Yes, mini-max, but the baby isn't born yet! I'm planning to strap a car seat first, then I'll take it from there. Currently the Yepp plate is only for the cargo, but I have seen it adapted for mini-max.
Yeah this is odd, I'm assuming it's because of the top of the headset protrudes so far from the forks. It looks very over engineered, I'm wounding about getting one and either modifying it, or using it as a template to make my own.
@Lolo do you have a pic of yours with a child-carrying setup? I take it you have mini-max?
