Foldable Bike Lock AUTHOR AUL FlexGuard-8 X9 l.940mm (black)

AUTHOR AUL FlexGuard-8 X9 l.940mm (black) is a foldable bike lock engineered for on-bike convenience and everyday urban security. With a multi-segment folding construction and a total length of 940 mm, the lock folds compactly for storage on the frame and unfolds to secure frames and wheels to stands, rails, or fixed objects. The black finish offers a discreet appearance while the articulated segments provide flexibility to reach various anchor points.

Advantages

The foldable design balances compactness and reach, making it easy to carry on the bike without bulky weight. Articulated segments allow flexible positioning around different shapes of anchor points, and the rigid metal construction gives resistance to common attacks. Its length permits locking both frame and one wheel to many typical urban fixtures, and the black coating provides weather resistance and reduces visible wear.

Suitable for

• Everyday urban commuting where compact storage on the frame is preferred
• Securing a bicycle frame and one wheel to bike stands, rails, or lamp posts
• Short to medium duration stops such as shops, cafes, or transit hubs

When it may not be suitable

This foldable lock is designed for everyday urban use and provides a balance of portability and security; however, it may not offer the highest level of protection required for long-term parking in high-theft areas or for securing high-value bicycles unattended for extended periods. For maximum resistance against heavy-duty tools or determined thieves, a larger U-lock or an additional heavy chain lock would be more appropriate.

Key specifications

• Type: Foldable/folding bike lock
• Length (unfolded): 940 mm
• Construction: Multi-segment articulated metal links
• Finish: Black protective coating
• Intended use: Frame and wheel locking to fixed objects
• Carry: Compact folding for on-frame mounting or saddle-mounted carriers

How to use

Unfold the articulated segments until the required length is reached, wrap the lock around the bicycle frame and a fixed object or through a wheel, and engage the locking mechanism according to the lock’s key or combination system. Fold any remaining segments for compact storage and secure the lock to the bike using the supplied mounting bracket or an appropriate strap when not in use. Regularly check the lock for dirt and lubricate the locking cylinder as recommended to maintain smooth operation.

What to consider before purchase

• Required security level depending on parking location and duration
• Compatibility with your bike frame and preferred mounting method
• Whether the unfolded length (940 mm) is sufficient to reach common anchor points you use
• Preference for key or combination locking mechanisms

Usage recommendations

For improved security, use the foldable lock in combination with a secondary locking method (for example, a cable or small chain) to secure both wheels when leaving a bike in areas with higher theft risk. When parking, choose well-lit, busy locations and lock the frame to a sturdy, immovable object. Periodically clean and lubricate the lock cylinder and hinges to ensure reliable operation.
