My son loved this sucker - toted him everywhere, but now that he is 3 he has his own 2 wheels - we loved this because you could leave the metal pin on the bike and remove the seat easily when you didn't need it - meant you could ride your bike without aways having a kids seat attached. Don't get me wrong, I never attempted to put this thing on either my tri bike or road bike, but it was great on my commuter/cruiser bike. Husband says $40 + shipping...
