The lock (not provided) is threaded down a waterproof tube which runs through the shield/visor aperture and out of the bottom of the helmet so that you can lock it to the bike. The easiest lock to use is an armored cable lock (such as an Oxford Barrier Cable Lock), but you could equally use a chain lock or a regular cable lock. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
