No on a staight..
brake hard, bike pulls to the right, counter with a steer to the left, car lifts and only has to go above the COG to cause a flip. soft springs on the bike and no suspension on the car would also encourage this?
Also depending where its attached it could also affect the front or rear braking bias needed.
I'm starting to think that sidecars do actually make the bike inherently dangerous
Sidecars don't kill people, inappropriate braking kills people
Seriosuly, sidecar outfits are no more inherently dangerous than any other PTW. IF you ride like a nob, without respect for the machine or the road, you are going to get hurt. This is true of skateboards and Koeingseigg supercars and all points inbetween.
You would have to countersteer really hard to lift the chair in a straight line: it takes effort. A serious chair, like a Squire or a double-adult montrosity thing weighs A LOT. When you are braking hard, all the forces are acting to bring the whole vehicle /down/. Esp. with telescopic froks on the fornt.
Like I said, get a side-car brake. Makes the whole thing very controllable, and stops you much quicker. And you can do tricks like hoofing the thing round in it's own lenght
I'm finding it hard to explain, maybe because riding a chair is like riding a bike; once you get used to it, you just do it, without thinking about the mechanics of what you are doing.
Er, I do realise there are a lot of instructor type people around here who think very hard about what they are doing and how to explain it to other peeps. I'm just crap at that kind of thing.
Summary: they ain't dangerous unless you want to ride dangerously!
