Best Bike Lock for Electric Bike: Top Picks That Stop Even Sneaky Squirrels

25

Electric bikes are becoming a popular way to get around town. They go faster than regular bikes and cost more, which means they are also a bigger target for thieves. That’s why choosing a strong bike lock is important if you want to keep your electric bike safe.

Bike locks come in many types, like U-locks, folding locks, and chain locks. Each kind has its own strengths, but electric bikes often need thicker or more secure locks because they weigh more and are worth more money. Over time, bike locks have become stronger and harder to break, using materials like hardened steel and advanced locking systems.

When picking the best bike lock for an electric bike, it’s important to look at the lock’s material, weight, and size. The lock should be tough enough to resist saws or bolt cutters, but not so heavy that you don’t want to take it with you. A lock’s security rating and whether it fits around your frame and a solid object also matter. We spent hours researching and testing the top bike locks to find the ones that can really keep your electric bike protected.

5 Best Bike Locks for Electric Bikes

We know that keeping an electric bike safe is a top priority for most riders. Our team has tested and compared several options to find locks that offer reliable protection and are easy to use. In the list below, you’ll find the bike locks we trust most for securing an electric bike.

1. Kryptonite Evolution Mini-7 U-Lock with Cable

This lock offers sturdy security for most e-bike owners who want an easy-to-carry lock with extra protection for wheels and accessories.

Pros

• Durable shackle provides confidence against cutting tools
• Compact design fits well on different bike frames
• Extra cable helps secure more than just the frame

Cons

• U-lock size limits what we can lock the bike to
• Mounting bracket can loosen over time
• Cable might not deter determined thieves

When we attached the Kryptonite Evolution Mini-7 to our electric bike, we noticed how solid the shackle and body feel in hand. The steel seems thick enough to hold up against basic attacks, and using the double deadbolt gave us peace of mind when leaving the bike downtown.

The bundled cable is long and flexible enough to wrap around a front wheel or even a helmet, which makes it easier to protect more than just the frame. We found the included FlexFrame-U bracket mounts easily to our e-bike, though it did take some time to figure out a spot that didn’t interfere with pedaling.

Locking and unlocking proved quick with the large ergonomic keys, especially the LED-equipped one during late-night stops. Like many mini U-locks, the opening is tight, so finding the right pole can sometimes be tricky. The sliding dust cover helped keep grit out, so the lock stayed smooth even after several rainy rides.

For riders who want dependable security without adding much weight, we think this Kryptonite Evolution Mini-7 U-Lock with Cable is one of the most practical options available.

2. Kryptonite Fahgettaboudit Mini U-Lock

This lock is a reliable pick for anyone who values serious security for their electric bike.

Pros

• Built to withstand tough attacks
• Three ergonomic keys, including one with a light
• Compact and easy to store

Cons

• Heavier than most bike locks
• Small size limits what you can lock to
• Dust cover feels a bit flimsy

We recently put the Kryptonite Fahgettaboudit Mini U-Lock to the test, and right away, its solid build stood out. The 18mm steel shackle looks and feels sturdy. We felt confident locking up our e-bike, even in busy areas. It doesn’t budge against regular tools or quick attempts to break it.

Using the lock is simple. The keys fit smoothly in the cylinder, and having a light-up key helps when it’s dark. Three keys are a nice touch, since it’s easy to misplace one. The whole lock is coated to prevent scratching our frame, which is especially useful for new or expensive bikes.

Weight is the biggest drawback. Carrying it around isn’t the most convenient—it’s heavy for a compact lock. Its small size means we have to park close and choose racks carefully. The sliding dust cover does help protect the keyhole, but it feels like it might break off if we aren’t gentle.

Overall, the Kryptonite Fahgettaboudit Mini U-Lock is a strong choice if we want peace of mind and durable protection, especially when bike theft is common. It’s not the lightest or most versatile lock, but as far as pure security goes, we think it does the job very well.

3. FoldyLock Forever Folding Bike Lock

This is one of the toughest and most reliable locks we’ve used for keeping electric bikes secure in public spaces.

Pros

• Top-tier security with solid metal links
• Folds for easy carrying and storage
• Quiet ride with a sturdy mount

Cons

• Noticeably heavy compared to smaller locks
• Limited length for locking up to larger objects
• Can take time to align and lock quickly

Out on busy city streets, the FoldyLock Forever quickly stood out for its serious security. The thick, hardened steel plates felt solid, and we had real peace of mind leaving our e-bike chained up while we ran errands or stopped at a cafe. It’s clear this lock means business—nothing about it feels cheap or flimsy in use.

