I have been building 3 wheel trike for about 9 years this is version 3.
The original started out as 2 person, it was way to long. Could not U turn in the street, you had to get off pick up rear walk it around.
So I cut 18 inches out of the frame. Which had big affect on the Ackerman steering. Original had no suspension, it was very hard ride. Made it squirrelly to ride felt like it was going to flip with any speed.
Ver.3 will U turn in 1 lane, at speed and solid feel.
I messed around with putting on some body / faring design. I did not like the looks or feel.
