Top! ### ⭐⭐⭐⭐⭐ Best lock for kids - easy to use *by C***R on 12 July 2023* My review compares an old Kryptonite lock, newer Hiplock DX and this Sigtuna U-lock. All other U-locks require you to hold and insert the shackle into the crossbar body while ensuring key is in correct position and twisting key at the same time to lock. This is a difficult operation for my young kids. This Sigtuna lock when unlocked holds key in crossbar body and at same time holds the dual hinges open. To lock you simply push the two halves closed, the key reverts back neutral position, the dual hinges snap closed and you pull key out. Love it! The Sigtuna key is dual sided so you don't have to worry how it goes in, unlike my single sided Hiplock keys where it only goes in one way, so annoying for the expensive Hiplock. Although more pick-proof, the disc detainer style of the Kryptonite keys are finicky to push in sometimes making locking difficult for my kids. Sigtuna also gives you three keys which is nice. I like the square cross-section design of the Sigtuna shackle, this should help a bit with twist attacks, but the crossbar body is a bit lighter than my other two locks, so thieves may still be able to steal your bike with one cut. The newest Kryptonite U-locks are probably best with it's "Pass-through" crossbar design where thieves may need 2 cuts, but those are several times the price and not as easy to use. I'm unsure the hardening quality of the shackle of my Hiplock compared to Sigtuna, but I can say the later is much thicker. Weight of my Hiplock shackle is 520g where as the Sigtuna is 880g. ## Frequently Bought Together - Bike U-Lock - Sigtuna Bike Lock Heavy Duty Anti-Theft with 4ft/1.2m Cable, Bicycle U-Lock with Sturdy Mounting Bracket for Mountain Bikes, Ebikes, Scooters - Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black - Lamicall Bike Phone Holder, Motorcycle Phone Mount - Motorcycle Handlebar Cell Phone Clamp, Scooter Phone Clip for iPhone 15 Pro Max/Plus, 14 Pro Max, S9, S10 and More 4.7" to 6.8" Smartphones --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/474780356-sigtuna-bike-locks-16mm-heavy-duty-u-lock-with-u](https://www.desertcart.tn/products/474780356-sigtuna-bike-locks-16mm-heavy-duty-u-lock-with-u) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-11*
