I will start adding new designs to this thread when i find them. Hers are the ones i found this week - 5-15-2019
A composite electric powered trike. Rather large but perhaps a good commuter vehicle 9.85 feet long, 7.4 foot wheelbase, 4 foot high, 37 inch cabin width. tandem seating.
This is a ultralight electric trike with a fabric body over small bent tubing. The large electric motor is positioned as far back as possible for better balance.
Next, i found this Lazareth moto Trike based on the Honda 1880 goldwing motorcycle. It is a tilting front suspension design. I would guess it is similar to the Can-am Spyder RT trike.
Then i found this very strange old design trike. NON vw front suspension, somewhat of a composite frame. maybe a BSA type parallel twin engine with a huge air cooling scoop.I would like to see the body for this one.
