Been out for a 20 mile cycle- was easy to stop and let him out when we stopped - then pop him back in. He loved but . There were times he wanted to get out - as much as he climbed on my back he was completely secure. Should have bought the one with the sack on the back for carrying our coats etc. Next day we walked and took the sack incase he became tired ( no such luck). Bag was light and versatile enough to use for our coats. Great product - got lots of comments and laughs as many had not seen a dog on someone’s shoulders on a bike. Look forward to many more adventures.
