Interesting idea .As the tilting part is on top of the fixed part you are always balanced on a knife-edge, I wonder what would be the effect of under-slinging the front section?
My take would be the knife edge means it's natural tendency is to want to leap to it's death either side rather than remain balanced ?
I assume by keeping it balanced I am expending some energy and brain power ? both of which are sadly lacking.
Your idea would in effect suspend me and the front end under the rear wheels thus naturally being balanced , only expending some energy when tilting and recovering ?] [ and no brain power involved Whew ]
However it would put the seat no longer over the elastomer/rod end bearing ? would that matter ?
not sure it will need 2 ? [ I know my idea ] thinking about it the whole affair will try to bend downwards at the single rod end thus forcing the elastomer into a compression mode ?As discussed, If there were 2 x Rod-ends and elastomers (tilt resistors) sandwiched between the fixed/tilting beams; would that work better?
