Bike alarms have come a long way since the invention of the bicycle itself. Early bicycles did not have any sort of security measures on them, making them easy targets for theft. As bike riding became more popular in the late 19th and early 20th centuries, people began to realize the need for security measures to protect their bicycles from theft.

The first bike alarms were simple mechanical devices that attached to the bicycle frame and sounded an alarm if the bike was moved or tampered with. These early alarms were not very effective, as they were easily triggered by wind or other environmental factors, causing many false alarms and annoying passersby.

In the 1950s and 1960s, electronic alarms started to become more popular. These were more effective at detecting tampering with the bike, but were still prone to false alarms and could be easily disabled or tampered with by thieves who knew what they were doing.

In the 1980s and 1990s, bike alarms began to incorporate more advanced technology, such as motion sensors and microprocessors. These advancements made bike alarms more effective at detecting when a bike was being stolen, and reduced the number of false alarms.

Today, bike alarms are available in a variety of styles and levels of complexity. Some are very basic and rely on simple sensors to detect movement or tampering, while others are more advanced and incorporate GPS tracking or other features. Many bike alarms are designed to be weatherproof, making them durable and effective in all types of weather conditions.

One of the most popular types of bike alarms today is the heavy duty, weatherproof alarm with a 130db siren. These alarms are made from strong, durable materials that can withstand the elements and resist tampering, making them an effective way to protect your bike from theft.

While bike alarms have come a long way since the early mechanical devices of the 19th century, they still remain an essential tool for anyone who wants to protect their bicycle from theft. Whether you ride for fun or for transportation, investing in a good bike alarm can give you peace of mind and help ensure that your bike stays safe and secure.

1. Weather Proof: The decision to make the bike lock weatherproof ensures that the product remains effective in any weather conditions, including rain and snow. This feature is particularly important for people who use their bikes regularly, regardless of the weather. Water can cause rust, corrosion or damage to the lock mechanism which can reduce its lifespan. By making the lock weatherproof, the manufacturer ensures that it can be used in all weather conditions, which enhances its durability and increases its value for money.

2. 130db Alarm: The decision to include a 130db alarm in the bike lock is an effective measure to deter thieves. A loud alarm is particularly effective in crowded areas where bike theft is common. The loudness of the alarm attracts the attention of passersby, who can assist in stopping the thief or alerting the authorities. It can also help to deter thieves from tampering with the lock in the first place.

3. Heavy Duty: The decision to make the bike lock heavy-duty ensures that it can withstand attempted thefts by burglars. Heavy-duty materials such as hardened steel are more difficult to cut using traditional bolt cutters, which makes the lock more challenging to tamper with. People who own expensive bikes often face higher risks of theft, and a heavy-duty lock can offer better protection against theft.

Overall, the design choices made in the manufacture of this bike lock demonstrate a focus on safety, durability, and effectiveness. The weatherproof feature, 130db alarm and heavy-duty materials increase the product's value to users, ensuring that it remains effective for a long time and keeping their bike secure against theft.