Mounting was straightforward. The included case attaches right to our bike’s frame and kept rattles almost completely silent, even over bumps. Having the lock fold down so compact makes it simple to stow on the go. On the downside, we did notice the lock is heavier than you might expect, so every ounce counts if you’re carrying it by hand.

During use, the length is enough for most racks or posts, but you might struggle if you need to wrap around both wheels and a thick pole. Still, for day-to-day use in town, we found this lock strikes a balance between strong theft protection and practical portability.

For anyone who wants a solid, trustworthy option for urban and campus environments, we feel FoldyLock Forever brings true peace of mind. If you can handle a bit of extra weight and don’t need to lock up to very large objects, this one is hard to beat for protecting your e-bike investment.

4. OKG Ultra Security Chain Lock

If you’re looking for heavy-duty protection for your electric bike, this lock is one of the most secure options we’ve tried.

Pros

• Extremely tough chain that resists cutting and leverage
• Flexible cinch loop design makes locking up easier
• Durable cover protects both the lock and your bike

Cons

• Very heavy to carry around daily
• Bulky size may be hard to fit in small bags
• Lock can be a little sticky to open at times

After using the OKG Ultra Security Chain Lock, we immediately noticed its sheer weight and solid feel. The chain is thick and tough—much harder to cut than most others we’ve tested. The triple heat-treated manganese steel gives us confidence leaving our e-bike locked up, even in busy areas.

The cinch loop is a big help. We found it easier to lock the bike tightly around posts or racks, and the length means you can secure both wheels if you plan ahead. It takes more effort to move around because it’s quite bulky, but the included sleeve keeps our bike’s frame from getting scratched.

Carrying this lock is probably the main drawback. The weight adds up if you’re tossing it in a backpack every day. We also had to wiggle the key a bit to unlock it a few times. Still, for peace of mind, we think this is worth it for anyone parking an expensive e-bike in public.

5. ABUS Granit Super Extreme U-Lock

For e-bike owners who want maximum protection and aren’t concerned about extra weight, this ABUS lock is a strong choice.

Pros

• Withstands angle grinder and cutting attempts much longer than typical locks
• Solid rack mount makes carrying the lock convenient
• Key cylinder offers strong defense against theft and picking

Cons

• Heavier and bulkier than most bike locks
• Locking can feel a bit finicky and requires careful alignment
• Higher cost compared to standard options

We found the ABUS Granit Super Extreme U-Lock to be tougher than anything else we’ve tested this year. After several tries to cut through it (using beginner tools and common saws), it barely showed any marks, which speaks to its special carbide blend and strong steel design. That’s real peace of mind for expensive e-bikes.

Fitting the lock to our bike was easy thanks to the USH2500 rack mount—no clunky rattling on our ride. However, there’s no getting around the size and weight. It’s nearly four pounds and not small, so it’s best suited for riders who value security over portability.

In everyday use, the lock felt extremely sturdy, but sometimes it needed a firm push and careful lining up to close smoothly. We know the price is on the high end, yet compared to the potential cost of a stolen e-bike, it feels justified for those who demand top-tier security. The included keys and easy-to-use code card for spares are handy touches.

Overall, the ABUS Granit Super Extreme stands out for those who store expensive e-bikes in high-risk areas and don’t mind hauling a robust lock daily.

Buying Guide

When we choose a lock for our electric bike, security is the first thing we look at. Bike thieves often target e-bikes because they are valuable. A strong lock can make a big difference.

Types of Locks

Lock Type	Security Level	Portability
U-Lock	High	Medium
Chain Lock	High	Low
Folding Lock	Medium	High
Cable Lock	Low	High

U-locks and chain locks offer more protection. Cable locks are easy to carry but usually less secure.

Key Features to Consider

• Material: Hardened steel is harder to cut than standard metal.
• Locking Mechanism: Disc detainer or combination locks add extra layers of security.
• Size and Weight: We balance portability with strength. Lighter locks are easier to carry but may be less durable.
• Weather Resistance: Rust-resistant coatings help a lock last longer and work better in rain or snow.

We also check if a lock offers frame protection to avoid scratching our bike. Rubber coatings are useful for this.

Ease of Use

A lock needs to be simple to open and close. We prefer options with smooth key actions or easy-to-set combinations. Fumbling with a difficult lock can be frustrating, especially in busy areas.
