4 Best Foldable Bicycle Locks in 2026
Foldable locks fill the gap between U-locks and cable locks. They are more secure than cables, more versatile than U-locks (since they can wrap around odd-shaped objects), and fold up compact enough for a jersey pocket or frame mount. Here are the best folding locks for cyclists in 2026.
1. Abus Bordo Granit XPlus 6500
The Bordo Granit XPlus is the most secure folding lock available.
The 5.5mm hardened steel bars resist cutting and leverage attacks at a level that matches many U-locks. The lock cylinder is pick-resistant and drill-resistant. It folds into a compact package that mounts on your frame with the included bracket. The 85cm length is enough to secure your frame and rear wheel to most racks. At about $130, it is expensive, but the security rating justifies the cost for expensive bikes.
2.
Kryptonite Keeper 585 Integrated Chain
Kryptonite's Keeper 585 is a folding lock with 5mm hardened steel bars and a disc-style cylinder. It folds into a compact rectangle that weighs about 1.65 lbs. The 85cm length provides reasonable reach. The price is very accessible at about $45, making it a good choice for moderate-risk parking situations. It will not stop a determined thief with power tools, but it handles bolt cutters and casual theft attempts well.
3.
Foldylock Compact
Foldylock designed their Compact to be the lightest folding lock worth carrying. At about 2.2 lbs with a 5mm hardened steel bar, it provides a reasonable security level in a package that is genuinely easy to carry. The 85cm length reaches most locking points. The mounting bracket is slim and integrates well with water bottle mounts. The key cylinder is hardened against drilling.
About $85.
4. Abus Bordo Lite 6050
If weight is your primary concern, the Bordo Lite uses 5mm aluminum bars instead of steel. This cuts the weight to about 1.3 lbs, which is remarkably light for a folding lock. The security trade-off is real since aluminum is softer than steel, but for low-to-moderate risk situations (coffee stop, quick errands), the weight savings are worth it. The frame mount is compact. About $70.
Locking Strategy
No lock is unbreakable. The goal is to make your bike harder to steal than the one next to it. Always lock through the frame, not just a wheel. If you have a quick release front wheel, either lock it too or replace the skewer with a locking one. Register your bike's serial number with local police and a service like Bike Index. For high-value bikes, consider two locks of different types since thieves carry tools for one lock type, rarely two.
