I have an older 20 inch hub motor that used to be on a folding supercycle from the 70s. I added a suspension seat post after the pounding of no suspension gave me back spasms, that required 2 week of physio.
I also have a Golden Motor 13 inch scooter wheel, but no controller. This I plan to mount on a bike trailer, home made like a bob. It will also have suspended trainer type wheels as with the batt pak it will be a heavy beast.
The frame is started, and I have all the parts. No welder yet, so I plan on using the metal plate and rivets/screws for attachment of cargo pod and removable cooler pod mounts.
I was surfing Utah Trikes and they sell an elec pusher trailer that looks alright
That is it for now, cheers from Niagara Falls, Adventureboy7
