Besides handlebar locks, install additional locks on the bike's front and rear wheels.

Install immobilisers, which prevent engines from being started without special keys.

At night, park in a well-lit spot, and in view of a security camera if possible.

Attach and lock your bike to something immovable and solid, such as a strong pole. This makes it harder for thieves to steal your bike.

If you're with a biker buddy, use a chain lock to secure both bikes together.

Never leave the keys in your bike's ignition, even if you are only going to be away for a few seconds.
