From this set
The 13mm steel shackle on the Evolution Mini-7 feels incredibly solid when locking up my bike downtown.
I use the KryptoLok with the mounting bracket on my e-bike and it stays quiet and secure during my commute.
The 4-digit combination on the U-lock is easy to reset and saves me from carrying extra keys.
