    As the title says, please post pictures of your sidecar chair suspensions.

    The sidecar design tread covers some options on this but a picture says more than a thousand words. ADV has quite a lot of info on hacks/sidecars and I believe a collected tread of suspensions is still missing.

    Not so much the tug or leading link forks but the tub/chair suspensions specifically. Any construction pictures, even plans etc welcome.

    Cheers,

    Rant.

    Thanks Bobmws for the first post! Is that an air ride system to change ride height or preload beside the conventional shock? I have seen a few pics of these units on hacks but not sure whet the benefit is..

    No, that's the electric camber control that raises or lowers the hack wheel, changing the bike's angle to compensate for road crown.

    Is this an automatic thing or manual?

    Manual, uses a toggle switch on the left handle bar.

    another view different shock the arm in back attaches sway bar,uses standard 1" wheel bearings at pivot,
    Claude sells hardware and will discuss ideas if you call him.

    I have the same Works Performance shock as DB shows here. They are awesome, but I'm partial as I was friends with the founder. I've got them on all 3 corners

    I have the same set-up as davebig, on a very different bike. Like it a lot

    Cool, thanks for the replies guys, quickly finding out that Claude's experience carries a lot of weight around here and rightly so, most of his ideas and rigs seem very well thought out and put together. I wish I had the disposable cash to have him sort my rig out but unfortunately I don't. I do have access to a decent-ish machine shop and can weld pretty good so am not at all adverse to fabricating my own setup. My Watsonian chair came with a setup that was great.. in 1968, shocks and tyres have moved on since then so I figure an update is needed. I wont be building it into a HP rig or an offroad rigbut it will be low to the ground (about 4" under the engine) and I would like the chair (currently at 8" with a 10" wheel) to end up with similar ground clearance but a more conventional 14-15" car wheel/tyre combo so a bit of fabrication is definitely in order.

    And just so it is here, OEM Watsonian Monaco suspension, no brakes (not my picture, I have already dismantled my setup):

    Easy enough to convert to a modern torsion suspension but why when this one works just fine.

    Besides I still have all of this to put back together after I spend another $1,000.00 or so.

    After waiting almost 6 minutes months from the "mothership" for the suspension pivot I was able to put the Monza together: a basic motorcycle shock absorber and the stock drum (not linked) and wheel

    No idea on how or even if it will work, but here is my interpretation. They are air shocks that I found on Ebay, and I have about 6" and 4 1/2" of travel respectively. I like the idea of infinite spring rate settings, and since the shocks are exposed, little fingers can't be pinched.
    A significant testing program is part of the build process, and sometimes an angle grinder is the only remedy. :imaposer IMG_8415.jpg IMG_8414.jpg IMG_8416.jpg

    Adjustable ride hight/leveling , shock has spring preload adjustment as well as rebound & compression damping adjustment...

    Build thread is in my sig at the bottom...

    This is what I adapted for my current leaner set up.
    Ebay fournales shocks and modified Chiang Jiang earles forks I got cheap locally.
    ( need to redo the pivots as the bearings are tiny)
    It works very well as a leaner as it just seems to float alongside the bike.
    But I will I think at some stage if I can find my rountuit, convert back to a rigid outfit.
    The issue I found then is an anti swaybay is needed to stop excess leaning like in a Citroen 2CV.
    Excess lean generally seems to mess the steering geometry while turning and even with camber changes especially with a lot of suspension travel.

    Here's a picture of a pretty much standard trailing arm suspension with actuator from DMC--
