Hey guys- did a mash up today of two of my non riders to make something ill actually use. 90s mountain bike and a crappy sears tricycle i cut the seat post off the trike and down tube and reverse it into the down tube of the mountain bike. Then i can just reweld the seat post and the pedals stay intact. I have my honda gc160 build with a 22 mikuni carb going on and ill have to think about a tank later on. Next thing is the flat bed part i want to weld up bracketing to do a classic pickup truck stakebed with lots of reinforcement on the seat post... and hide the engine so it doesn't look like its 160cc 
check the pictures and comment on any problems you might see with it its my first trike build!
