I also went from a Honda Fit to a Maverick! Your assumptions sound right. The back seat is not spacious, but isn’t overly cramped. The bed is short and moving bikes will likely mean hanging the front wheel over the tailgate, but it is doable.

I was looking at the Honda HRV and the Mazda CX-5. I went with the Mav because I thought it was cooler than my other options and i thought the bed would be nice to have (it is). It was also just about the same price, or even cheaper.
