OMW, congrats. Excellent work, really matches bike's style
Few technical questions:
-how does three-point mounting do? You have tested it "few" miles :)
-do you plan to use this big disc brake or it's only a decoration?
-is the trunk fully sealed or only top cover?

Thanks for your interest. The three point mount works very well although I have a small link from the bottom mount going forward to the sidecar chassis now as well. This gives a bit of triangulation. I have probably done a 1000 miles or so since it was put on the road. The disc was attached to the Jawa wheel I had in my garage and I left on. The stopping power is pretty good and it brakes straight so I don't think I will connect up. The trunk has car door seals around the top which keeps the inside quite dry.

Your construction helped me invaluably to make my own sidecar, because my bike doesn't have places for four point mounts and motor is a part of bottom frame - who has designed such crap?
I think the double struts are essential for such sidecar and this is the thing that was missing in my searchings.
Now i got some frame and other parts, and a lightweight wheel with drum brake.

How did you set the geometry? I'd do it using these two shorter struts, then after setting up everything (toe-in, lean-out, wheel lead), simply adjust the longer struts to match the shorter ones. But I dont know if i think properly.

I am sorry for the delay in replying. I set the lean out quite easily. The main clamp around the sidecar chassis holds the bike once the allen bolts are tightened. The struts then just have to be adjusted to length to bolt on. The toe in is set simply by adjusting what were the chain adjuster on the sidecar swingarm. I did not need to adjust anything afterwards as it rides well and straight as is. I have had to change the sidecar spring rate and have added MZ sidecar rating front springs. Please let me know if you need more info.

Hi OMW

Joined up here to say this is awesome really loving your work and Next time your about if you could answer me a couple of questions please.

I have a ETZ 125 12 or so hp I have had it ported

Do you think with a ratio change It could pull a hack like this? I dont mind loosing top end speed for more bottom grunt

Could i make this to your design but shed a little wieght using thinner walled box or is the wieght what keeps this rig stable cause it does look heavy

Your bottom hack to bikeframe mounts are you using the same mounting points from the other side two? http://i53.photobucket.com/albums/g7...4/DSC01676.jpg

Cheers Dave

Hi Dave Welcome to the forum. I think the 125 will be a bit underpowered with a sidecar attached. The 250 struggles a bit in headwinds and very steep hills. I can cruise 50 mph and it will get up to 65/70mph. The gearing has been dropped which helps. The sidecar is quite light as it is just tubes and alloy chequer plate. I would not go any smaller on the tubes as they will flex more easily. The bottom mount is the same both sides. I would recommend starting with a 250 or 300 if you can.

I knew there was something not quite right ! Here in the UK you can only have a right hand chair if registered before 1981, but you can have a car with the steering wheel on the wrong side. Politicians !!
