What i did this morning before heading for the trail was to reinvent the small light weight trailer I build for the small bike I had earlier. It is made from 12 inch bike tires and light weight plywood and light weight steel L shaped braces. I cut down the number of batteries i use and off I went. It worked much better. I was quite happy with the way it worked actually. I'm not sure just what I will do with the nimh batteries but I will work out something I'm sure.
