Review: Strong and Loud - Already had one of these super strong, motion alarm U-locks from a recent purchase. I bought it to help protect my e-bike. I was so impressed with it that I ordered a second one for a friend who owns an equally expensive e-bike. His opinion of the EnzZone U-lock is just as positive as mine. With a 16mm shank and loud motion alarm (which can be deactivated if not needed), the price for this lock is less than others of lower quality.
Review: Beefy lock! With loud alarm. - After doing a lot of research I settled on this lock. If I wanted to buy something better I would be spending another $260.00. When I received the lock I realized how flimsy the lock I already had was and this lock was a beast! Came nicely packaged with three keys I immediately tested out the alarm and it was pretty loud. If anybody was messing with the lock and there was anybody around they definitely would turn around to see what all the racket was about. You can tell by the feel of the lock that it's well made it's good and heavy. I purchased this lock, to lock up my new $3200.00 e-bike. I'll feel much better when I'm going in the store that the bike will still be there when I get back, just the look of the lock is enough for a bike thief to look for an easier target. Truth be told if a professional bike thief wants to get your bike they're going to get it, but you have a much better shot with this lock. I think it has more to do on where you leave the bike .You got to leave it in a place that's got plenty of people around and not in the worst block in the city. And try to lock it from the frame at the bottom to a stationary bench or pole that can't be easily removed that won't make it easy for someone with a cutter grinder to try to cut the lock.

## Features

- STOPS THEFT BEFORE IT STARTS — EnzZone's built-in motion sensor detects tampering the moment it happens, triggering an audible alarm that alerts you and sends would-be thieves running. Designed to deter, not just delay — because the best theft is the one that never happens.
- BUILT FOR FAT TIRE E-BIKES — Engineered to fit fat tire e-bikes with 20"x4" wheels, scooters, and motorcycles that standard U-locks can't accommodate. Shackle opening: 5" wide × 6" tall (7" overall width, 9" overall height, 3.2 lb) — check your setup before purchasing so you get the right fit first time.
- FRAME PROTECTION BUILT IN — The rubber-coated shackle prevents scratches and scuffs on your bike frame every time you lock up. No more marks on your paint. The coating also provides grip when securing the lock, making it faster and easier to use with gloves or in wet conditions.
- WEATHERPROOF AND BUILT FOR ALL CONDITIONS — Sealed against rain, dust and humidity so your lock performs reliably whether you're commuting in winter or leaving your bike outside overnight. The lock cylinder is protected against moisture ingress — no seizing, no jamming, no failures when you need it most.
- EVERYTHING IN THE BOX — 3 precision laser-cut keys included (one extra as a spare) so you're never locked out. Keys turn smoothly with no stiffness or fumbling — engineered for reliable use in all conditions. Available in black or red to match your ride. Registered US trademark. Backed by the EnzZone warranty and US-based customer support — if anything isn't right, we make it right.
