I placed this ONGUARD confidently on my new and very expensive Cannondale Scalple bicycle with a Lefty Fork, that I converted to be a high performance E-bike (Electric bicycle with a top speed of about 42 mph without pedal assistance). This excellent lock is very secure and almost fool proof. I lock the bike with the "DT U-Lock" through the very expensive motorized rear rim and frame then run the "Cinch Loop (It is much longer than 4", possibly 14", maybe a typo)" cable thru the frame and front Lefty rim. For a little added security I placed an audible alarm on the the U portion of the lock that rests on the almost $500.00 lithium battery so if one moves the lock it will sound an ear piercing siren. It is Velcro-ed with industrial strength Velcro to the battery case so one must apply force to jar it and set off the alarm. After all even the best locks keep the honest, honest and only deter the the dishonest. I also added a small hidden GPS tracking system to find the smart thieves and myhot bicycle (daily transportation). Yet this protection system with the On Guard Bulldog at the center of it offers the best security that is available, It is actually more secure than Low-Jack, I just hope that someday soon the ON Guard Bulldog will come with all the features I have added to it. All said and done I love this lock and recommend it to everyone. PLEASE NOTE: if you want to steal my bike you have to get by the BULL DOG first!Read full review

Ok Lock with great mounting hardware. The insurance isn't worth a hoot. It's basically like the extended car warranty racket.
