6 Things to Know Before Buying Folding Locks
Not satisfied with cable-style locks that don’t offer enough protection and u-locks that are simply too heavy or bulky to tote around.
Wish there was a middle ground? Folding bike locks offer the best of both worlds.
Their metal plates make them a very secure way of protecting your bike while their foldability makes them perfect for toting on your bike frame.
That said, not all folding locks are created equal. How much security do you need? What will fit on your bike? How much do you need to pay to get the security you want? We’ll answer those questions and more while also providing you with a list of our favorite foldable locks.
1. Size and Length
The size and length of a folding lock are important for two reasons.
These factors determine how much you can wrap the lock around when unfolded as well as how easy it is to store when it is folded up.
You want a lock that will extend long enough to wrap around your bike and whatever it is you’re securing it to.
2. Ease of Carrying
The ability to easily and compactly store your bike lock is the advantage of a folding lock vs. other types of locks.
All folding locks include brackets that allow you to mount them to your bike for easy transport. You’ll want to make sure the mounting brackets are compatible with your bike’s frame.
3. Locking Mechanism
Unlike some other lock types, with foldable locks, you have the option of choosing between a combination system and keys.
Combination systems allow you to set a number combination, while key system locks come with a key and several spares.
Both have their pros and cons.
Consider which locking mechanism works best for you when deciding on a foldable lock.
4. External Coating
Due to the nature of a folding lock, it will frequently come into contact with your bike’s frame.
With that in mind, you’ll want a lock that isn’t going to scratch up your finish or dig into its carbon frame.
A foldable bike lock made out of steel isn’t going to be a particularly light addition to your bike.
That said, you want to find a lock that is going to add a manageable amount of weight.
Bigger may mean more secure, but it also means heavier.
Locks like Inbike’s folding lock may be lighter, but don’t offer a high level of security. Consider this when determining how big a lock you need to adequately protect your bike.
6. Security Rating
It’s become commonplace among bike lock makers to provide a security rating for each lock that they manufacture.
While these security ratings are helpful, it’s also important to understand that each manufacturer comes up with its own rating system and rates its own locks.
For example, Abus rates its locks from 1 to 15. On the other hand, Foldylocks has a security scale between 1 and 18 with 18 being the most secure lock they offer while Kryptonite rates its locks on a scale of 1 to 10.
Because lock manufacturers come up with their own set or criteria, it’s impossible to make an apples to apples comparison across brands.
