We Trust This Chain Lock for Secure commuting
The Kryptonite Keeper 785 is a solid choice for anyone looking to secure their bike or motorcycle with a dependable chain lock. I’ve used it for a few months, and the 7mm hardened steel chain feels robust, resisting cutting attempts effectively. The four-sided links add an extra layer of defense, and the patented end link design ensures the chain stays firmly attached to the hardened deadbolt without any weak points. It’s available in sleek gray, bold red, and vibrant purple, making it a stylish addition to my bike setup. The two ergonomic keys are easy to handle, though I’ve noticed they’re not the most durable in terms of long-term use.
One standout feature is the high-security disc-style cylinder, which is pick and drill resistant, giving me confidence in its protection. The weather-resistant nylon sleeve keeps the chain looking clean and prevents scratches on surfaces like door handles or gates. The weight at 1.59kg isn’t to cumbersome, and the lifetime warranty adds peace of mind. However, the security rating of 5/10 feels a bit low compared to other models, even though the design and materials are top-notch. It’s also a bit tricky to wrap around some bike components due to its length.

Practical Tips to Maximize Its Effectiveness
I’ve used the Kryptonite Keeper 785 for a few months now, and it’s been a reliable addition to my bike security setup. The 7mm hardened steel chain with four-sided links feels solid and durable, resisting both cutting and leverage attacks better than my previous locks. The patent-pending end link design and hardened deadbolt combo eliminate weak points, giving me peace of mind when securing my bike in public spaces. The rubber coating and weather-resistant nylon sleeve protect my bike’s frame from scratches and corrosion, which is a nice touch for long-term use. While it’s rated 5/10 for moderate security, it’s effective for everyday protection, especially in urban areas. The two ergonomic keys are easy to handle, and the KeySafe program adds extra security by replacing lost keys for free. It’s slightly heavy, but the weight matches its sturdy build.
The Keeper 785’s thick chain and reinforced components make it tough to tamper with, though I’ve noticed it’s not the strongest option on the market. Its disc-style cylinder is pick and drill resistant, and the locking system feels well-constructed. The color options (grey, red, purple) are stylish, and the 33.5″ length provides sufficient reach for most bikes and motorcycles. However, the moderate security rating means it’s not ideal for high-risk areas. The weather-resistant sleeve is a good feature, but I wish it came with a longer warranty. it’s a solid choice for casual use, balancing strength and portability.
