OTTO Design Works have released their new OTTOLOCK Sidekick Compact U-Lock, a lightweight secure bicycle lock convenient for the cycle commuter. The bike lock is a keyed 12mm double shackle design. For additional security, it is on offer as a bundle with OTTO’s 30″ cinch lock until 26th May.
OTTOLOCK Sidekick Compact Bicycle U-Lock

The OTTOLOCK Sidekick Compact U-LOCK, also known as a D-Lock, is a silicone-coated lightweight bike lock for everyday use. Weighing a claimed 750g, it is 150g lighter and 240g lighter than the ABUS and Vie Velo ones I have lying around out back, respectively – both keyed silicone-coated bike U-Locks of a similar design.
It is a compact design measuring 2.75” x 5.75” (7cm x 14.5cm), capable of locking a single tube to a post or railing. The Sidekick Compact U-Lock is considered a medium security bike lock, with its double-shackle 12mm hardened steel design and anti-rotation deadbolt.

If you’re like me and can’t be trusted to keep your bike lock keys safe (I once had to saw open a D-Lock to free my bicycle), you might want to consider something a bit “smarter”. The BenjiLock by Hampton is one such bike lock, unlocked by your fingerprint.
OTTOLOCK Cinch Bicycle Lock

OTTO Design Works also offer a Cinch bicycle lock. This is designed for quick stops and protecting against opportunity theft. The smallest cinch lock at 18″ long weighs a claimed 145g. It coils to a compact 3 inch diameter, so should be pretty convenient to carry around.
