Is there anyone who makes real fire-breathing motorized bicycles with antique or replica engines?
Therein is the problem really - of the available engines there's none that even vaguely look correct. If one were to spend the time to replicate a vintage boardtrack engine - I seriously doubt they'd bolt it to
any commercial bicycle & would most likely scratch build a frame & running gear as well. There
are folks whom would do just that, but now we're talking a nearly unlimited budget, fully stocked machine shops and the end result is most definitely not a "motorized bicycle" & it's essentially unusable as there's little to no chance of getting it street legal. I for one have little interest in such "trailer queens" and museum pieces beyond any cosmetic inspiration they may provide to build a daily driver.
Additionally, I don't know how much actual experience you've had with truly vintage engine styles - but I assure you the the Chinese two strokes do a pretty good job of emulating their "reliability" and maintenance needs at least lol
TBH, I think your taking it a bit too seriously & with an obvious bias. Few if any try to say their bikes are in fact "replicas" and I can't help but see it as complementary to the genre that so many do their best to emulate those madmen of old, to be "inspired" by such history... To use whatever resources they have at hand, to make the most of what they've got limited only by skills, time & budget. Which is
exactly the same methodology BTW.
This hobby is simultaneously both very old and quite new, the tech keeps changing and the style is as diverse as the people whom build them... if ya don't like what you see - innovate & build something better, perhaps others would be inspired by that too.
edit: Actually, digging around a bit I've been unable to find a pic of your motorized bicycle - couldja post an example of your "technological focus"? It may be best to create a new thread for your build as such innovation would be out of place in this'un
