What makes the best D lock for an electric bike

Best D Lock for Electric Bike

High-security level

Security is the thing we expect the most from a bike lock. A D-lock is more secure than any other type of bike lock. If you have an electric bike to lock, D lock is the best for you. But, how can you determine if a D-lock is secure enough for your bike or not? Here comes the security rating.

There are 2 major types of security rating systems. One is the Sold secure, and another is the ART. You don’t need to understand what they are or what they mean. Only remember Gold Secure (Sold securely) or 3-star (ART rating) is the minimum level of security for an electric bike lock.

Renowned Brand

There are tons of branded and non-branded D locks available in the market. But very few of them are suitable for an electric bike. Most of the locks can’t serve what they offer. That’s why it’s better to get a D-lock from a renowned brand. Thus, you can ensure good quality of the lock, and you don’t need to worry about security.

For example, my favorite bike lock brand is Kryptonite. All D-locks from Kryptonite is either diamond rated or gold rated.

Moreover, all D-locks are certified and anti-theft guaranteed. So, I can always rely on the brand. However, there are few other renowned brands like Onguard and Abus. Always try to get a D-lock from these brands.

Durability

Alongside security, durability is also a must for a D lock. Some D locks provide good security. But it doesn’t sustain long because of the corrosive material in use. That’s why you must check the lock before purchasing.

Ensure the lock is made of rustproof material. Stainless steel is the best for a bike lock. Besides, a protective coating above it offers even better durability.

However, you also need to be careful about the protective layer. Polymer-based paint remains long on the lock. Whereas other aliphatic colors fade away in a few months.

Key or combination

I don’t know why this comparison seems silly to me. Keys are way safer than combinations. That’s a different discussion that keys can be lost.

But at least the keys will remain in your hand. Other hands, a combination lock seems to be an open invitation for an optimist thief. Anyone can try out the combination to match when you are not close to your bike.

Moreover, thieves have technics to crack the code. So, it’s better to get a key lock instead.

However, while getting a bike lock, make sure it comes with 2 or more keys. It’s essential to get back up when one key is lost.

Ease of use

It doesn’t matter how costly a bike lock you use; you must maintain it. Otherwise, it will get rusty and won’t function well. That’s why ease of use is a must for a bike lock.

It’s good if the shackle is removable. Otherwise, it must be free to rotate around. Thus, it will be easy to clean or lubricate.

However, some locks come with complicated designs. Always avoid them. Get something simple that can lock your bike on the rotor disc.

Warranty

As I said before, most bike locks can’t keep the commitment they promise. So, it’s always best to buy locks with warranties. By this, you won’t need to worry about repairing the lock when it breaks.

Most reputed bike lock brands offer a 1-year warranty for their products. It can be either a replacement guarantee or a free repair service. Besides, very few brands offer a money-back guarantee. All looks good to go. So, get which one seems good to you.

Additional services

The above features are enough to make a good D-lock for an electric bike. But, the best can has even more exciting features.

I can’t mention any specific one but can explain with examples. Consider Kryptonite bike locks. All Kryptonite D locks offer the above features.

In addition, it comes with a lock holder. It helps you to carry the lock without damaging the bike frame. Besides, I can mention the Key Safe program. By registering for it, you will get an extra key twice whenever you lose it by registering for it.
