any good alarms out there?I used to own a franchised detailing /car accessory business, and installed thousands of car alarms. Whats out there for bicycles? Locks? remotes? That 141 dollar one looks neat, but ya gotta buy a sim card? What are yall using? I hate to carry a cable lock on my older bikes. I do carry one on my Trek. Dont wanna scratch paint on the non-stock painted bikes.
