Manganese alloy steel motorcycle U lock

Updated 2026-09-05

Featuring an 18mm anti-cut manganese alloy steel shackle, this U-lock is designed for extreme security needs. The dual-deadbolt mechanism locks both sides of the shackle into the crossbar, doubling the resistance against pulling and prying attacks, which is essential for securing expensive e-bikes, ATVs, and motorcycles.

The drill-proof and weatherproof design ensures that the locking core remains protected against both physical tampering and environmental degradation. This level of durability makes it suitable for long-term outdoor use in various climates, providing a reliable anchor point for your most valuable outdoor gear and vehicles.

Included with the lock are four keys, ensuring you have ample replacements. The compact yet incredibly strong profile makes it easy to store in a pannier or backpack while traveling. Its specialized steel composition is specifically chosen for its high tensile strength and resistance to common theft tools.
