The changing variable is wheel diameter. Is that going to matter?
Also, would there be a value to making this a front wheel drive bike?
Hey Tom, no,yes and no. Well technically you could copy and paste (if it were that easy) , but because of question two, there is your answer. Because of the wheel diameter differences between a mini bike and a bicycle, the gearing would not be desirable if just transfered over.
And what kind of value do you see in making a front wheel drive set-up? I can think of none and more of a pain than it would be worth. Just my opinions of course.
