## Long description

MAGNUM MGN-3101 is a U-lock designed to secure bicycles and similar personal transport in urban settings. Its compact, rigid shackle construction allows the lock to fasten frames and wheels to fixed objects such as bike racks, posts, or railings. Intended for everyday use, this U-lock offers straightforward mechanical security for short- and medium-duration stops and is suitable for commuters, students and casual riders who need a reliable physical deterrent against opportunistic theft.
Advantages
The U-lock design provides a rigid, tamper-resistant shape that reduces leverage attack vectors compared with cable locks. Its compact dimensions make it convenient to carry and mount on frames or inside backpacks. The lock mechanism is built for repeated daily operation and offers consistent closing and opening action. The rigid shackle and crossbar deliver stable clamping around frame tubes and fixed anchors, adding reliable mechanical protection during routine stops.
Suitable for
Securing city bicycles during short urban stops
Locking commuter bikes at transit hubs and workplaces
Fastening children’s bikes and small frames to fixed objects
Supplementary locking of wheel or frame in combination with additional cable or chain
Key specifications
Lock type: U-lock (rigid shackle)
Intended use: everyday urban bicycle security
Form factor: compact, rigid crossbar and shackle
Material characteristics: hardened shackle for basic resistance to cutting and leverage (mechanical design)
Operation: manual key-operated cylinder
Compatibility: fits standard bike frames and typical fixed anchors such as racks and posts
How to use
Position the U-lock so that the shackle passes through the bicycle frame and, if possible, a wheel, then engage it around a fixed, immovable object such as a bike rack or metal post. Insert and turn the key to lock the mechanism; remove the key and keep it in a safe place. When unlocking, insert the key and turn to release the shackle, taking care to pull the lock free without placing excessive force on the frame or wheel spokes. For routine use, mount the lock in a dedicated bracket or carry it in a bag to avoid damaging paintwork.
Usage recommendations
For improved security, use the U-lock to secure the frame and at least one wheel, and consider a secondary cable or chain to secure the other wheel or accessories. Choose a visible, well-lit location and fasten the lock so there is minimal empty space inside the shackle to reduce leverage attempts.
