Bike Size Charts

BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Bottom line

The ABUS GRANIT XPlus 540 is renown for being tough. Sold Secure gave it a ‘Diamond’ rating for bicycle security, which means it withstood their most rigorous thievery tests. But like all locks, it could not defeat the angle grinder. While one tester claimed it took only 35-40 seconds to bust, other reported times are closer to 2.5 to 3 minutes. It’s light, compared to other locks that match its resistance. Both arms lock. It comes in two sizes and with two types of mount. While a few folk reported seizing and failure issues, for the most part it proved to be a high-quality option. The not-low price reflects this.

One of the cleverest D-lock designs ever. The state-of-the-art mechanism beat our lock picker. It outlasted our corrosion test. It stripped the standard saw blade, and took over 2 minutes of cutting with tungsten and 4 minutes with a power grinder.

ABUS GRANIT XPlus 540 D-Lock Review

Even after years on the street, GRANIT XPlus 540 is still the benchmark for shackle-style security. It’s a portable weight, too, but it’ll leave your wallet a lot lighter.

ABUS GRANIT XPlus 540 U-Lock Review

A high-quality lock. When it comes to high security, this is about as lightweight as it gets. A great deterrent if you’re locking up in a mid to high-crime area. We felt confident in urban environments. This lock lasts a long time.

U-Lock ABUS GRANIT XPlus 540 – Field Report [German]

A high-quality, very secure and well-made bicycle lock, which more than meets all of our requirements in the areas of practicality and security. It is very easy to transport but can reach its limits when the connection points are too wide.

ABUS GRANIT XPlus 540 Review – U-Lock [German]

This U-lock made a solid impression on us. Operation is simple and uncomplicated. The bracket loses a few points with us. You can only get the key out of it by unlocking it.

All the tools had a hard time with the GRANIT. Despite the massive impact of violence, it showed only minor damage and could still be used without any problems.

Abus GRANIT X-Plus 540 Bike Lock Picked

We just got this open, so it isn’t too hard to pick if you have the right tools, but I do think it’s certainly enough pick-resistance for securing a bike on the street.

ABUS GRANIT XPlus 540 Blind Pick Out the Packaging

That’s probably a really s*** time but that’s first-take. That’s not practiced, not seeing the key.

ABUS GRANIT XPlus 540 – U-Lock Test [German]

How difficult or easy is it to crack a bicycle lock and how long does it actually take? We’ll start with the ABUS GRANIT Xplus 540… It is kaput. But did it take a really long time? 3 minutes and 24 seconds.

ABUS GRANIT 540 Bike Lock – Picked With a Customized Tensioner for the Sparrows Pick (Eng Subs) [Spanish]

It is a very difficult pick that has taken me quite a bit of practice to achieve in this time. A very, very complex opening. Each disc has two false gates and one true gate, the location of which is completely random.

U-Lock ABUS GRANIT XPlus 540 [Polish]

Unfortunately, with a cordless angle grinder, you can cut through it in less than a minute. You need to cut 2 arms. The only positive is that there will be some noise.
