Locking up a trike is usually more involved than locking up a traditional bike. And sometimes there is nothing to lock it to. I'm almost always in earshot of my trike so I added a vibration sensor alarm to my trike.
I'm not endorsing any particular product. I like the peace of mind a vibration sensor alarm gives me. When going into a store, taking a short walk on a trail and going to a restroom I set the alarm.
