mini tiller powered pusher
Buck and any one else interested, this is what I have. Basically it is a 25cc Honda attached to a minitiller gearbox with a chain drive to a 6 speed freewheel on a 20 inch wheel. (Gotta love them Hondas) Last winter I basically destroyed 3 rides, and this is kind of built from the salvaged left overs. The engine drove a generator for an electric hybrid I built that didn't like having the hub motor frozen up. The wheel is from a snow thrower scrubber setup that i wiped out with on ice, and the gearbox I purchased at Home Depot when I noticed that the output is 300 RPM. Welded up some 3/4 in. sq tubing and away we went. Throttle and shifter came from a happy time setup that doesn't like being drenched 320 days a year. It gets from 160 to 220 mpg depending on cargo weight and wind. top speed on the flat is about 21 mph. I've carried up to 80 # of tools and supplies which brings top speed down to about 16 or 17 mph. Sorry the pics aren't any clearer, but we are having one of our 40 days of non rain, and my camera doesn't know what to do. So far I have almost 800 miles on it, and it has been extremely reliable. Only problem was 4 flats on the rear bike tire which was caused by a staple buried in the tire that I couldn't find until I bought a new tire and tube.
Point of interest....yesterday I was coming home, and I ran into three police officers parked in the bike lane on a bridge. Thinking they were waiting for me to lower the boom, I coasted up pedalling with the engine idling. I asked the first officer what's up? With a ppuzzled expression as he looked the rig over, he said, "Not much.....just waiting for the donut shop to open." Bout fell off the bike laughing as I pedalled away. Any further questions, let me know.
