Kryptonite New-U Evolution Mini-7
Best OverallPros
- Compact shackle fits tight bike racks
- High security disc cylinder
- Includes mounting bracket
Cons
- Shackle is short for large frames
- Heavier than cable locks
The Kryptonite New-U Evolution Mini-7 is the standard for renters who need a balance of security and portability. Its 7/10 security rating comes from a hardened steel shackle and a disc cylinder that resists picking and drilling. Owner reviews consistently mention the lock's ability to deter thieves in urban environments.
The compact design is a key advantage for renters who store their bikes in tight apartment hallways or on crowded racks. The included FlexFrame-U bracket allows for easy mounting on the bike frame without tools, making it a convenient daily carry. It is not the lightest option, but its build quality justifies the weight for most city riders.
Abus Granit XPlus 540
Best Budget PickPros
- Very high security for the weight
- Lightweight and portable
- Excellent cut resistance
Cons
- Smaller shackle opening
- Key can be stiff initially
The Abus Granit XPlus 540 is a favorite among renters who want maximum security without a heavy lock. It boasts an 8/10 security rating due to its hardened steel shackle and the proprietary XPlus cylinder, which is highly resistant to picking. Owner reviews highlight its ability to withstand angle grinder attacks for a short time.
Its lighter weight makes it ideal for renters who carry their lock in a backpack or bag. The compact size is a trade-off, as it may not fit around larger frame tubes or thick posts. However, for locking a bike to a standard rack, it provides an exceptional level of protection for its class.
OnGuard Brute STD
Maximum SecurityPros
- Maximum security rating
- Thick shackle resists cutting
- Lifetime warranty
Cons
- Very heavy for daily carry
- Large size can be awkward
The OnGuard Brute STD is for renters who prioritize security above all else and have a secure place to store the lock when not in use. It has a 10/10 security rating, thanks to its massive 14mm hardened steel shackle. Owner reviews confirm that it is one of the most difficult locks to cut through with portable tools.
The main drawback is its weight and size, which makes it impractical for carrying in a backpack. It is best suited for renters who can leave it locked at a bike rack or in a storage room. The included mounting bracket helps, but the lock is still a burden for daily transport. It is an excellent choice for high-crime areas.
Kryptonite Keeper 585
Best Cable LockPros
- Very lightweight and portable
- Flexible for securing accessories
- Easy to use combination
Cons
- Low security against bolt cutters
- Not for high-crime areas
The Kryptonite Keeper 585 is a cable lock that is best used as a secondary lock for securing a front wheel or as a primary lock for low-risk, quick stops. It has a 4/10 security rating and is very light at 0.8 lbs. Owner reviews appreciate its convenience for short errands where the bike is never left unattended for long.
For renters, this lock is ideal for locking a bike inside a secure apartment building or garage. It should not be used as the sole lock for overnight street parking. Its flexibility makes it easy to wrap around a bike frame and a post, but it can be cut with standard bolt cutters in seconds.
Master Lock Street Cuff
Unique DesignPros
- Unique folding design
- Good portability for its size
- Decent cut resistance
Cons
- Pivot points can be a weakness
- Bulky when folded
The Master Lock Street Cuff uses a unique folding design that offers a compromise between a U-lock and a chain. It has a 6/10 security rating and is made from hardened steel links. Owner reviews like its ability to lock the bike to a wider range of objects than a standard U-lock.
For renters, the folding design makes it easier to store in a bag or clip to a belt loop. However, the pivot points on the links can be a potential failure point if attacked with a pry bar. It is a good middle-ground lock for renters who need more flexibility than a U-lock but want more security than a cable.
What to check before buying a bike lock for renters
Renters face unique challenges when securing a bike. You cannot drill into walls or install permanent anchors. Focus on locks with high portability and security ratings. Check the lock's weight, as you will likely carry it up stairs or in a bag. Also, consider the shackle size to ensure it fits around your bike frame and common racks.
Mistakes to avoid
A common mistake is buying a lock based on price alone. A cheap cable lock offers little resistance to bolt cutters. Another error is not securing both the frame and the front wheel. Thieves will quickly take a wheel left unlocked. Finally, avoid leaving a lock on the ground outside overnight, as moisture can cause the locking mechanism to seize.
FAQs
What is the best type of bike lock for a renter?
A U-lock or a folding lock is best for renters because they offer high security without requiring permanent installation. Cable locks are only suitable for low-risk areas.
Can I use a chain lock in an apartment?
Yes, but chain locks are heavy and can scratch floors. A U-lock is often more practical for carrying and storing in a rental unit.
How do I lock my bike in an apartment building?
Lock your bike to a sturdy, immovable object like a bike rack or a structural column. Always lock the frame and at least one wheel.
What security rating should I look for?
Look for a lock with a security rating of at least 7/10 for overnight or high-crime area parking. A 4/10 lock is fine for quick errands.
Are folding locks as secure as U-locks?
Generally, U-locks are more secure because they have fewer potential failure points. Folding locks offer more flexibility but can be pried open.
Should I get a key lock or a combination lock?
Key locks are generally more secure and reliable. Combination locks can be convenient but are easier to pick or decode.
Can I leave my bike lock outside in the rain?
It is not recommended. Moisture can cause the lock to rust or the keyway to freeze. Store your lock indoors when possible.
How do I carry a U-lock without a bag?
Most U-locks come with a mounting bracket that attaches to the bike frame. This allows you to carry the lock without a backpack.
What is the best secondary lock for a renter?
A small cable lock is the best secondary lock for securing your front wheel. It is lightweight and easy to carry alongside a U-lock.
How much should I spend on a bike lock?
Spend around 10-15% of your bike's value on a lock. For a $500 bike, a $50-$75 lock is a reasonable investment.
Our verdict
For renters, the Kryptonite New-U Evolution Mini-7 is the best overall lock, offering a strong balance of security, portability, and ease of use. If you need a lighter option on a budget, the Abus Granit XPlus 540 provides excellent protection without the bulk.
