Sadly this otherwise perfect seat is impossible to install if you also have yhe clubhouse mini. We’ve had my kiddo on the HSD in a Yepp Seat with the clubhouse mini and storm shield system, which now that he’s 5 I just removed. Thought it would be fun for him to enjoy the fresh air with me this summer. But the attachment mechanism on the sidekick seat is too wide to fit between the welded sides of the clubhouse mini that attach to the rack. I’m so bummed! I’ve been trying to modify it all afternoon to make it work but I’m going to have to go with aftermarket seat :(

Comfortable and easy to install
