Mengshen bike lock with remote and 115dB alarm, Black, IP55 weather-resistant 10mm cable for men

Mengshen's bike lock is a weather-resistant 10mm steel cable lock with remote control, four-digit password and a 115dB anti-theft vibration alarm for versatile outdoor security.

Whether you leave a bicycle, scooter, stroller or toolbox unattended, this lock combines a flexible steel cable with dual unlocking methods and an audible alarm to deter tampering. Built to resist rain and everyday wear, it supports remote control operation up to 40 meters, programmable sharing with multiple remotes, and a four-digit code option when you don't want to use a fob.

How does the alarm protect my bike from theft attempts?

The Mengshen lock includes a built-in vibration sensor that triggers a 115dB alarm if motion, cutting attempts or disassembly are detected. A loud, sudden siren draws attention and discourages thieves, giving you time to react or alert others nearby.

• 115dB alarm for immediate local deterrence
• Sensors activate on movement, cutting and tampering
• Alarm continues until the unit is disarmed

What are my unlocking options and how do I share access?

Unlocking is available two ways: with the remote control or via a 4-digit numeric code, so no key is required. The remote has an effective range up to 40 meters, and you can program up to eight remotes per lock for family or shared use.

• Remote control unlock with 40m practical range
• 4-digit password offers 256 possible combinations
• One lock supports up to 8 remotes; one remote can pair to many locks

Is this lock suitable for outdoor use and different weather conditions?

This model carries an IP55 rating which protects against dust ingress and water spray, making it suitable for typical outdoor exposure. The steel cable and sealed electronics reduce the risk of rust and moisture-related malfunction under everyday rainy conditions.

• IP55 splash and dust resistance for outdoor durability
• Working temperature range approximately -10°C to 60°C
• Corrosion-resistant cable construction for long-term use

What should I know about power and maintenance?

The lock runs on three AAA batteries; the unit signals low battery with a flashing LED and the remote’s range will shrink when its battery is weak. Regular battery replacement and occasional cable inspection keep the alarm and locking mechanism reliable.

• Powered by 3x AAA batteries (lock) with low-battery LED warning
• Remote shows reduced function when its battery weakens
• Inspect cable and housing periodically for wear or damage

Who this is for: the Mengshen Bike Lock suits commuters, apartment dwellers and anyone who needs a flexible, visible deterrent for outdoor valuables. It’s ideal for cyclists, scooter owners, parents using strollers, and people securing gates, toolboxes or sports gear—any situation where a compact cable lock plus an audible alarm and remote access improve everyday security.
