My only issue is with the bracket, if I'd realised the bracket was offset I wouldn't have bought it. Also the lock moves around quite a bit in bracket which rattles which is annoying! Also because the bracket is offset it doesn't sit snug within your frame or behind your seat, it sticks out a good two inches. Currently trying to source a better bracket for it. Review: Excellent lock. Quite difficult to use - HEAVY. Requires REGULAR oiling. - Excellent lock. Very heavy, thus not very suitable for women. Even I struggle to use it. Hopefully that makes it good protection (I wish). It's difficult to use. Doesn't go in or out as easily as one would expect. Key is non regular key, has complex 2d dual pattern, which should make it more difficult to brake in. It requires REGULAR oiling, otherwise, within 2 weeks, it's not possible to insert key. Now. Usual stuff about protection level. As all other locks, this can be killed within seconds by proper tools and technique. Lock itself is probably good 'protection'. Cutting thru with disc, standard, within like 10-20 seconds. Braking thru with making leverage and braking the U shape, harder and longer, due large U distance (longer the distance between parts, more difficult to brake it with crowbar/ other lever). That's probably the most sturdy set I've had. ## Features - Sturdy and Durable: Heavy duty bicycle U lock is made of hardened max-performance steel shackle resists cutting and leverage attacks.size(L,W):28cm x 16cm - More Safe: Mountain bike locks sing zinc alloy lock core and complex serpentine key slot to against various means of theif effectively. - Increased Protection: Bike U-lock combin with steel loop cable can provide increased protection for securing front wheel or accessories. With 4ft high-quality steel cable allows greater locking flexibility.

It has to stay on one side of the bar and keep it in mind because of that it was not suitable for attaching it to the main frame as it just do not stay in the middle. Thats why I give 4 stars. Not practical bracket always stays on your way, but I like the rubber coating for protecting your bike from scratches --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/145943906-bicycle-u-shackle-lock-heavy-duty-d-lock-high-security](https://www.desertcart.pl/products/145943906-bicycle-u-shackle-lock-heavy-duty-d-lock-high-security) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-02*
