Mini crown can take 1.5 people (bench style seat), ie: One adult and one smallish child. So you don't slide in the seat when driving solo a wedge is a good idea. The aerocrown is much lighter, and is a single seat. My seat has a high back and nice padded arm rests and is very very comfortable. The suspension is a dream the wheels don't sink in and the design is awesome. You can add extras like a nice dash cover and you can take out the floor and use stirrups if you want for marathon. I have the basic design with the nice higher back seat that hugs you in. You might want to investigate weight of driver recommendations, of the aerocrown vs the bellcrown. Delicately putting it, for larger bottomed drivers might want to consider one design over the other, that said.. when I was a bit larger I still fit in the aerocrown nicely, so to spell it out, big bottoms fit, but really big bottoms might not. (sorry, just trying to help describe what I know).......
I got mine with burgandy wheels and it is gorgeous and easy to keep clean. my boy pulled it like nothing was behind him. You can order them with custom height seat for shorter or longer legged folks. The aerocrown fit me nicely factory with my feet on the floor and just the right height, but in the aerocrown my legs dangled and I would have ordered a lower seat if I had chosen a bellcrown over the aerocrown. For me trying one vs the other, the aerocrown won hands down on comfort.
You simply don't move at all in the seat and you can enter and exit in about one second. It is that easy. On hills my boy struggled on with my wooden cart, he breezed up in the aerocrown. Even grossly out of shape he pulls the aerocrown nicely. The aerocrown back is a bit higher than the bellcrown and I found that more comfortable and supporting.
One cart for all in my opinion. Many other folks on here would agree. I wanted a hyperbike badly but I am not limber and my boy does not have a steady stand or whoa all the time so the aerocrown was my 2 choice. It is really pretty and has a nice seat pad that you can remove.

I got the top photo seat and the burgandy wheels, wheel color is not extra. I got mine from Carriage machine shop in Pa from Steven Stoltzfus, same price as everywhere else, seems consistant on price everywhere. You can get marathon shafts, I got regular. It fit in my suv with shafts off for taking home. Love it. wish I had more time to drive. best wishes.
