How heavy is too heavy for Rad Rover? I've watched the Barnacules Nerdgasm video where he rides the Rover being 50lbs over its max.  He seems to think it is solid but I wanted to hear from others. My dad (65yo) is about the same size (330lbs).  He really wants an eBike to ride on residential streets and some gravel/dirt trails near his house.  I was thinking the RadWagon could be an option weight wise but the Rover is much more what he would want, especially for the gravel/dirt trails.  

Any other heavy riders out there on the Rover?  Thoughts?

Any thoughts on if the normal rover would support him better than the step through?
