I picked up a rusty chrome Giant Stiletto for $30 a couple years ago and had always planned to make it a shifter but for some reason I triked it instead. I had also planned to take my time and do it right but thanks to the impending demise of my current and first bike that's not happening either. I'm to lazy to go into build details pictures will do that for me. I will tell you major mistakes were made and this thing has five chains with four different sizes lol. Current top speed with governor 20mph.
Near future plans.
A 12v lighting system with a 30-40watt solar panel as a bed cover.
Reenforce frame and rear-end.
Non stock gas tank. Homemade one buddy gave me, Harley tank or mini keg in bed.
Change gear ratio from 11.56:1 to 12.44:1 and remove governor once I know the local cops are ok with the trike.
Future plans but probably not soon.
20x4in rims with motorcycle tires on the back, 24x3in front with disk hub, and disk for each back wheel.
Clean up welds, sandblast and paint.
Probably more but I'm tired.
And yes, it has an aerosol can muffler.
