My boyfriend bought me the bike this past weekend, I don't own a lock yet so we shared one. He took his with him on his bike to work today. I was home all day and it was in my clear site. I left the kitchen (that is off the back patio where there's a wooden enclosed private fence stretching 10 feet high) for a short time. when I came back it was gone. We are on the 1st floor. There is a locked entry/exit on both front and back of apartment. When I came out to investigate, the back door that auto locks from the inside when closed was wide open and a cement block was on the ground propping it from closing. Knocked on the neighbors doors, out of the 5 units on either side only 2 were home and they reported no knowledge or any suspicious activity or ever in the 2 years they've lived here. Couldn't see any signs of breaking and entering either. Someone came up to our porch and stole it making a hasty escape through the backdoor leaving it open.
