I remember those seats looked really great for the kid and really difficult for the dad! Cowboy stop/start and nowhere for the knees to be during pedaling. We tried a front-mount one (Thule copy of the Yepp before they bought Yepp). It had similar problems and I think would be better on a Dutch with a tall short stem. Ultimately the rear-rack kind was the best for me and the first kid. The 2nd go was twins so they started and finished in a trailer. The Shotgun type showed up right around when we were done with preschool
