Product Details

Overview & Technology

ABUS Ultra 410K + Cobra blends a compact, hardened-steel U-lock with a flexible Cobra Loop cable to protect both frame and quick-release wheels. The 12mm round shackle is made from specially hardened steel and is housed in a reinforced lock body engineered to resist cutting, sawing and leveraging attacks common in urban theft attempts. The unit uses a double-bolt locking mechanism to secure both sides of the shackle inside the lock body for improved twist and pull-out resistance. The included SH34 bracket (for 24–35mm tubes) secures the lock to the frame and the improved design reduces rattling for a quieter ride. The Cobra Loop cable (10mm x 120cm) gives reach and flexibility to secure wheels or accessory components, while the overall package carries a Sold Secure Silver approval for commuter-level protection.

Key Features & Benefits

Built for real-world commuting: the 12mm hardened steel shackle balances portability and cut resistance — thick enough to deter opportunistic thieves yet light enough for everyday carry. Double-bolt locking keeps the shackle firmly engaged on both sides, making twisting and prying attacks far more difficult. • Cobra Loop 10mm x 120cm: wraps through wheels and around fixed objects, extending the U-lock’s reach. • SH34 mounting bracket: clamps to 24–35mm tubes for secure on-bike transport and an anti-rattle fit. • Sold Secure Silver: tested standard for everyday urban security. • Improved anti-rattle design: reduces noise and distraction while riding.

Fit, Mounting & Compatibility

The Ultra 410K has an internal lock clearance of 170 x 230 mm (6.7" x 9"), large enough to lock many frames to typical street fixtures while still keeping the lock compact. The SH34 bracket fits seat tubes or down tubes between 24 and 35 mm in diameter (common on road and commuter bikes); check your tube diameter before installation. The Cobra cable is 120 cm long and 10 mm thick, ideal for securing wheels and accessories when used with the U-lock. Total packaged weight is approximately 3.4 lb, giving a reassuring heft without being overly cumbersome for daily commuters. Available in Black and Green colorways.

Who This Lock Is For

The Ultra 410K + Cobra is aimed at commuters, students and city riders who need reliable, portable protection for everyday stops — coffee runs, workplace parking, and transit links. Its Sold Secure Silver rating and double-bolt locking make it a strong deterrent against opportunistic theft without the bulk of heavyweight security locks. If you regularly park in high-risk areas, carry high-value components, or want the highest possible security for long-term overnight parking, pair this U-lock with a heavier-duty chain or parking in a secure facility. For typical urban use, though, the Ultra 410K + Cobra hits the sweet spot of security, convenience and price.

Frequently Asked Questions

What does Sold Secure Silver mean for this lock?

Sold Secure Silver indicates the lock passed standardized tests for resistance to common attacks at a commuter-security level. It’s a reliable rating for daily urban use, but not equivalent to the top-end Gold rating intended for prolonged high-risk scenarios.

Will the SH34 bracket fit my bike frame?

The SH34 bracket is designed for round tubes between 24 and 35 mm in diameter (seat tube or down tube). Measure your tube diameter before purchase—if your frame tubes are outside this range you may need an alternative mount or a strap-mount solution.

Can the Cobra cable replace the U-lock?

No. The Cobra cable is intended as a companion to secure wheels or accessories to the locked frame and fixed object; the U-lock provides the primary cut and leverage resistance. Using the cable alone offers far less protection than the combined system.

How many keys come with the lock and are spares available?

ABUS U-locks generally ship with at least two keys. Replacement keys and key-code-based spares are offered by ABUS through authorized dealers—keep your key code safe for ordering spares if needed.

Is this lock suitable for e-bikes or high-value bikes?

The Ultra 410K + Cobra is a solid choice for daily e-bike and mid-range bike security where convenience and moderate protection are priorities. For high-theft areas or overnight street parking of high-value e-bikes, consider upgrading to a heavy-duty locked chain or Gold-rated lock for maximum protection.

How can I minimize bracket rattling over rough roads?

Ensure the SH34 bracket is tightened to the recommended torque and mounted on a tube within the 24–35 mm range. Use the included rubber inserts (if supplied) and orient the lock so the shackle sits snugly in the cradle; periodic tightening will keep things quiet.

Buying Guide

When choosing a U-lock, prioritize shackle thickness, locking mechanism quality, and clearance size. A 12mm hardened shackle like the Ultra 410K strikes a balance between portability and resistance to handheld cutting tools. Verify the internal clearance (170 x 230 mm here) is sufficient to lock your bike to common street fixtures. For full protection, pair a U-lock with a secondary cable or chain to secure wheels and accessories. Check mount compatibility (SH34 fits 24–35 mm tubes) and consider color and weight for everyday carry—light enough for daily use but heavy enough to act as a deterrent.
