After reviewing the top-rated e-bike locks to help keep your bike secure, we can now move on to our buying guide which will cover the different types of bike locks on the market, what to look for in your bike lock, tips for locking up your e-bike and how to protect your electric bike from theft.
Having a level of protection for your electric bike is more important than ever at the moment, e-bike theft is on the rise, especially after the pandemic, when more people took to getting electric bikes.
On average, around 113,000 bikes have been stolen in the UK over the last year, the actual risk level is much higher for e-bikes, being 3x more likely to be stolen than a standard bike. It's not just the e-bikes themselves which are getting stolen, but also components such as the motor, battery and GPS.
Electric bike thieves can be split into two types, opportunist and professional, the latter typically carry around tools such as cable cutters and hydraulic jacks. Typically, your e-bike will often be targeted if it has a cheap bike lock, like a combination lock since they are easier to get into.
This is why choosing the best lock is important.
So as you can know what you need to be protecting your e-bike against, we've listed the main ways and tools that thieves commonly use to steal e-bikes below.
Hydraulic jacks are powerful enough to lift a car off the ground, which also means they are powerful enough to snap a bike lock, they are used less commonly however since they are bulky to carry around, these would mostly be used by professional thieves.
The best way to avoid this theft is by using a smaller shackle so that the jack cannot fit through the space.
Cable cutters are a very common form of bike theft tool due to their miniature size which can fit easily into your pocket, this allows thieves to get through cable locks with ease. To avoid this type of theft happening to you, use a metal lock which a cable lock will prove useless against.
Freezing bike locks is very uncommon, but it is a way to shatter locks and steel electric bikes, freezing locks to cold enough temperatures. Most of the top types of locks will be resistant to extreme temperatures, so freezing them will not work. Also, keep the lock further from the ground so striking it will be harder.
Portable grinders are a tool which can get through nearly any kind of bike lock, they are not used often however since they can make a lot of noise during the grinding process.
There is no lock on the market which can prevent being opened by an angle grinder, the best you can do to prevent your bike from these tools is by using a very thick lock so that it can take longer to grind through, securing the bike with two not just one lock will always deter thieves too since it's more time-consuming.
Hacksaws are cheap and easy to use, whether they are kept in your pocket or a backpack, they are a common tool for bike thieves. A hacksaw with multiple teeth could get through a bike lock cable with ease, hardened steel locks will make this harder.
Bolt cutters can be miniature, with some being just 6-inches in size, making them a popular tool for bike thieves. They can get through cable locks and D-locks with ease. For cable locks, try to get one with a thickness over 16mm as this will make it more resistant, hardened steel locks are also a better choice.
Avoid unbranded cheap locks, believe it or not, these can be pulled apart with your hands if there is enough tension. Ensure you are choosing a sold secure type of lock with a gold rating or silver rating to avoid this possibility.
Hammers can be used to break open cheap bike locks with enough blows, keeping your lock far from the ground can help with this. Crowbars can also be used for twisting locks, making sure the shackle is full on your lock will help to prevent this.
Now we know the types of thieves and what they will be using to try and open your electric bike locks, we dive into looking at the different types of e-bike locks and their pros and cons.
D-locks are also known as U-locks, they are one of the most common kinds of bike locks on the market and work by having a u-shaped bar connected to a locking mechanism.
These kinds of locks can be large enough to loop through to a bike rack or inserted through the bike's tire or rear wheel and frame to stop it from rolling.
The pros of D-locks and U-locks are that they are very tough, and they also do not tend to weigh much which makes them portable. These top-rated locks can be difficult to loop through bike frames however and some can be very heavy, making them harder to carry.
Cable locks typically come in both combination and key varieties, they are designed with a locking mechanism in between two cable ends. You can typically find cable locks designed with either steel cable twisted together or armoured shells over wires.
These types of basic bike locks are very lightweight and easy to carry but offer the least security since they are easy to cut through with cable cutters. We would suggest using this basic lock as more of a secondary lock.
Chain locks are made with metal links and a lock, they do provide decent security as budget locks but this does depend on the size of the chain links, with a bulky chain lock weighing a lot.
Another benefit of chain locks is that they can be looped around nearly any kind of electric bike, you just need to consider how you will carry the lock.
Folding locks are newer designs of lock and are made from unfolding metal bars, decent quality folding locks are as secure as D locks and have a lightweight, you can also secure them to multiple points on your electric bike.
After learning about all the different types of electric bikes, we can move on to looking at the key features your best electric bike lock should have.

Even if you buy the best top-end model lock, you still need to know the best way to lock up your bike to protect it from a potential thief.
