UKASE MAX Ebike U-Lock – Heavy-Duty Anti-Theft Shackle Lock

Lock up with confidence. The UKASE MAX is a heavy-duty U-lock (shackle lock) built to resist the most common attacks, with a dual-bolt mechanism that secures both sides of the shackle and an anti-pick, anti-drill cylinder. A great everyday lock for securing your ebike at home, at work, or around town.

• Dual-bolt locking secures both sides of the shackle for high pull resistance
• Z-Key cylinder with BumpBlok technology resists picking, pulling, and drilling
• 11mm reinforced ultra-hardened crossbar
• Protective rubber coating resists scratches and adds durability
• Includes 3 laser-cut keys and a quick-release mounting bracket
• Shackle: 4.53" x 9.06" (115mm x 230mm), 11mm diameter

Want extra reach to lock your wheels too? See the UKASE MAX with cable. Prefer a flexible chain? See the ChainKASE X-TREME chain lock. Need to get around a wide rack or fat post? The folding Link Lock opens to 34". Locking more than one bike at a time? The 7-foot ChainKASE combination lock is long enough to chain two or three together.

This is the lock we recommend to most riders, and the least expensive one we sell. Before you spend more, go look at the rack you actually use: a standard staple rack takes this fine, and only wide loops, thick posts, and improvised anchors are where a 9-inch shackle runs out of room. Our ebike lock buying guide works through that decision in full.
