I would think the bike. The side car will be for shorter most likely (based on where handles are).
Not gonna lie, it's a bit of a PITA w/ long legs to ride wavebreaker, but it's ok. If you've ridden FoP, its similar to that w/o a back or shin guard. And the handles are further ahead than FoP.
So picture 2 FoP seats side by side w/ no room in between them except a small elevated climb-thru, and that's wavebreaker.
