Well here she is people. The trike was $279+ freight. Motor 350w , MY1016Z, $169, controller $12, plus sundries(throttle, etc.) Free-wheeling crank $43. 12 tooth freewheel cog $7. I had a keyed and threaded bush made up for the frewheeling cog on the motor as well ($100!)The batteries are 4x 15ah 12v, 24 volt system, This battery box came out a 48v electric pedal scooter. The trailer is a Repco tag-a-long. The panel 80w, foldable, is wired in series to a 24 volt controller. 25 kph safe max. with pedalling, without trailer. Old Turbo-dog rides in the trailer. Theoretically in full sun you could go 1/4 throttle all day without pedalling at all. With little effort you barely run the battery down at all.
