|Power assist trailer version 2
This trailer used a 2.5 hp engine I bought from Harbor Freight turning a 24v alternator. It did work but could not put out enough amperage to effectively run the trike without stalling the motor all the time.

Dump Truck Trailer
It was built on the frame of the big power assist trailer since I rarely used it. It's not fancy but it gets the job done and I can pull it around with my mobility scooter in the yard.
Power pusher 49cc gas assist trailer Version 2
I had a bit of trouble getting the throttle cable working properly at first as I wanted to be able to disconnect the trailer from my trike. I came up with a simply was to connect and disconnect the cables but it turned out the return spring on the carburetor wasn't quite strong enough to pull all the extra cable and return to idle when I released the throttle on the trike.
Only thing worth saving... engine and rear wheel Building the trailer frame

Trike with trailer mounted on the back. The trike normally has a back deck and basket mounted on it. I had it off for electrical wiring when I took this picture.
Power pusher electric assist trailer Version 1
This trailer was built for a friend of mine that kept commenting that he would like to have power assist on his bike. There was a slight problem though is he has a full suspension mountain type bike so the only motor setup I could think of that would be really available to him was to get a rear wheel with a built in motor.
Unfortunately he can't afford the prices that are asked for those so I decided I would try a different direction. I had a few motors around the shop and an old rear section of a scooter. I built the scooter section into a one wheel trailer that has a 36v 750w motor on it. The basket was pieced together from a few bits of wire shelving.
The tow bar that connects to the front of the trailer was made from the rear triangle of an old 26" bike.
