allows the metal plates to rotate thus allowing you to fold your folding lock into a tight package, which can be folded out when the need arises. Once fastened around your bike they form a stiff shape.

Generally, folding locks are lighter than their U counterparts but offer the same level of security. They are more flexible and longer which gives you much options than your standard U-lock.

Like earlier mentioned, folding locks fold down easily to make a compact package that is portable. While in the compact package, you can put it in a carrying holster that you can screw onto your bottle holder.

Pros

  • Flexible and lengthy
  • Easy to transport

Cons

  • Limited choice

Cable Locks

Generally, cable locks comprise of numerous strands of thin long steel that are braided together and coated using a plastic tube. They are super light, cheap and definitely flexible. However, the flexibility aspect comes at a cost as it means that they can be cut with bolt cutters in seconds.

And since every bike thief equips himself with a pair of bolt or cable cutters, your cable locks are less likely to offer much security. However, not all cable locks are flimsy; you can buy the armoured cable locks, which are better than your typical cable locks but not as secure as a chain lock or the best u-lock.

Pros

  • Cheap
  • Light and long

Cons

  • Do not offer adequate security
