### ⭐⭐⭐⭐ VERY Good but could better
*by S***N on August 6, 2025*

Top quality Bike lock that will fit 26x4 Fat Tire Electric bikes but it arrived in a package that wasn't in the best condition and it was missing the 3mm Hex key to mount the lock holder to the frame which means I had to go to Autozone and pay $12.99 for a set of hex keys just to be able to attach it to frame
