Hi Richard: Our friend Motra sent me a bunch of photo's all about the charger's and the load star three wheelers. His goal is to have a trike too and the step through design would make it very rider friendly for people with limited lets say flexibility. LOL I found the tires like yours new from Dennis Carpenter Cushman for $75.00 each but they want too much for the wheels but I do like that flat top tread pattern and the taller overall diameter just have to git my mind around the price. LOL That means to sell another Heat Pump or AC system for more play money. So on goes the ( CushGote ) Trike progress.
What engine is in your trike ? I have a cast Iron 8 HP Tecumseh with electric start and dual coil alternator but the little sucker is 70 pounds light. I will put some pictures in a new photo album for the frame I got for this project.
