Summary of Reviews

We have read all expert and user reviews on the SkunkLock Carbon. In summary, this is what cyclists think. Published Dec 05, 2024 by Rachel Rushing.

4 reasons to buy

One expert’s test shows the SkunkLock Carbon has good resistance to angle grinder attacks.
Owners feel that the heavy-duty look is a good theft deterrent.
The lock’s wide and long inner dimensions provide versatile locking possibilities and make it a good choice for e-bikes with chunky frame tubing.
SkunkLock provides three keys with the Carbon.

6 reasons not to buy

The Carbon doesn’t come with a mount and SkunkLock doesn’t sell one.
Several owners find the lock finicky, with the key needing to be positioned just right.
The Carbon is heavy for a U-lock, and an expert describes it as bulky and inconvenient to transport.
This lock doesn’t have a keyhole cover to prevent ingress of water and debris.
Several owners complain that the plastic on the end of the lock cylinder is fragile and breaks.
Two owners receive no reply after contacting SkunkLock regarding broken plastic pieces.

Bottom line

The SkunkLock Carbon is a large U-lock designed to resist angle grinder attacks, and an expert's test shows it offers good protection. Reviewers find the lock finicky. The large inner dimensions make it suitable for use with e-bikes with wide tubing. Unfortunately, no mount is provided or sold separately, and the high weight makes it cumbersome to carry. The Carbon also lacks a keyhole cover, and several buyers receive locks with broken plastic components. Overall, the SkunkLock Carbon is deemed a good, competitively priced option. For superior security, experts recommend Hiplok's D1000 or DX1000.

SkunkLock Carbon Review: The First American Angle Grinder Resistant Bike Lock!

Level 5 expert

… the first grinder-resistant bike lock from an American brand is a good option. It’s not the most resistant lock I’ve tested, but by forcing a thief to make at least one disc change, it passes the most important test.

Thanks to its price in comparison to much of the opposition, its weight and the good internal shackle size, the SkunkLock Carbon offers some good security.
