So today I am trying to plan out this build. Trying to decide how i want to start and what section to start on.
I have searched the web for swing bikes, and there is pretty much 2 ways I see them made. The Original production swing bike, the rear swing joint is the seat post/head set, basically the rear portion is built around a front fork. In this design the rider is on top of or behind the rear axle. In my experience riding a bike behind the rear axle, usually means you're doing wheelies, and I don't think that would be easy on a swing bike. The other way i have seen them made is basically a fork steer tube welded in front of the seat tube, and allows a "normal" geometry, and I would think more stable.Then again, I'm going to throw burrito bike into the mix, which maybe isn't the easiest bike type to ride? I was also thinking about taking measurements off of my other bikes, which all share the same reach, and saddle to peddle lengths, so maybe need to take that into consideration? Maybe I should try to match the head tube angle of the Huffy, as cruiser geometry is very stable. I do love aggressive rakes, but having it swing around might not be rideable.
So I think i will go with a modified version of the latter of the two swing/pivot designs. The design I have in mind would look like a control arm of a wishbone suspension system turned on its side/vertical, with 3 headsets stacked on each other, with the center one attached to the rear frame section. The fork steer tube would be removable, like a pin holding it all together. I think making the swing portion is probably the best place to start. I do wish I had a motorcycle jig to do this but I think I can improvise one with 2x4s. Also I am going to use my little hobby grade weld machine, and run flux core. I'll need to go grab a spool of .023 wire. Also i do not have a chop saw, or even better a band saw, just an angle grinder and cut off wheels, so cutting and fitting 3 headsets I think will be the hardest part of this build.
Maybe I can get out in the garage after work to start cutting some stuff up!
