Planet Bike's Seat Leash tethers your saddle to your bike frame, adding an extra hurdle for potential thieves. It's 24 inches long and 2.5mm in diameter. The entire cable is also plastic coated to protect your bike's finish.

Planet Bike's Wheel Tether is the perfect complement for your U-lock (sold separately). It secures your front wheel and weighs half as much as ordinary accessory cables. The 31-inch-long, 5mm-diameter Wheel Tether is a great way to safeguard your seat and accessories, too. And, it can be used alone with a padlock for security in low-crime areas.
