Most electric bicycle owners start their security research by comparing locks. Which steel is hardest. Which rating is highest. Which shackle is thickest.
That comparison makes sense on the surface, but it skips over something important. Thieves do not evaluate locks. They evaluate situations. Specifically, they look at how long the job will take, how much noise it will create, and whether anyone will notice.
Those three factors decide which bicycle gets targeted and which one gets left alone. Understanding what a thief actually checks before acting is more useful than understanding which lock scored highest on a rating chart.
It also helps to understand why electric bicycles get targeted more than standard ones. An electric bicycle contains a battery, a motor, a display and a frame. Each of those components sells individually, and none of them carry traceable serial numbers. That makes electric bicycles significantly more valuable to resell in parts, which is why they are selected more often at public racks.
How many locks are on it
The first thing a thief evaluates is how many locks are securing the bicycle. This check happens from a distance, often from across the street.
One lock means one point to get through. Two locks means two separate points to get through, which doubles the effort and the time required.
This is not about whether one lock is strong enough. It is about how many obstacles are visible before he even approaches. A bicycle with two locks on it reads as a harder job immediately, and in most cases that is enough to redirect attention to an easier target nearby.

How long will it take
Time is the most important factor in every theft. The longer a thief has to stand in one place working on a lock, the higher the chance that someone walks by, asks a question, or calls the police.
A single lock, regardless of its quality, creates a single task with a defined time window. A second lock creates a second task on top of the first.
Published security guidance from the US Department of Justice recommends using two locks of different types for maximum protection, specifically because different locks require different tools and techniques, which compounds the time required.
One strong lock can still be defeated in a short window. Two locks turn a short window into a long one, and most thieves are not willing to stay that long.

Will it make noise
No lock produces sound. That is not a criticism of any lock, it is simply a limitation of what locks do. They resist physical force. They do not alert anyone.
This matters because silence is a requirement for theft, not a preference. If the job is quiet, nobody nearby has a reason to look over.
A motion alarm changes that completely. The moment the bicycle is touched or moved, the alarm activates and produces a loud, sustained sound.
Research from the University of North Carolina at Charlotte found that roughly 60 percent of convicted burglars said the presence of an alarm would cause them to choose a different target entirely. The study also found that the proximity of other people was one of the top factors offenders considered. An alarm forces both of those conditions at once: it creates noise and it draws the attention of everyone nearby.

Is anyone watching
A thief needs to look unremarkable for the entire duration of the job. Someone crouching beside a bicycle for 20 to 30 seconds can easily pass as the owner adjusting something. Nobody intervenes because nobody has a reason to suspect anything.
That changes the moment an alarm goes off. The person crouching beside the bicycle is now the centre of attention on the entire street.
Anonymity, the ability to blend in and go unnoticed, disappears instantly. This is the factor that most security setups fail to address. Locks handle time. Nothing in a standard lock setup handles visibility. The alarm is the only component that forces a thief into public attention while he is still at the bicycle.

Is there a complete setup or just a single lock
Most people who understand the value of a second lock and an alarm still end up with an incomplete setup. They buy one lock first and plan to add the rest later. The second lock gets delayed. The alarm never gets ordered.
Each individual purchase feels optional on its own, so the full setup rarely comes together.
A security kit solves this by making the complete setup a single purchase. The Klyra Bicycle Security Kit includes two folding locks and a motion alarm, designed to be carried together using included frame mounts.
It also includes a theft replacement guarantee, meaning if your bicycle is stolen while properly secured with the kit, you receive a replacement or a full refund. The kit exists because the individual components only work as a system. Two locks without the alarm leave noise unaddressed. An alarm without two locks leaves time unaddressed. The full kit covers all three factors in one order.

The Klyra Bicycle Security Kit
Two folding locks and a motion alarm, designed to be carried and used together rather than assembled over months.
- 2 folding locks, so the count reads as two jobs rather than one
- 1 motion alarm, the only component that addresses noise
- Mounts included, so both locks travel on the frame
- Theft replacement guarantee

The two paths from here
Electric bicycle theft is not a strength problem. It is a deterrence problem. A thief evaluates how many locks are present, how long the job will take, whether it will be quiet, and whether anyone will notice.
A single lock, no matter how well built, only addresses the first of those factors. Two locks and a motion alarm address all of them.
Where to buy
The Klyra Bicycle Security Kit is only available through the official Klyra website. Folding locks and alarms that look similar do appear on third party marketplaces and in retail stores, but they often ship without the matching mounts, without the second lock, or without the theft replacement guarantee. If you are ordering, it is worth confirming you are buying from the official source.
