Tripolar - a triple-pivot AWS / folding python trike

a triple-pivot folding python delta trike, with ~60 deg pivot angle. All-wheel steering is a bonus. Rear wheel steering is done by leaning into the corner and away from the seat, which is required for turning stability with this narrow-track trike and does take some learning. It is possible to turn by rear wheel steering only, and turning circle can be dizzy-tight with AWS. Going straight, front-wheel pedal steering disturbance seems to be compensated by the rear wheels. The spring between the rear wheels is needed to dampen wheel shimmy, perhaps some cargo will also help...

Una buena idea.

[@JohnAnderson-qg5fy]

Nice job!

Que entretenido..... Saludos

Could you make a video to just show how the rear wheel steering works?

[@miralovelovos]

genious

[@FutonExpress]

yes, if you mean the folding idea

[@namtuart]

Could that idea bu used for a side-by-side sociable?

[@FutonExpress]

not sure how much 2 riders side-by-side can tilt the frame/wheels...

[@FutonExpress]

see the wheels turn in at about 1:30

[@namtuart]

And how about the tilting steering in the back?

[@sweeney37]

What would happen if the front end was fixed ? so steering was all on rear perhaps via a lever ?

[@FutonExpress]

+Fryn the doctor Rear wheels are self centering but steering is not as natural as front wheel steering unless it can be set up to emulate similar performance. In this design the all wheels fold as well as steer...
