Kryptonite New York Fahgettaboudit U-Lock (9US)

The Kryptonite New York Fahgettaboudit is a heavy-duty U-lock built for securing motorcycles, scooters and bicycles in high-theft areas. It sits at the top of Kryptonite's New York security range, using a hardened steel shackle and crossbar rather than the lighter constructions found on commuter-grade locks.

It suits riders who park on the street, in shared garages or at unattended stations and want a substantial physical deterrent. As with any high-security U-lock, the trade-off for the extra material is weight and bulk, so it is best matched to overnight or long-stay parking rather than constant carry.

• Part of Kryptonite's New York Fahgettaboudit range, the brand's high-security U-lock tier
• Hardened steel shackle and crossbar construction
• Suited to motorcycles, scooters and bicycles parked in high-theft areas
• Keyed U-lock design for securing the machine to a fixed anchor point

Lock the shackle around a fixed, immovable anchor and through the frame or wheel, keeping the lock body off the ground where it can be attacked with leverage.
Fill as much of the internal space as possible so there is little room for tools to be inserted inside the shackle.
Keep the key hole clean and covered where a dust cover is fitted, particularly if the lock lives outdoors.
Lubricate the cylinder periodically with a dry PTFE or graphite-based lubricant; avoid heavy oils and general-purpose sprays, which attract grit.
Rinse off road salt, sand and mud with fresh water, then dry the lock thoroughly before use to limit corrosion.
If the key turns stiffly, clean and lubricate the cylinder rather than forcing it, and never insert a key that is bent or damaged.
Store spare keys somewhere separate from the bike, and record the key number in case a replacement is needed.
Carry the lock in a bag, pannier or dedicated bracket rather than looped over handlebars or a rack, where it can bounce and damage paintwork.
