I am sorry for your loss. I had my beloved bike friday pocket rocket pro stolen locked securely to a bike rack near a security guard booth at work. I used a combo cable lock, and I learned after the fact how easy it is to break BOTH combo and cable locks. I purchased a NYC kryptonite lock for nearly $100 that weighs 5 lbs, and keep it permanently on the bike rack, but no more bike thefts! I have a second one that I use if I go downtown and want to leave it. You could consider a used touring bike, you can put a rack on with shopping panniers for errands, and also have it for road riding and even touring which can be a lot of fun.
