Great for my e-bike
Love the lock. Just make sure you follow the directions when you are setting your combination. I was off with one number it took a bit to figure it out

Does the job, great 5 digital combo.
This bike lock is heavy duty! Easily to reprogram to my own 5 digital code (took about 30 seconds). I like that the combo is 5 numbers, allowing me to use a memorable zip code (not 90210). The chain has a nice weight to it giving me piece of mind.

Matches my Mongoose Excursion
I was torn between the pink one and the black one, but ultimately decided on the pink one and it looks cute with my Mongoose Excursion bike. Pardon the crappy basement lighting, I live in an apartment complex, and my bike is in my basement because I don’t want to expose it to the elements if I were to have it on my balcony. Plus, my balcony stairs are too steep for my liking compared to the interior stairs. I was able to change my bike lock code just fine. I like that the pink fabric is decently thick and not thin, which protects the beautiful design of my bike.

Great Chain
My only gripe is that it’s a little short. Otherwise, great chain.

Scooter is now secure!
I use this for my scooters and it is a hardened chain that is wrapped, so it doesn't scratch my paint. Hardened chain should last longer than the scooter will, so it will be used on the next one too. The 5 number lock is a bit more secure than a 4 number, so that is even better than most locks. Its heavy enough to be tough, but light enough to not effect the speed or capability of the scooter. Great value.
