## Long description

The Sourcing Bicycle Frame Lock FSBYL139220 is a frame-mounted security lock designed specifically for children's bikes. Installed on the rear triangle of the frame, it immobilizes the rear wheel to prevent rolling and offers basic theft deterrence for short stops at home, school or shops. The lock is compact and straightforward to fit on common kids' bicycle frames, and it is intended for everyday use during short-term parking.
Advantages
The frame-mounted design provides a low-profile solution that keeps the lock close to the bike, reducing the risk of snags and making it convenient for children and parents to operate. Its compact size and simple mounting system make installation quick on typical children’s frames. The lock mechanism reliably blocks the rear wheel, delivering a practical level of security suitable for brief unattended periods. Materials and construction are chosen for light weight while maintaining functional durability in everyday conditions.
Suitable for
 Children's bicycles with a rear triangle suitable for frame-mounted locks
 Short-term parking at home, schoolyards and local shops
 Everyday use where a compact, easy-to-operate lock is preferred
Key specifications
 Mounting type: frame-mounted rear wheel lock
 Intended use: children's bicycles, short-term immobilization
 Compatibility: fits typical kids’ bicycle frame geometries
 Size: compact design suitable for small frames
 Operation: simple manual locking mechanism
 Purpose: prevents rear wheel rotation to deter opportunistic theft
How to use
Position the lock body on the rear frame triangle according to the mounting hardware and secure it to the frame following the included fitting method. When parking, turn or slide the locking element into the wheel spokes so the rear wheel cannot rotate, then engage the lock mechanism. To unlock, release the mechanism and return the locking element to its stowed position. Regularly check mounting screws and the locking action to ensure the device remains secure and functional.
Usage recommendations
For effective use, install the lock on a suitable section of the rear triangle where it does not interfere with pedals, chain or brakes. Use this lock as part of a layered approach to security: combine it with supervision or additional locking methods for longer parking periods. Periodically lubricate the locking mechanism and inspect mounting fittings for tightness and wear to maintain reliable operation.
