Bikerumor noted that the Litelok X1 Plus adds nearly 60mm of length to the popular X1 model, creating a lock specifically designed for bulky e-bikes and cargo bikes while retaining its angle-grinder-resistant Barronium armor. Thebestbikelock found that this ceramic composite layer turns the tables on thieves by rapidly wearing down cutting discs, making it one of the most practical high-security options available despite not being the absolute thickest in class. Cyclingelectric highlighted the lock's ease of use and secure mounting system as key daily benefits, though they cautioned that its 1.7kg weight is a factor for commuters who prefer to carry their gear. While biketoeverything praised the extended reach for locking multiple bikes or securing helmets, reviewers consistently noted that the premium cost and added heft are trade-offs for this specific geometry.
- — Barronium composite armor layer actively wears down angle grinder discs, significantly increasing attack time compared to standard U-locks.
- — Sold Secure Diamond and ART 4 rated for the highest levels of pick, drill, and bolt-cutter resistance.
- — Extended shackle length (255mm) accommodates larger e-bike frames, cargo bikes, and allows locking two bicycles together.
- — Weight of approximately 1.9kg (4.2lbs) is heavier than standard U-locks, making it less ideal for carrying in a backpack.
- — The lock is heavy and can be difficult to carry in a backpack.
