My wife got a Rad Runner because it's a good fit.  We were trying out some dirt trails and she found the bike was getting high-centered on rocks and roots. 

After looking it over, I concluded she could add 4" additional clearance by removing the existing kick stand.  However, a replacement center mount kickstand behind the bottom bracket has to have sufficient "spread" to go around the tire.  One that mounts on the wheel nut might add too much stress on the shaft and a mount on the chain stay has to be threaded through cables and an irregular tube shape.

Has anyone found a replacement?
