- Make sure this fits by entering your model number.
- GERMAN ENGINEERED 14MM HARDENED STEEL- Abus uses only the highest grade, special temper hardened steel for its components and has been doing so since 1924. These decades of experience and commitment to quality have made Abus one of the premiere lock manufacturers, keeping people’s bikes safe across the globe.
- INDUSTRY LEADING CORROSION RESISTANCE- Don’t open yourself to easy thefts by using a degraded and corroded lock. Abus’s corrosion resistant coating and through-body shackle technology featured on the U-Lock keeps your bike secure for years.
- LIGHT WEIGHT AND COMPACT- The U-Mini 40 lives up to its name by wrapping an incredibly strong, durable and secure bike lock into a small unit that can easily fit in your back pocket, won’t weigh your bag down in transit, and easily mounts to your frame.
- ABUS PREMIUM CYLINDER PROTECTION- The general idea of a bike theft is that someone came with bolt-cutters and after slicing and dicing through your bike lock, they took off on your ride. This isn’t the only form of attack though and this is why in conjunction with the absolute best torsion resistance, Abus offers you their Premium Cylinder technology that protects the entire locking keyed mechanism from lock picking.
- DOUBLE BOLTING SHACKLE- The Bolting Mechanism locks in two places, offering an elite level of security and doesn’t leave any weak spots in the armor for a bike thief to take advantage of. The U-Mini 40 makes it incredibly simple for you to ride where and when you want without fear of what could happen to your bike when you’re not rolling. The Soft Touch Coating even ensures that your paint job won’t get the slightest hint of a scuff.
