Adult kickbike. Rare in the states. Made in Finland and used to train sled dogs. If you have a big high energy dog, this just might be the thing you need. I trained my dog with this and it is a good workout for both dog and human. But you don't need a dog to get great exercise. If you're interested, I'll throw in the Training Lead Dogs book. Has a bit of wear and tear, but in overall great condition. It's a lot of fun and good for the beach too. When it gets crowded, It's easy to stop and just walk with it.
