A FUNNY THING HAPPENED:

I saw a European male the other day that had a bicycle that he had put a weed eater motor on to make it go faster,I think he was a SCAD student. I asked him about it and he told me that it -the motor was to make the bicycle go faster without so much man power.I throught that it was a good idea and so I improved it with a 4.5 HP motor it would be perfect for the paddle wheel taxi.This is his idea and he has full credit for it. Glad to be of help. This can also be made electric to eliminate noise.
