Dexys Midnight Runner?

Just wondering Danny at what angle does an ilean run out of function and default to the inside wheel only? I suspect it's well over any realistic angle you will ever get to and if that is the case you could widen the track with some bending and strengthening of the arms. A wider track will lower the angle at which it takes to the inner wheel but there may be enough leeway to go a bit wider to help stay upright easier at traffic lights etc.

A wheel brake anti-tilt mechanism will be more effective the wider you go too as you'd get more wheel movement for the same tilt. I'm only talking of adding an inch or two to each side.

Hi Popshot,
TBH I don't know, I have a feeling that the degree of tilt to get a wheel "lift" will be no less (and perhaps more) than you would see a 2-wheeled streamliner tilting on a bend. I have not decided whether to pursue this little "folly" yet because my right knee is a bit dodgy right now and I am not riding ANY of my machines, so making yet another seems a bit superfluous.

I like the concept of it, and it does appeal to me though.

In talking about it with Paul there are "options" to put an existing python front end on it, or make a new twisting chain FWD front half.

The jury is still out.

I did some measuring today with and without the tilt-damper/arrestor (definitely NOT a tilt-lock).
The pedals are almost in vertical opposition and that's an insane amount of tilt I think.

Rear view:

When you engage the tilt arrester the outside wheel starts to lift off after about 30°.
Whether it would still do that with all the rider's weight on the machine I cannot say (yet) because I could not hold the keel in place firmly AND push the thing over against the spring.

As Paul says, an i-lean is effectively a 3-wheeled 2-wheeler. The tilt arrester is just to ensure it stays more or less upright when the rider alights.
My crash-test-dummy suit in yellow & black is on order.

You aren't going to run out of lean and end up on two wheels with that to play with and if you do it's probably because you've already crashed.

There is absolutely no way I have suggested or sanctioned this !!!!

I cannot ride a 2 wheeled Python and when I tried this at home I never got off the front path.

My attempt at wide and tilt damping !

Sorry I must have misunderstood our "front-end" conversation.
Sanctioning stuff isn't in your remit anyway, so sanctioning anything is not possible.
No, you have never encouraged any implementation of an i-leaned too far and fell over. If anything your exhortations have been to avoid it at all cost.
We did discuss rear-ends having differing possible front-ends (e.g. Python/Twisted Chain) with a standard bolt-up interface though.

No-one is seeking to blame anyone for anything guvnor.

Yes and that is do-able and to me makes sense [ that don't mean much [ grandads ' make do and mend ']]

I am trying to preserve what little of your functioning body is left from further unnecessary injury and abuse.
A standard Python 2 wheeler has an almost vertical learning curve , then when you think it is master turns around and bites you hard !

Or posts have crossed in the ether, but all is good I think.

I had a two wheeled python and never rode for more than a few feet without falling. Clown bike is an apt phrase. Double chain front would be my choice for an ilean which would give the best chance of avoiding mishaps.
