Recent medical issues hinder my ability to walk on uneven terrain (dirt roads, etc.). Previously, I have depended on walking out as last resort if trouble occurs in my offroad wandering (never had to do). 'course, that avenue is now NG, so looking for a new "life boat" concept....electric MB (mini-bikes = too heavy). After using search in this forum, I don't see any recent (post '10) threads. Anyone have any advise as to which electric MB would serve this purpose (no serious extended technical riding, just bailing in typical expo type terrain, say max 50 miles....can you say white rim trail).
