I am fortunate to have a gym membership for the summer months. And yesterday I decided it would be a wise choice to exercise indoors due to the excessive heat and humidity we are experiencing. I rode my bike to the gym, and locked it on the empty bike rack there. In an earlier post I mentioned my aversion to numbers, so I was glad to find this lock (Wordlock) last year at Target. There are four rows of letters, and a possible 10,000 combinations for you to select from. Do you generally lock you bike up, or worry about it being taken?
