This folding lock by Kryptonite comes with 8 mm thick, movable links made from hardened steel. This allows you to flexibly use the lock and to secure your bike almost anywhere you like. It provides high resistance to attacks through cutting and pulling. Its thick coating protects the bike's paint. When riding, you can store it safely in the included holder that can either be fixed at the bottle cage drilling with two bolts or to the frame of your bike with two rubberised velcro straps.
Children's bikes are generally measured by wheel size, rather than by frame size. Remember children do grow very quickly and you need to take this into consideration when buying a kids bike, However, if you buy a bike that is simply too big for your child, you will compromise your child's safety, and ultimately discourage your child from cycling.

Which Size Bike Do I Require?
