Learning to lock up your bike properly is essential to keeping it in your hands. The proper lock used well will help assure your bike stays where you put it.

A modern blue bike locked to a rack using a u-lock on the frame and the rack and a cable around both the front and rear wheels connected to the u-lock.


Most importantly, use a u-lock or a high-quality chain lock for the frame. Lock the front wheel with a cable, chain, or u-lock. If you’re leaving your bike for a while, lock the rear wheel too.

Locking a wheel with your u-lock is great when possible. Depending on the bike and the rack, this isn't always possible.

Be sure to lock your bike frame to the rack – not only a wheel. Avoid using bike racks where you can't lock the frame to the rack.
