The attachment looks pretty cool, but I'm not sure how I feel about the leash being so far away from reachable on the bike. If my dog lunged towards traffic while I was on the bike I'd have no way to stop it other than wiping out....or am I missing something on that springer attachment?
I bought it and it works great. I also attach a leash to Maia, 'just in case' she does lunge after a cat or something.
She is also a car/bike/rollerblade chaser, but while on the springer attachment, she does not chase or lunge after them at all. She does lunge after cats and squirrels however, hence the extra leash. That way, if she does break loose of the springer, I will still have her on leash. I am glad I bought it and the trailer for Chinook, and her when she gets tired.
Here is a link to the springer attachment:
