BIKE AND DOG is a special leash allows you to ride your bicycle while walking your dog with complete security MAXIMUM PERFORMANCE The need of dogs to get faster made us design a system to attach them to bicycles in the safest and most comfortable way for us and for them. We recommend that you use the leash to take your dog to a location where you can eventually unhook them, let them run and freely keep up while you ride your bicycle as well. MAXIMUM SAFETY Attaches on the axis of the rear wheel ensuring the smallest load on the bike and where the dog exerts the least amount of lever arm force. MAXIMUM SIMPLICITY You can hook it with out any tools right next to the axis of the rear wheel in seconds.it is compatible for bicycle wheels with different types of axis. Depending on which is being used. MAXIMUM COMFORT Once you arrive with your dog at a secure location and unfasten him from the leash, it will recoil so you can hook the end anywhere on the bike and won't even notice it is there! THE SAFEST LENGTH We found the safest length for the leash that will impede the dog from moving too far from the bicycle. You will always know which side your dog is on so obstacles on route can be overcome with ease. MAXIMUM ADAPTABILITY Since there are no rigid parts to this system and the leash recoils back to its initial length when not being pulled by the dog, it is optimal for narrow areas such as parked cars, busy sidewalks allowing the dog to get as close to the bicycle as possible. This makes it comfortable and convenient when riding through areas of heavy transit. UNBREAKABLE CARRYING 3 DOGS IN BIKE WITH TOTAL SECURITY You can connect up to 3 dogs. SCOOTER AND DOG Perfect for using with a scooter and wheelchair. The dogs are happy running, they are designed to run. If you just walk them, they will not do enough exercise to be healthy.
