fat tire electric bicycle
Yes, we convert fat tire bicycles to mountain climbing machines. The motor must go on the front and the rims must have 36 spokes.

John Powell, who owns JP Aerospace, came to us with a mission.  The mission was to convert his fat tire bike to a mountain climbing machine that he could use to retrieve items returning from his space program.  These items sometimes end up in remote locations.  Please see his site to appreciate what he is doing: http://www.jpaerospace.com/index.html

Mission Accomplished!  This was done with the best of the best high-end 48V geared hub motor, which now provides over 1300 watts of peak power.
