Best For Folding Bike: Sunlite Best Lock

Buy on Amazon

The sunlite best lock is specially designed for your daily usage and has all useful features. U-locks are very susceptible to pry attacks, in which their rigidity is used against them. If you need something really burly and want an integrated lock, go for the onguard mastiff chain. You can use this to lock your front wheel and literally every bike in your city will be easier to steal than yours. The keys are laser cut, so they've got four sets of pins and are incredibly hard to pick. There are no exposed links, so if a thief wants to try a pry attack, they have to take the extra step of cutting the cover.
