Love it!!

Loving my scooter so far. Put about 100 plus miles on it and still running strong! The tools they sent weren't the correct sizes but l luckily I did have my own tools no big deal. Assembly was easy. Wish braking was a little better but I give it a 8/10 on braking. I ride it every weekday for work and it's been a beast every trip. Especially the long battery life even on 3rd gear the whole 6-7 miles I go Overall I give it a 9 out of 10

Seems to be good

Haven't had anyone try to break this lock (yet), maybe it has to do with how beastly this thing looks. It's *heavy* so careful with that if you're trying to save weight. The lock mechanism feels good, the chain is very strong... no complaints here. AA battery in picture for scale.

Excellent lock.

Most definitely, I recommend this Bicycle lock. When I read the word "Kryptonite" the first thing that came to my mind was "Superman" lol. don't let the name fool you. It stands to its name. It is strong, durable and I think it sends an automatic warning to its viewers.
