![]() ![]() It's taken me until now to see that the steering works via caster as I could never get a good view of it in other pictures and videos. For any given corner you set the lean that is required for the speed you are going by pulling up /pushing down on the immovable bars and then you add in the amount of steering needed for that corner by pushing forward or pulling back on the bars and thus altering caster which equals steering due to the lean. Steering is completely separate from leaning with the exception that it can't steer at all without leaning which is of no importance. The more the upright is away from vertical the more a given amount of lean will steer. When the upright is vertical the lean induces no steering at all. The two silver bits at the ends of the main axle tube are linked through the tube so the both swivel together or not at all. The bars both either go forward together or back together. It's the ability to change the caster that allows this to steer. This effectively gives the option to change the caster. The silver ends to the axle boom are free to rotate. ![]() There's only so many ways you can move a bar mechanism (up / down and fore / aft in my example) and a twist cable adds another potential control function. As I intimated above perhaps a cable steered tilter is doable powered by a nuvinci shifter. Many people have made things I wouldn't and it doesn't necassarily make them wrong. It's not a path I'd do again (I tried this with the MK1). There is always the self-balanced option path to go down which may open other options up or shut some down. The only reason the steering link went ahead of the axle on the Mk2 was the tilting left zero room for it behind. There's just to much variation when you add suspension into the mix for steering linkages to cope with. Going upside down means suspension has to be forgone anyway. It's the forgoing of suspension that makes a tilter possible if you want the ability to control lean via a mechanism. This is very important as the bars coming towards you are a limiting factor and the bar pivot to backside distance must be as small as possible. Doing this reduces the amount the bars come in at you as you lift up / push down on them to tilt. ![]() I'd upside down the whole system to bring the handlebar pivot closer to my backside. The wishbones are replaced with a large upper member and a simple rod ended link at the bottom to enable the wheel tilt. Essentially the same system but upside down. ![]()
