History lesson: Alex Moulton (Moulton), Dr. David Hon (Dahon) and Andrew Ritchie (Brompton) all thought they'd designed amazing new bikes that would really change things. They all got patents to protect their IP. They all shopped their designs around to established bicycle manufacturers. They were all shown the door by those established bicycle manufacturers. They all raised the money to build the bikes themselves.
OTOH, Mark Sanders designed the Strida. And he got a patent. But he found a company to license the design and they found a company to build it (then another company built it, then another and then another).
I'm not being harsh, just realistic here: you seem to be unwilling to invest any money in pursing a patent, and you are definitely unwilling to invest any of your own money for manufacturing. Methinks you'll be able to tell your grandchildren you once designed a bike.
