@BD27 You probably have the newer fork, Vik bought his quite a bit later than mine. @zoomit I was running the stem backward but I turned it back around this summer so I could have some more room. On longer trips, my daughter generally sits on the floor rather than the seat and on really long trips, there is always a duffel bag or something to sit on and she doesn't get bonked. Also, my spider-like physique likes to be stretched out a little more than most.
Enjoy your camping trip. Your new bike is very well suited to camping with a 4 year old.
