I’ve been running TiGr bow locks for years, since ‘14 probably, and they— I have three bows, including a heavy duty prototype— have been keeping my bikes safe here in this university town.
As has been said, any lock can be defeated if the thief has the desire, so there are lots of factors which determine whether your lock gets targeted, attacked, and to what extent. I’ve never locked up habitually in the same place, for example, so that works in favor of defense. That the TiGr is still a relatively rarity and unknown to thieves also works in favor of defense, I’d think, as most people like to mitigate risk and tend to go with what they know; I don’t think thieves are substantially different except for having a higher risk tolerance. Lots of stolen bikes, but few brazenly stolen with electric grinders from outside grocery stores, it seems.
TiGr bow stows so neatly, it makes living with a lock a breeze…pun intended!:
