Thick steel U-lock that feels heavy duty.

This U-lock fits snugly around my 4” fat tire wheel on my e-bike. It's made from pretty thick alloy metal that is heavy. This lock has a high end feel to it. I'd imagine it would take some time to cut through this lock, and would slow down a would be thief. Used in conjunction with a chain lock and audible alarm hopefully will be enough deterrent.

Solid U Lock

Thick, solid u lock. Rubber coated. Key entry at bottom center bar with regular key, instead of annoying round key at end. I think this one is secure %26 will work well
