    I think this is currently doing a great job. It is easy to attach to your bike while riding and does not slide or rattle around on the frame much. It also seems like a heavy lock that would be difficult to get through. My only complaint is that the locking mechanism could be improved and is currently a bit annoying. You have to hold the key in the unlocked position to insert the bar before locking. An auto lock mechanism would be great

    Works well and appears as sturdy as my last $50 lock. Comes with two keys as well as a mounting clip to fit securely on your bike. Great deal.

    The Master Lock 8170D U-Lock offers straightforward, reliable bike security at an affordable price. Its 6-1/8 inch width and 8-inch shackle length provide ample room to secure both the frame and wheel to most bike racks. What stands out is its user-friendly design. The included carrier bracket is alright but I typically just throw it in a bag. Removing and applying the lock is quick and hassle-free, which encourages consistent use. The vinyl coating is a nice touch, protecting both the lock and your bike from scratches.

    The Master Lock Black Bike Lock with Key impressed me with its solid construction and sense of security. The lock’s quality was apparent from the first use. While I haven’t had the unfortunate need to test it against actual theft attempts, I felt confident in its ability to deter thieves. The lock felt very sturdy, and I often tried to pull it apart with my hands to test its strength, finding it very resistant to force.

    The lock features an integrated disk keyed locking mechanism, which was straightforward to use, though I’m not entirely familiar with the technical details of this mechanism. However, each time I used the lock, it required a bit of effort to lock and unlock efficiently. This could be due to the lock’s solid construction, which, while providing security, also made it slightly cumbersome to operate.

    The description mentioned a vinyl coating, which I’m not entirely sure about in terms of its function or appearance. However, the lock looks well-made and durable. Its weight is significant, which is a positive aspect in terms of security but made it inconvenient to carry in a backpack. Instead, I opted to hang it on my bike during rides, avoiding additional weight on my back, which could affect my riding comfort and speed.

    Overall, this lock represents a good investment, particularly compared to cheaper alternatives I’ve used in the past, such as those from Dollarama. It offers a higher level of security and build quality, making it a valuable addition to my biking gear.

    In a world of burgeoning e-bike thefts, the Master Lock 7.25″ U Lock offers an affordable solution to deter opportunistic thieves. For its price, it serves its purpose well, acting as a visual deterrent for anyone hunting for an easy steal. Its affordability, therefore, shouldn’t be dismissed outright.

    However, its performance against more determined or skilled thieves is a different story. The lock is unfortunately susceptible to picking and cutting. This vulnerability raises some concerns about its effectiveness as a standalone security device for your e-bike, especially in high-theft areas.

    That said, when used in conjunction with a sturdier lock, such as the Kryptonite Evolution 1090, it plays a role as an excellent secondary security measure. This combination has proven successful in my case, having effectively safeguarded my e-bikes in an area known for frequent thefts.

    In conclusion, the Master Lock 7.25″ U Lock is a budget-friendly choice for those looking for an additional layer of security. Its strength may not lie in its ability to withstand dedicated burglary attempts, but as a secondary lock that enhances the overall security of your bike, it certainly does the trick. Just remember that with locks, you often get what you pay for, and this one is no exception.
