LumaGuard Rechargeable Bike Alarm, 120dB, Four Alert Modes

Lock up with a little extra backup: the LumaGuard clips onto your bike and stands ready to sound off at 120 decibels the moment something's wrong, loud enough to cut through city traffic or carry across a quiet trail. It's small enough to sit alongside your other gear without adding bulk, and it charges over USB so there's no fumbling with disposable batteries before your next ride.

Features

• 120 dB alarm — a loud, attention-grabbing sound built to deter theft and put pedestrians, drivers, and fellow riders on notice.
• USB rechargeable — top it up with a standard USB cable, so it's always ready to go before you head out.
• Four alert modes — switch between settings for different riding scenarios, including a dedicated anti-theft alarm for extra security when you lock up.

Fits right on your bike

The alarm is compact and mounts onto your existing setup without adding bulk, so it tucks in whether you're commuting through downtown traffic or heading out on a remote trail ride.
