Comparison Table
1. ABUS Granit Super Extreme 2500
Best for: Protecting high-performance e-bikes from professional tool attacks.
This lock is built for high-risk areas where power tools are a concern. The 20 mm thick square shackle is specially hardened and uses a double-locking mechanism to prevent twisting. Its design is explicitly focused on resisting angle grinder attacks, which is a major concern for e-bike owners.
The plastic coating ensures that the lock doesn’t scratch your bike frame during daily use. It’s a heavy-duty option that prioritizes pure strength over portability. This product isn’t for riders who need a lightweight or compact lock that fits into a small saddlebag.
Pros
- Highest ABUS security level 15.
- Designed to resist angle grinders.
- Includes ABUS code card.
Cons
- Heavy due to reinforced steel.
- Limited by its rigid shape.

This lock is a solid choice for those who want a standard U-lock that feels substantial and secure. The double locking mechanism adds an extra layer of protection against force. This lock isn’t for users with very small frames that can’t accommodate a 230 mm shackle.

This folding lock uses 55 mm thick rods made of specially hardened steel to provide a high level of security. The rivets connecting the bars serve as a shield against saw blades, and the lock is flexible. It includes a rain cover.
The grippy sleeve on the rods protects your bike’s paint from damage during locking. It’s a great middle ground between a heavy chain and a rigid U-lock. This lock isn’t for riders who prioritize the absolute lowest weight, as it’s relatively heavy.
Pros
- High flexibility for locking.

The lock includes a lighted key. This chain is very robust and provides significant security for your frame. This product isn’t for those who want a lightweight setup, as the chain adds considerable bulk.

The soft coating on the rods prevents paint damage, which is ideal for high-end frames. It’s very flexible and easy to handle in daily use. This lock isn’t for those who prefer the security of a physical key, as combinations can be forgotten if not stored properly.

This lock is very easy to transport because it doesn’t require a separate bracket. This lock isn’t for those who need high-security protection, as the 6 mm chain is thinner than other heavy-duty models.

How to Choose in Sixty Seconds
Which lock type is safest?
U-locks generally offer the highest security because they’re made of solid, hardened steel and are harder to cut. For the highest risks, look for locks like the ABUS Granit Super Extreme 2500, which is designed to resist power tools.
Does the security level matter?
Yes, ABUS assigns a security level from 1 to 15 to help you choose the right protection. Level 15 is for high-risk areas and long-term parking, while lower levels are fine for quick errands in low-risk zones. Pick a level that matches your bike’s usage and the crime rate in your area.
Should I get a combination or key lock?
Key locks are often considered more secure, but combination locks are convenient because you can’t lose your key. If you choose a combination lock, make sure you can remember the code. If you’re prone to losing things, a key lock with a code card for replacements is a safer bet.
Closing
For the best overall security, the ABUS Granit Super Extreme 2500 is the top choice for its angle grinder resistance. For those needing maximum portability without sacrificing too much strength, the ABUS Bordo Granit 6500K is an excellent alternative. Check your bike frame diameter to ensure your chosen lock bracket will fit correctly before ordering.

Frequently Asked Questions
What happens if I lose my keys?
Most ABUS locks come with a code card that allows you to order replacement keys from the manufacturer. Always keep this card in a safe place, separate from your bike, so you have the necessary information if your keys go missing.
How do I know which bracket fits my bike?
Most ABUS lock listings specify the frame diameter range that their brackets support, such as the 20 – 55 mm range for the SH B holder. Measure your bike’s frame tube diameter before purchasing to ensure a proper fit. If your frame is unusually shaped, double-check the mounting instructions to confirm compatibility.
