It’s not safe to ride a bike while using a traditional hands-free dog leash. When biking with your dog, it’s vital that your dog not veer too close to the bike or he could become injured and/or cause you to lose control of the bike. Additionally, if your dog lunged hard, it could pull you right off your bike. Special bike leashes for dogs are similar to hands-free dog leashes, but rather than attaching to the human, bike leashes attach to the bike via a rigid arm that positions your dog a safe distance from the bike.
