Found these on the Reverse trike owners and builders website. I just thought the idea is a good way to get started in building your own RT. I do have to say it's also just for the learning curve to the real trials and errors in building. Then you decide if you want to build a better one, or stop there and just admire what you can do. There are no losers doing this.
This guy wanted the smallest & lightest RT he could build. It's a good start for a off road around the homestead play toy. I kinda liked it even with the limited power and suspension. Might be a lot of fun.
And there's always the half quad front with a scooter rear drivetrain RT.
If you want larger pictures ask me for them and i will email them to you. They are around 2000 pixels by 1500 pixel pictures.
