URBAN UR6 Hi-Tech Motorcycle Disc Lock with Smart Alarm | Best Value | 120dB, LED, Warning, A+ Sensitivity, Truly Waterproof, Long-Life CR2 Battery, Carried Locked, Bike Anti Theft Wheel Brake Locks

Why we love it
  • Versatile alarm and sensitivity.
  • Long-lasting, replaceable battery.
  • Fully waterproof and reliable.
Main Highlights
  • SMART SECURITY THAT MAKES THE DIFFERENCE: Not all alarm disc locks are the same. The URBAN UR6 goes beyond basic alarms. You will love its smart, high-value features like the WARNING pre-alert, A+ sensitivity and light signal. Use it with or without alarm, you choose. It detects theft attempts to scare thieves away before the 120 dB alarm sounds (watch video). The 6 mm pin fits most motorcycle and bike brake discs (for larger holes, we recommend a 10 mm double-locking Urban UR10 or above)
  • REPLACEABLE HI-TECH ELECTRONIC MODULE & LONG-LASTING BATTERY: This great motorcycle lock features the patented UR24MA replaceable alarm module, a hi-tech, fully sealed and compact electronic unit with no loose cables, built for long-term reliability. Unlike basic alarm locks, the module can be replaced without wasting the whole lock. It uses a long-lasting CR2 lithium battery, resistant to cold weather and already installed. Under normal use, it lasts 2–3 years and is quick and easy to replace.
  • TRULY WATERPROOF: Rain won’t stop your protection. The URBAN UR6 is waterproof inside and out, thanks to its truly hermetic alarm module and anti-rusting treatment. Best value alarm brake disc lock, designed for daily urban use, it keeps working reliably in rain, humidity and outdoor parking, so you can leave your motorcycle with confidence—whatever the weather.
  • MORE PRACTICAL & SAFELY CARRIED LOCKED: Designed to make your daily rides easier. Thanks to the electronic WARNING reminder function, you don’t need a reminder cable: if your motorcycle is touched, 6 warning beeps alert you. The URBAN UR6 locks quickly with one hand and no key. This practic disc lock can also be safely carried locked on your bike using the optional UR351 or UR352 mounts (not included), so it’s always ready when you park.
  • RECOGNIZED PRESTIGIOUS BRAND: Keep the thief away. URBAN is a well-known European manufacturer of high security locks for motorcycles, scooters and bicycles. If you need help, they are always available to assist you. URBAN SECURITY "Enjoy Moving. Feel Safe."
