Bicycle Disc Brake Lock Portable Anti-Theft Alarm Electric Car Disc Safety Lock Metal 9.5 x 3.7 x 6.9 cm in Black Red Blue Green Yellow with Tip Rope for Bike and Scooter Security
Bicycle Disc Brake Lock with Alarm and Metal Body

This disc brake lock is a compact security device for bicycles, electric cars, and similar vehicles that use disc brakes. It combines a metal lock body with an anti-theft alarm function, giving riders a visible physical deterrent when parking in public or shared spaces. The lock measures 9.5 x 3.7 x 6.9 cm, so it is small enough to carry or store without taking up much room. It is available in black, red, blue, green, and yellow, and each unit includes a black tip rope. The package contains one anti-theft lock. This description covers only the details provided in the source, so no assumptions are made about waterproofing, battery life, alarm volume, or weather resistance.
Features and Construction

The lock is built around a metal body and a disc brake locking mechanism. Its small format makes it easy to transport, while the colour range allows for matching with different vehicles or personal preferences. The alarm function is a built-in part of the product, intended to draw attention if the vehicle is moved while locked.
Material and Build
The main body is made from metal, as stated in the source. This gives the lock a solid feel and a physical presence on the brake disc. The included black tip rope is a small accessory that can help with handling or visibility. No further material claims are made, and the source does not specify coatings, hardening, or resistance to cutting. The lock is designed for disc brake use and should be fitted according to the vehicle's brake setup.
Size and Practical Fit
With dimensions of 9.5 cm in length, 3.7 cm in width, and 6.9 cm in height, the lock is compact enough to fit into a bag or under a seat. It is intended to attach to a disc brake rotor, so the fit depends on the brake design of the bicycle or electric car. The small size also means it can be carried alongside other riding gear without adding significant weight. The source does not provide a weight figure, so no weight claim is made here.
Uses and Placement

This lock is suitable for everyday parking and short stops where a disc brake lock can be used. It is relevant for bicycles, electric cars, and similar vehicles with disc brakes. The alarm adds a layer of attention if the vehicle is disturbed, while the colour options make it easy to identify.
Event or Professional Use
For riders who park in busy areas, the lock provides a visible security point on the brake disc. It can be used alongside other locks as part of a broader security routine. The alarm function is built in, so no separate alarm unit is needed. The source does not specify alarm sensitivity or sound level, so these details should not be assumed. The lock is straightforward to carry and use when moving between locations.
Everyday Home Use
At home, the lock can be stored in a shed, garage, or hallway and fitted when the vehicle is left outside. Its compact size means it does not need much storage space. The metal body and tip rope are the only stated components, so care should focus on keeping the lock clean and dry. The colour options can help distinguish one lock from another in a household with multiple vehicles.
Benefits and Buying Value

The main value of this lock comes from combining a disc brake lock with an alarm in one unit. It is small, portable, and available in several colours. Because it is a mechanical lock with an alarm, it can be reused whenever the vehicle is parked, provided it is looked after and stored sensibly.
Reuse and Low Maintenance
The lock can be used repeatedly as part of a regular parking routine. To support its working life, keep it dry and free from dirt, and check the mechanism before each use. The source does not provide specific maintenance instructions, so only basic material-based care is suggested. The metal body and tip rope should be inspected for damage, and the lock should be stored away from moisture when not in use.
Why Choose This Product
This disc brake lock is a practical option for riders who want a compact, metal lock with an alarm and a choice of five colours. It includes a black tip rope and comes as a single anti-theft lock. It is suitable for bicycles, electric cars, and other disc brake vehicles. The source does not provide performance ratings, so the choice should be based on the stated materials, dimensions, and alarm function rather than unverified claims.
