Outfits are an aquired taste,look to full size for a solution with ideas,Grinnall do an interesting 3 wheeler

and various people have tried 2 at the front,seems to work best with the rear central anything else with 3 wheels seems to have stability problems and/or tourque steer problems.
Off set 3 wheelers such as bike outfits pull to one side whilst accelerating and pull to the other side whilst braking.
2 or 4 wheels are better than 3 in general IMHO but try to keep going you might find something new.
Good luck.
