I got this set as I live in London and have lost wheels on trips when I haven’t been bothered to carry 2 or more locks. Being able to lock the bike wheel in place and only unlock it when the bike is turned upside down is invaluable. You will need an Allen key to unlock the wheel, but I always carry a spare tube, mini pump and a multi tool anyway. The Kryptonite lock is fine, but it is only sold secure silver rated, so it would be nice if Kryptonite bundled with his with a nicer double shackle lock. I use this lock as an extra lock to secure my bike overnight and would also be fine to use this when heading to short cafe stops or places where I will be staying for a few minutes but I would not use this as the primary lock when leaving unattended for 30 minutes or more.
