For peace of mind while running errands we're using the Abus Bordo Granit XPlus 6500 Folding Lock to keep our bikes secure and theft-free. This bike lock stays neatly folded up and out of the way while not in use but folds out to accommodate our bikes while we're at the brewery or getting groceries. The smartly mounted bracket fits securely on our unused water bottle bosses, helping store the lock as easily as ever.
