Full Suspension Trike part 2

 
Now that the main frame is beefed it is time to add the sissy bar and its beef up. I kept the top fork portion, of the rear wheel frame, from the Magna bike because of its interesting shape. It was the perfect shape for an ornamental yet structural member of the trike.



It kinda has a retro yet modern sissy bar look so I had to keep it and did this...


 
At the point where the 2 frames connect is another example of structural weakness. Especially since part of the rear suspension will be connected to the back of the sissy bar/ seat back frame. So once again we turn to one of the parts bin bikes for help..
 

 
I cut about 4 inches from the frame tube and and did some snipping and bending to put it place.
 




With those gussets in place and welded I could then concentrate on the first part of the rear suspension.

 I had to do a little shopping at the job site today to come up with the suspension axis. I attached it to the frame work and it looks like this.

 
I also put on the first of two shocks. I then cut the seat post tube and a portion of the lower rear fork from the parts bike I got the shock from welded it to the main frame, attached this piece. and this what I have at this moment..
 
 
Next time I post there should be a top shock on the suspension and a rear axle. All this will come together into the trike that will be tested, then stripped back down to seperate parts and painted for the final product. That will be a while from now, rear wheels will be expensive.

Full Suspension Big Wheel

All 3 of you (wait I don't count). All 2 of you who have read about the dumpster dive bike that I recently finished building, will remember me discussing how I would be attempting to build a full suspension 3 wheeler. Well that project initially commenced starting its inaugural beginning today. Whew I need to quit reading that thesarus in the shitter. Any way, remember these?


 
 
 Well they are the parts bin for this hunka trash.
 
 
 
I found this beauty laying at the end of some guys drive way waiting for the trash guys to pick it up. I was on my way to the Trace for a bike ride when I  saw it and a little girls bike laying on the curb. I stopped and asked the guy if they were trash and he said yes. Well maybe to him but a treasure to me.
 
I began by stripping this Magna down to its frame. Here are several views so take notice because this thing is gonna undergo some major cosmetic surgery, ironworker style.
 




Now the top bar, seat post tube, and upper portion of the rear forks were removed. The fork head set housing was cut off, the main beam raked and the head set housing rewelded in place, giving us this..
Notice where the lower bracket (the place where the pedals used to come out of) is located?

This is now a weak point in the structure so it must be beefed up. The trick is to create some structural rigidity without adding mass. This is accomplished with a girls touch. Well just a touch of a girls bike that is....
Cute Huh?
 
See that tube leading straight into the pedal crank?  Wait for it..wait for it...
Abrafuckingcadabra that sumbitch dispearred.
It went right where the beef up was needed on the main frame which now looks like this.
 




 
That is all for today. If you are wondering where I am going with project, GOOGLE   Drift Trike and you will understand. But think of mine as an all terrain version.
