Description

This is a 3D printable Mini Mountain bike that is roughly 1/6 scale of that of a kids bike. What makes this unique is the hubless rims and drive shaft. The rims and fork/handle bar are free to rotate. The crank is also free to rotate driving the rear wheel by a series of gears. A bevel helical ring gear on the crank drives the bevel helical pinion gear on the shaft drive. The miter gear on the shaft drives the pinion spur gear which then drives the main ring gear on the rear rim. As always and comments are welcomed, and likes are appreciated!
