Zen MBB Master
I have not seen it mentioned before (excuse me if it was), so here:
As far as I understand, this type of 'pedal steer' is completely independent on actual FORCE of pedalling (will happen if you spin with no load at all, as it is apparent on the video), but depends on distance from steering axis to cranks (gets greater with length, unlike 'conventional pedal steer' that gets less actually), mass of cranks and, above all, your *legs* and speed of cadence and I think length of cranks as well.
It seems like Ron's 'zero offset coaxial arrangement' has more merit that I've assumed: you want to minimise steering axis to BB distance as much as physically possible, provided you can stay within reasonable tiller length limits which, in turn, is also limited by your recline angle and steering axis inclination - due to the fact that making remote-steered MBB is a VERY hard task... if you want something with best handling characterises, that is.
