U-locks offer security, at a good price, without sacrificing too much practicality. And if you try to bump up the security with a thicker chain, you rapidly loose practicality because they’re so heavy. U-locks are relatively light and their stiff shape means they are easy to fasten around your bike.
Do you know what level of security you need? Where you lock your bike and for how long are two important considerations when choosing your security level. Generally, bikes locked for longer periods of time or bikes locked on college campuses or in urban areas should use higher security.
