U-locks are big, ugly and awkward to mount on a bike. The lock companies have tried for years to find a sufficiently strong, reliable alternative to them.
Heavy duty chain locks are tough enough but don't mount on a bike. They are almost always carried in a basket, pannier bag or backpack.
A few years ago the Abus brand invented the folding bike lock with its Bordo model. This new Kryptonite version of that is sightly larger, more affordable, stores easily on the bike and looks great.
Made of 3mm thick hardened steel plates and coated with thick rubber, the Keeper 585 unfolds like origami to a larger than U-lock size and is tougher than most of the U-locks on the market.
Add a double ended cable to secure your wheels to the lock for greater security.
Free installation on to your bike when purchased in-store.
