Guessing it's quicker to cut through the metal that the bike is locked to.
Hiplock D1000 and Squire D16 MAX were the best ones they tested. Hiplock gold superbright punched above its price category.
My Kryptonite New York didn't hold up as well as I'd have hoped, but those 2 D locks above cost more then the bike I use it on.
Where is work?
Yes, it's only as secure as what it's locked to. Unfortunately e-bikes are very desirable to thieves and they can be shameless in their theft attempts.
get a really thick motor bike chain and good lock.but what would be the best lock to leave it all day?
