This review assesses the Oxford Bike D lock, examining its security features and overall effectiveness. Initial impressions suggest a robust design, featuring a hardened steel shackle and a supposedly "high-tech pick-resistant" locking mechanism. However, a thorough examination reveals several critical vulnerabilities that significantly compromise the lock's security. The review delves into the specifics of these weaknesses, providing a detailed analysis of the lock's design flaws and susceptibility to various attack methods.The findings challenge the manufacturer's claims of superior security. The review highlights the ease with which the lock can be picked, its susceptibility to a "twist attack," and its vulnerability to impact damage. This in-depth analysis will equip potential buyers with the knowledge to make informed decisions, considering the lock's limitations before investing in its purported protection. The ultimate verdict will determine whether the Oxford Bike D lock offers sufficient security for valuable bicycles.

Initial Impressions and Testing
The Oxford Bike D lock, with its seemingly robust design, initially appears promising. However, initial testing reveals some vulnerabilities. The tensioning of the first disc during picking proves awkward and prone to slippage.
The lock's mechanism is described as "high-tech pick-resistant," but the reviewer's experience suggests otherwise. The ease with which it was picked raises serious concerns about its actual security.
Features and Specifications
The lock features three keys, and markings indicating the shackle clearance size. It's advertised as having a hardened steel shackle, further emphasizing its supposed strength and durability.
The packaging also highlights a "high-tech pick resistant locking mechanism," a claim that the reviewer directly contradicts. The reviewer points out the cutouts on the key, which might be a design flaw.
Security Weaknesses
A significant vulnerability lies in the lock's design. The sharp, angled cutouts make it susceptible to the "twist attack," where the lock is twisted until it breaks. This is a common technique used to compromise this type of lock.
Another weakness is its susceptibility to impact damage. Striking the lock's long end can easily cause it to break, bypassing the locking mechanism entirely.
Mechanism and Overall Design
The reviewer expresses disapproval of the sliding bolt mechanism, which extends from the side of the lock. While this mechanism might seem secure, its placement can be a point of failure.
The reviewer analyzes the inner workings of the lock, highlighting a multi-disc cylinder mechanism and expressing their preference for a more robust design that uses a mechanism that locks bolts on either side.
Conclusion and Recommendation
The Oxford Bike D lock, despite its hardened steel shackle and advertised security features, proves easily compromised. The design flaws, specifically the vulnerability to twisting and impact, significantly undermine its effectiveness.
Overall, the reviewer does not recommend this lock for serious security needs. The ease of picking and susceptibility to physical attacks make it unreliable for protecting valuable bikes. Alternatives with more robust locking mechanisms are strongly suggested.
