I came across a blog about the design and construction of electric powered tadpole trikes. It is named tadpoletrikeman. The owner of the blog has built a homemade electric assist powered tadpole trike he calls Speed Trike. Here is a photo of it.
Although he made the frame he has used a TerraTrike seat and front wheels on it so if you don’t look carefully one may think at first glance it is a TerraTrike.
At this point in time he only has this one trike featured. Hopefully other material will be offered on the blog in the future.
As you can see in these pictures he has done a very nice job building the trike. It looks great.
As you can see he used a bolt for the front axles. That is the same thing I did when I built my tadpole trike. It is quite common and works quite well. Just be sure it is strong enough (hardened grade 5 or 8 and 5/8 inch diameter if my memory serves me right).
Underseat indirect steering was employed.
The rear view mirror is mounted on the steering head.
I encourage you to check out this blog. And by all means …
KEEP ON TRIKIN’
