Lock holder FISCHER 85913 for bicycles — universal black accessory

FISCHER 85913 lock holder for bicycles is a universal black plastic accessory designed to secure and carry a U-lock or chain on the bike frame. The compact mount is intended to be fitted under the saddle or to a suitable tube on the frame so that a lock remains accessible during rides while minimizing movement and rattling. The holder functions as a replacement or spare part to restore convenient transport of locks on urban, trekking, or commuter bicycles.

Advantages

The lock holder is made from durable black plastic that resists weather and everyday mechanical stress. Its universal design fits most common locks and frame geometries, enabling straightforward installation without specialized tools. By keeping the lock attached to the frame, the holder frees backpack or luggage space and reduces the risk of forgetting or losing the lock when parking the bike.

Suitable for

• Commuter and city bicycles that require on-frame lock transport
• Trekking and leisure bikes where compact storage of a U-lock or chain is needed
• Replacement or spare part needs when original lock mounts are damaged or missing

When it may not be suitable

The holder’s universal shape covers a wide range of locks and frames but may not fit unusually thick or unusually shaped U-locks and chains. Bikes with very limited space under the saddle, unusual seatpost assemblies, or integrated under-saddle storage solutions may not provide a suitable mounting location.

Key specifications

• Material: black plastic
• Mounting location: under saddle or on frame tube
• Compatibility: designed for most common U-locks and chains
• Purpose: secure and transport a bicycle lock on the frame

How to use

Position the holder under the saddle or on a frame tube where the lock can be held securely and does not interfere with pedaling or wheel movement. Attach the holder using the integrated clamps or straps provided with the product and ensure it is tightened to prevent slipping. Place the U-lock or chain into the holder so it sits firmly; verify that the lock does not rattle or contact moving parts. Periodically check the attachment points and fasteners for wear and retighten if necessary.

What to consider before purchase

• Check the cross-section and available space of your saddle underside or frame tube to ensure the holder can be mounted.
• Compare your lock’s dimensions to the holder’s opening to confirm compatibility.
• Consider whether you need additional straps or adapters for non-standard frame shapes.

Usage recommendations

For safe and quiet transport, fit the lock securely and add a soft protective sleeve around the lock if it contacts the frame. Regularly inspect the holder and fastenings for damage and replace the mount if cracks or significant wear appear.
