U-lock ABUS 37887 bike lock Black

The ABUS 37887 bike lock Black is a compact U-lock designed to secure bicycles in urban and suburban environments. Constructed with hardened steel shackle and a protective outer coating, the lock measures 109 mm in width and 230 mm in height and weighs 1.16 kg. Supplied with two keys, it offers a straightforward mechanical locking solution for everyday use on streets, at stands, or in shared parking facilities.

Advantages

This U-lock combines a small footprint with solid mechanical resistance to cutting and leverage attacks thanks to its hardened steel construction. The black protective coating helps prevent scratches to the bike frame and reduces corrosion exposure. At 1.16 kg the lock balances portability and security, making it practical for regular riders who need a reliable lock without excessive bulk. Two supplied keys reduce the risk of being left without access when one key is misplaced.

Suitable for

• Securing commuter and city bicycles at racks and bike stands
• Short- to medium-term parking in urban environments
• Locking a bike frame to fixed objects such as poles or railings
• Use with lightweight accessories where a compact yet robust lock is needed

How to use

Position the U-lock so the shackle closes around the bicycle frame and a fixed object, ensuring the frame and at least one wheel are secured where possible. Insert the shackle into the lock body and turn the key to engage the locking mechanism. Remove the key and keep it in a safe place; store the spare key separately. When removing the lock, insert the key and turn it to retract the shackle before pulling the lock free. Regularly check the keyway for debris and lightly lubricate the mechanism with a dry lubricant if needed to maintain smooth operation.

Usage recommendations

For best results, use the lock in combination with additional security measures (such as a cable for the front wheel or a secondary lock) when leaving a bicycle unattended in high-risk areas. Always secure the lock through the frame and a solid anchor point, keep the lock off the ground to reduce leverage on the shackle, and store spare keys separately to avoid lockouts.
