Folding locks combine portability and security. Learn what to look for and how to pick the right one for your bike.
Quick answer
A folding lock is a strong, portable alternative to a U-lock or chain. For most riders, the ABUS Bordo 5700 series offers the best balance of security and everyday carry convenience.
Why choose a folding lock over a U-lock or chain?
Folding locks pack the rigidity of a U-lock into a shape that folds flat, making them easier to stow in a bag or mount on a frame. They are lighter than most chains of similar security and do not rattle as you ride. The trade-off is that folding locks have more moving parts (the riveted joints), which can wear over time, and they generally offer slightly less brute shear resistance than a thick U-lock.
Key factors to consider when buying a folding lock
Bar thickness and material are the main security indicators. Most quality folding locks use hardened steel bars. The ABUS Bordo 5700 and Bordo Lite 6055 both use 5 mm steel bars, but the 5700 series has a heavier construction for higher security. Weight and folded size matter if you plan to carry the lock in a jersey pocket or small bag. The Bordo Lite 6055 weighs only 400 g, while the 5700 Key version comes in at about 830 g. Also consider the locking mechanism: key or combination. Keys are generally more reliable over time, but combinations eliminate the risk of losing a key.
Decision rules for choosing a folding lock
- Security level needed: If you park in a high-theft area for long periods, choose a lock with thicker bars (5 mm or more) and a higher security rating. The ABUS Bordo 5700 series is a solid choice. For quick stops in low-risk areas, a lighter model like the Bordo Lite 6055 is sufficient.
- Carry method: If you want to slip the lock into a jersey pocket, look for the lightest option. The ABUS Bordo Lite 6055 Key Folding Lock weighs only 400 g and is small enough to fit. If you prefer a frame mount, the 5700 series includes a carrying bag that attaches to your bike.
ABUS Bordo Lite 6055 Key Folding Lock - Key vs. combination: Choose a key lock if you want the most reliable mechanism and don't mind carrying a key. Choose a combination lock if you want to avoid keys entirely and are comfortable setting and remembering a code. The ABUS Bordo 5700 Combination is a great keyless option. If you share a bike with family or coworkers, a combination lock lets everyone use it without needing extra keys.

- Riders who want more security than a cable lock but less bulk than a heavy chain
Not for
