Although I have never seen one, the McBean hive barrow had a bicycle wheel 
(large wheel - good for rough ground) but then kept the centre of gravity 
low - perhaps a bit like this:

    *    *                           _________
 *    ___*                      /
*            *\__________/
   *     *

Hmmm, never was that good at drawing, but perhaps you get the idea.  The 
large wheel and low centre of gravity apparently made it very stable.

Best wishes
