Buyers Guide

Welcome to the buyer’s guide, a section where we cover some of the questions you might have after scanning our list above. Most of you that have come to this article are more than likely those who have either just purchased a new bike or have had one stolen in the past and are looking for a lock that is as secure as possible. No matter your reason, we hope that you find/have found what you’re looking for and decide on the right bike lock that works for you!


How we made our list?

This project was incredibly fun for us — despite the simplicity of the products discussed. Bike locks are an essential part of owning a bike for many reasons, we shouldn’t have to explain why that is. We have had our bikes stolen in the past — at first we were frustrated, angry even, but then we realized that we mostly had ourselves to blame given the quality of our lock; a lock that wasn’t as sturdy as we initially expected.

It’s very easy for someone to rush into purchasing the wrong sort of product without thinking it through. The lock we had originally was made from cheap plastic and could have been broken using your hands. We would often joke and state that losing our bike was the best thing that ever happened to us as it forced us out of our comfort zone and into the idea of the article you’re reading right now!

We worked alongside a few of our closest friends on this article — all of whom own bikes of their own and have actually had bikes stolen in the past also. Having multiple eyes on this article at any given time definitely helped us rid any bias that could have taken over this article. Not only that, but having multiple people in the room at any given time allowed us to confirm our thoughts or bounce ideas off of one another to make sure our minds were in the right place!

The goal here was to find some of the best bike locks around right now, something we believe we more than achieved given the diverse list of bike locks you see listed above. Our first step was to source some of the best bike locks around right now. We scoured the internet as well as catalogs to find some of the best bike locks around! This gave us a list of about 35 different bike locks.

A lot of our selections were quite similar to one another in not only the manufacturer but the look/features of them also. The second stage of this process was to eliminate these duplicate locks and find those that were far more consistent/reliable. User reviews on Amazon were incredibly helpful in understanding what other customers had to say once they actually had these products within their possession.

At this point, we had around 13 bike locks left to discuss. What happened next involved purchasing each bike lock and testing it out first hand to see how well it handled being used to chain an actual bike. Each lock worked just a little differently, some more surprising than others in terms of how durable it was.

Each lock was chained to a bike and then marked on a grade out of ten. Not only that, but we tried to break the locks using a variety of different tools to see how each lock handled being tampered with. Bolt cutters, saws, and regular blunt instruments were used to try and wear down each bike lock.

All locks were able to survive our tampering although some did end up scratching and sporting other noticeable damage. This was somewhat of a red flag for us, as over time scratches can dig deep and cause your bike lock to snap. Thanks to this process we were able to finalize our list! We tried to avoid changing our list as much as possible to keep the integrity of the list solid; something we believe we more than achieved!


Types of bike Locks

If you went through our list before reading this section, then you’ll know that there were various kinds of bike locks included, each as effective as the other in their own way. Riders should always choose a bike lock that fits them and their own personal preferences. Before you even think about purchasing a bike lock of your own, you should first outline your reasons for wanting to buy a bike lock.


Cable Locks

Cable locks are the sort of locks you should buy if you like wrapping your bike up securely. Cables tend to be a lot more flexible and lightweight compared to that of D locks and U locks. Most cables tend to come with combinations — although in some cases you’ll find some come with a key lock. In our experience, cable locks appear to be a lot easier to attach and detach with no waste in motion.

The number of dials on your combination might differ depending on the bike lock cable you own. We tend to go for locks with a five digit combination for added security and peace of mind. In terms of security, cables tend to be rather difficult to cut through or pull loose due to the mechanisms found within the lock and the coating found over the top of the cable.


D lock/U Locks

Something a little sturdier that is next to impossible to break through. D locks, and U locks tend to be far more study than cable locks although they are a tad bulkier/heavier in comparison. If you find that remembering a code is somewhat difficult, then owning a D lock/U lock is a lot easier to manage due to the keys you use to lock/unlock these bike locks outright! These locks require a couple more seconds to lock, but it’s definitely worth it if you are slightly worried about your bike being tampered with.


Chain Locks

Chain locks are a lot heavier in comparison to the other two types of locks that we’ve just mentioned. Chain locks offer the maximum amount of security possible out of any bike lock, the only downside comes in having to carry it around with you. Chain locks are next to impossible to snap/bend/break, which definitely provides peace of mind to anyone looking to keep their bike secure!
