Excellent combination lock. I use it when cycling to the gym. Doesn't feel too heavy in a backpack.

Reasonable lock but instructions unclear
Seems like a reasonable lock. However, the instructions were poor. There was a Qr code to register the lock and no instructions or Qr code to tell me how to attach the lock to the bike or reset. After quite a bit of hunting through different advice and videos I eventually found some advice on the internet that helped. It is a basic courtesy to at least point customers at the appropriate instructions. The video of how to attach the lock that I found is quite straight forward however, the lock is too big to fit in the frame with a water bottle holder. Worth checking if you want to attach the lock to the bike. I will just put in my rucksack.

heavy but works
step-through bike necessitated putting mounts on side of downrod; works just fine, no interference with peddling. easy to lock up, easy to unlock. would buy it again

Taşıma aparatı gereksiz
MTB kullanıyorum fakat türü farketmeksizin taşıma aparatı çok mantıklı değil, bisikletin ağırlık merkezini bozacaktır. Kilitlenen yere sabitleme için çok uygun, güvenlik tatmin edici
