Superbly solid build!👍 Definitely a longevity item and Diamond level too👍
Checked out a few in this category and went with this guy from this highly rated company due to their many cleverly-engineered multiple line of security and Diamond rating products - (which was a priority for me), in addition to weight (also another priority), keyed lock not combo with key registration for lifetime replacement if needed.Then it the was color scheme (black 👍), looks (eye candy😏), availability, available holder for frame mounting and my absolute favorite - can be used as a weapon in case of suddenly while on the streets, someone or someones 😮decides to get stupid with me while I'm riding🧐🤔🙄 Kapow👊 Bing Bam✌️👍. Who's the victim now😂😂😂

Highly Rated Security For Expensive E-bike
Bought this to secure an expensive e-Hunting Bike. It's big. It's bulky. But it's tremendously secure. I use it in conjunction with a chain lock so I have variety of ways to secure my bike.

Good product
Quality lock for affordable price when comparing to Abus or any of the higher end locks. Only gripe is it’s too small really for my frame and I’ll have to buy an additional chain.Key action is amazing and the mount is sold separately***

No holder?!
Lock seems hefty n secure, but NO HOLDER?? NO OPTIONS TO EVEN BUY A CORRESPONDING HOLDER?? This is not acceptable.

Sold secure diamond rated gem
Although I have not experienced a theft attempt while using this U-lock, it is sold secure diamond rated according to the sold secure website and the large size allows me to lock my gotrax campus scooter to a variety of bike racks. It's durable and the build quality is sturdy it does not weigh much and its functionalitt is easy to use.
