Sense of security
I have been worried about leaving my expensive ebike downtown while I go to the gym etc. After looking at lots of different lock options, I finally settled on the Granit Plus 470. Good reviews and the "U" part of the lock was long enough to include a wheel plus frame when locking. I already have a second lock for the other wheel. I haven't had the lock for very long, but I already feel a greater sense of security when locking up my bike. My one negative is the holder for the lock onto the frame. I tried a lot of alternatives (limited by the battery on my bike) but nothing worked due to the long "U" - which is why I wanted the lock in the first place. I have ended up strapping the lock to my carrier. Not ideal but it seems to work for me.
