I am designing a sidecar for my motorcycle

I rode with a sidecar, a Velorex, for around 6 years. It came on and off very easily. It allowed me to ride in a foot of snow. I've decided to design a sidecar, but this unit will lean with the motorcycle.. Some pics on one that I am basing it on, though it will look differently. I just 3D printed the wheels and will start the frame. The working model will be a "mule', the finished product, well that's a whole 'nother basket of eggs, as when you are making something reality comes into play. The Flexit sidecar has a unique tilting mechanism that is quite ingenious. I will be duplicating that, as it uses double row 630 size chains, and I see no way of taking up slack if the chains stretch a bit, I have some ideas on that.. This side car leans with the bike, but rides and the suspension works independently from the motorcycle, meaning each units suspension does not affect the other motorcycle. Mine won't look like this, but it's general idea will be the same. Mine will have a frame and aluminum clad skin with pop rivets. I will use rods with swaged ends and large Heim joints, which will allow for adjustment. One other difference is that in a sidecar like this, the sidecar wheel axel must be in line with the motorcycle rear axle. In hard non leaning sidecars, usually the sidecar wheel is forward, as you are driving around the wheel, in this set up, you aren't, which allows the motorcycle to lean and handle just like a motorcycle should. A little bit of the best of both worlds.
that if you hit a curb, it will not

Flexit:

I had a side car body designed, but decided to go a completely different route with it. I'm posting the linkage I plan to reverse engineer.

This is a real process. When I actually physically start to make the body, I'm sure it will not look anything like that CAD model. The CAD model let's me check out the geometry, and will be necessary when I start to cut metal. I found a better armature figure.

I have decided to duplicate the leaning mechanism. I wonder if we have any mechanical engineers on the forum. I can make this, but there are some questions I could ask an engineer to facilitate the endeavor.

I've made some progress on finalizing the body of the sidecar. The design is done in a matter that I won't have to compound bend any meetal, as that's difficult, and hard in the back, even harder on the pockets!!

Me too!! :It's a work in progress. This will be a shell that goes over a steel tube frame. )

A little tweaking on the car. It will be getting a small ground effect on the front bottom to use air to hold the nose of the car in the optimum position, aerodynamics, might as well use them, they're free! There will be a headlight (modern small kind) coming out of the center top of the sidecar. I haven't put any sidelight markers, etc.. That will probably happen when I get the actual body done. I plan to make this in miniature if I can find some R/C motorcycle chain and sprockets that aren't ridiculously expensive.

I've changed my mind. I have decided using the bike's original fairing and nose piece, and some other ancillary components, I am going to twin the bike into a sidecar for. I may post images of this, it would be easier to buy the panels first, than spend 4 hrs. modeling them. So using the bike I have, I will make the frame first, using the front headlight assembly, I have a spare one, and the side panels, make an aerodynamic shell of the front, and twin the side car to the ZZR1200. I'll design an aerodynamic plug for the opening as to where the engine air would go in, sealing that opening. This will give me the front and sides. I will design a facsimile of the panels and figure our how to seat the passenger. This will make for a very light weight unit. The frame will still be as robust as it must to carry a passenger safely. The body shell will be Just that, a shell made of original panels. It should look like the bike in parallel without a front wheel and forks, etc. and the sidecar headlight may or may not be lower, it depends. I want the passenger to be able to see ahead.. The rear, will that thought process is still going on.

The original designs I did for the body bothered me I was too stuck on the Hack I had for 6 years. This will be different as much as being the same.

I'm going to try and model the fairing and side panels. It's a ridiculous amount of work, but all I have these days is time. It would be easier to build the bike without the CAD program, as far as the body goes. The CAD will definitely help in the tube lengths, and I own a tubing notcher.

Here are a couple of 3D printed wheels I did for the prototype model of the sidecar I am designing. 3D printers are finicky, always touch up work to do. These will work as they are for a mule vehicle, and I just needed wheels, front and rear, that don't need to look pretty. I could use filler, and pain them up to look pretty but there really is no reason to, as they are just to help me work out some geometry in the real world.
