Your dog will learn to use the Bike Tow Leash quickly and will enjoy the freedom to run at his own pace. If your dog wants to go faster than you can pedal, you can allow him to propel your bike. Instead of holding your dog back, let him take you for a ride! * Proven safe. The Bike Tow Leash"s unique patented mast prevents the bike from tipping when the dog pulls, reduces any jolts and gently trains your dog to stay in heel position. The resilient mast will allow your dog to catch up when you turn away, notifies dogs of turns toward them and allows dogs to drop behind the bike to avoid obstacles. * Great for fun, exercise and exploration. The Bike Tow Leash will allow you to exercise your dog in less time while covering the same or even more distance! Imagine going more places with your dog as exercise partner and companion: trail rides, camping, the park and store . Remember the dog trainer mantra: "A tired dog is a good dog!" * The Bike Tow Leash installs and removes in about a minute without tools. Move it from bicycle to bicycle or simply clip it to the back of your seat out of the way when riding without your dog. * Made in the USA and patent pending.
