White Lightning's Bike Johnny Bicycle Cover lets you store and transport your bike without making a mess. Have you ever put a muddy mountain bike into your car or left a bike sitting in the garage for the winter? You end up with a dirty truck or a bike damaged by the elements. With the Bike Johnny, you can save your car's interior and protect your bike from the elements! It's made from a water repelling and UV resistant nylon. This durable material protects your bike from the elements and your house, apartment, dorm, or car from your bike. Plus, thanks to the grommets on the side, you can easily lock your bike for extended storage while keeping the bike covered. The Bike Johnny also features bidirectional zippers that make installation a breeze. The Bike Johnny comes in one size that fits road bikes, triathlon bikes, mountain bikes (including 29ers), BMX bikes, hybrid bikes, and comfort bikes. It also includes a pouch for easy storage when not in use.
