Product Details

Overview & Technology

ABUS Granit Plus 640 is engineered as a high-security U-lock that balances resistance and portability. The lock uses a 12 mm hardened steel round shackle paired with a double-bolted lock body to resist cutting, twisting and levering attacks common in urban theft attempts. The body is constructed from lightweight alloy and engineered plastics where possible to keep weight optimized (approx. 1.8 lb shipping weight) without compromising protection. Inside, the ABUS Plus cylinder and a flat-bolt ball locking mechanism deliver superior protection against picking and provide smooth, comfortable locking and unlocking in daily use.

Key Features & Construction

The Granit Plus 640 combines proven mechanical features for real-world security: a 12 mm hardened steel shackle, a double-bolt locking system, and a precision ABUS Plus cylinder that offers high tamper and picking protection. The flat bolt ball locking mechanism reduces wobble and ensures easy engagement when closing the U. Materials and construction focus on durability and weight: the shackle is quenched and hardened steel for cut resistance, the body uses a lightweight alloy shell and reinforced internal components, and the included keys use ABUS' quality keying system. The lock ships with two keys and optional TexKF brackets that fit tube diameters 21–80 mm for flexible mounting solutions.

Fit, Size & Compatibility

Internal lock size is 150 x 83 mm (5.9 x 3.3"), ideal for securing a frame and a single wheel to most city racks and fixed objects. ABUS offers variant sizes — including a longer 230 mm shackle version — for riders who need to lock both wheels and the frame to larger posts or rails. The TexKF bracket (available on select variants) fits tubes from 21–80 mm so it mounts to most seat tubes, down tubes or rear rack mounts. Check fitment against your frame and rack: the compact Granit Plus 640 is best for road/commuter frames and urban use where a rigid, high-security U-lock is preferred.

Who This Lock Is For

The Granit Plus 640 is aimed at commuters, urban cyclists and road riders who need a dependable, theft-resistant lock that’s still carryable on everyday rides. It's an excellent choice for securing expensive road bikes, e-bikes and city commuters where opportunistic theft is a concern. If you regularly lock in high-risk areas, leave a bike overnight outside, or want top-tier mechanical protection without the bulk of oversized locks, the Granit Plus 640 delivers robust security with a practical size and mounting options.

Frequently Asked Questions

What level of security does the Granit Plus 640 provide?

The Granit Plus 640 is a high-security U-lock featuring a 12 mm hardened steel shackle, double-bolted locking and the ABUS Plus cylinder. It offers strong resistance to cutting, leverage attacks and picking, making it suitable for high-risk urban environments and everyday commuter use.

Does this lock come with a mounting bracket?

Some variants include the TexKF bracket (fits 21–80 mm tube diameters) for secure frame mounting; other variants are sold without a bracket. Check the product variant description to confirm whether the TexKF bracket is included.

Will the Granit Plus 640 fit my bike frame or rack?

The standard internal dimensions are 150 x 83 mm (5.9 x 3.3"). This fits most road and commuter frames for locking the frame and one wheel to a post. If you need more clearance, choose the longer 230 mm variant to accommodate larger objects or dual-wheel locking.

How resistant is the ABUS Plus cylinder to picking?

The ABUS Plus cylinder is a premium key profile designed for high tamper resistance and excellent protection against picking and manipulation. While no mechanical lock is completely pick-proof, ABUS Plus cylinders are among the most secure standard bike lock cylinders available.

How many keys are included and can I get replacements?

Two keys are included with the lock. Replacement keys are generally available through ABUS or authorized dealers using the lock’s key code—keep the original key card or record the key number to order correct replacements.

Is this lock suitable for overnight outdoor parking?

Yes—the Granit Plus 640’s hardened shackle and robust locking mechanism make it suitable for overnight outdoor parking in urban environments. For very high-risk areas, combine the U-lock with a cable or chain to secure both wheels and accessories.

Buying Guide

When choosing a U-lock, prioritize shackle thickness, internal clearance and the cylinder quality. A 12 mm hardened-steel shackle like the Granit Plus 640 offers a strong balance of cut resistance and manageable weight for daily commuting. Measure how you plan to secure the bike — if you frequently need to lock both wheels and frame to large posts, opt for the longer 230 mm variant. For everyday urban use, the compact 150 x 83 mm size with a TexKF bracket is often the best balance of security and portability.
