U-lock vs Chain lock: Which is best? | The Best Bike Lock says,
If you're looking for a portable lock to secure your bike in the street every day, then you're probably best off with a U-lock. Whereas if you're only looking for a lock to protect your bike at home or at work, then the best choice is a thick, high quality chain lock.
At 5 Things Bike Lock Companies Don't Want You to Know Daniel Idzkowski recommends SkunkLock which releases noxious chemicals when thieves try to cut through your lock.
