Super Creative Idea

If I use the word "Trike" or "Tricycle" as a subject, most people will skip the post.

Thinking about building a Tadpole and was wondering if anyone has any suggestions?

Would start with a 26" steel bike frame, seven speed. Build the two wheel front from scrap bikes. Thought about "wagon style" for steering, but the wheels would bump into the frame and not allow sharp turns. Twenty inch steerable is my current thought.

That's a great idea. Are you planning to build with an electric drive?..

Yes indeed, RWD.
Big worry is that "tadpoles" don't turn sharp like the "delta" for use around town.
