EnzZone Alarm U Lock for E-Bikes - 16mm (⅝) Hardened Steel, Motion-Activated Alarm, Fits Fat Tire E-Bikes, 3 Keys, Weatherproof, (Red)

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., Weight: 0.1 Pounds, Manufacturer: ENZZONE
