I finally got the trail ride thing right.I put a big sla battery pack on the trailer attached to a 12 speed rhino and off I went. I crawl along the three miles while I pedal about 50% of the time. When I pedal I leave the motor pulling just enough to compensate for the trailer and the hills. In other words I am riding a stationary bike in effect. The pull is almost ways the same. Instead of a smelly gym I get fresh air and great things to occupy my mind. Walking was boring this isn't at all.
