i live in a gated condo comunity and they jumped the fence and stole the motorized bicycle right off my porch. i felt secure and didnt lock it so my fault. it takes just a few minutes to lock them up and at least that way you may hear someone messing with it. my new ride i am going to keep in a locked storage area in the condo complex pluss a pad lock on it and also this alarm from jc whitney Link.....
