ABUS U-Lock Granit XPlus 540, Bike Lock with XPlus Cylinder, High Protection Against Theft, ABUS Security Level 15, Black/Grey

This is the best bike lock at this price range. Best weight to strength value. I use it for my Ebike.

great product

Love this lock, dont love the price. However, its the same price on Amazon than pretty much everywhere else..

Awesome lock, my bike has not been stolen so far.

I just simply love it. Great product, lovely seller

I am editing my review after contacting DealExperts about the issue. As you can read in my original post, I had some issues with this lock, which was very confusing, as Abus is a top-notch brand and this is one of the best locks on the market. After my beloved bike Peaches was stolen in downtown L.A., I couldnt handle another loss. Im a full-time student with 3 jobs; my friends kindly kicked in for a new bike, but it fell to me to pick out a lock. After struggling with the lock for 2 months and juggling all my jobs/school, I reached out to Amazon customer service. They said it was out of the return window timeframe and referred me to the dealer. The dealer said it was outside the return window timeframe and referred me to Amazon C.S. I went back to DealExperts and BEGGED THEM TO TAKE PITY ON ME, as Im a student with one only way to get around, my bike. For good measure, I wrote this bad review. DealExperts responded immediately with a return auth for me to give to Amazon C.S., and after a lengthy phone call with Amazon, they shipped me a new lock and it arrived in 24 hours! I still need to send the defective one back, but I just need to print the label, which is free. Im super relieved and happy. The new lock works like a dream. I would definitely do business with DealExperts again. Original Post-I was so excited about this lock. I researched extensively and decided on this one, as its as close to top of the line as it gets. But, the key has been stiff in the lock. I ride EVERY day, so this became a thing pretty quickly. I thought, NBD, its new, just needs some use. Nope. Its been 2 months, and I still have to attempt to lock it 8,9,10 times EVERY time. I try turning it around, I try wiggling. I tried bike lube. I tried everything! Now Im not sure what to do. Everything else about it is amazing. :(

Heavy, but very Secure

No lock is impossible to break, but this one comes pretty close while still being versatile. Its a good size to lock the back of my bike frame and wheel (including an electrical motor) to an adjacent rack. Also works to lock the front wheel to the frame. The key mechanism is still smooth after 1 year and a half even with exposure to rain. I use it along with another ABUS folding lock when I need a more flexible locking configuration, and my bike hasnt been stolen yet, so I guess its doing its job. If you ever need to order another key, its pretty hassle free using the given card. Allow for about 2 weeks shipping to US, so I would recommend replacing your spare immediately once youve burned through one.

This lock feels indestructible, but the key is now permanently stuck in the lock with my bike locked to a rack. ABUS will not replace the lock unless I return it to dealer where I bought it for inspection. That dealer was Amazon, and the return window is long gone. I can ship the lock to ABUS to have them inspect it and determine if a replacement is warranted, but its stuck on my bike/bike rack and even if I could get it off I would be without a lock for a few weeks. I recommend going with Kryptonite bike locks instead, as I have one of those that I purchased in 2005 that still works great 15 years later.

Still have the bike... :)
