This trike started out as a push trolley from a hardware store which carried batteries behind a bike, the original trolley part of the frame makes up the battery box section, it kept and keeps evolving over the years, finally gave it a decent paint job and trying some nimh batteries. Have been using for maybe 6 months with 4 lots of 20ahr sla agm batteries, I in fact prefer them to the nimh strangely enough.
