The basket features a cushion so your dog can comfortably lie down and has a strap for your dog's additional safety. The basket can be attached to the Basil handlebar mount. You simply click the basket in place and off you go! The handlebar mount is included in the scope of delivery. Do you want extra safety for your four-legged friend? Or can't your dog always sit still? Then you can expand this basket with the Basil Buddy Space Frame (sold separately). The Space Frame is a metal frame that you can click onto the basket to keep your dog secure in the basket.
