<div>I used to think a Raleigh three-speed bike rear hub was about a complicated as a thing could get, that I could figure out, and I may have been right. Those things worked like Chinese arithmetic.</div>

<div>As to balancing a spoked wheel- it is difficult but not impossible to do without a college degree. We bent, loosened and broke bicycle spokes when kids and replaced them, and I have balanced and trued MGB wire wheels well enough to finish balance them
with lead weights like any other tire. When you are a kid with time to develop a "feel" for torque and tension, and can pay attention to cause and effect of adjustments, you can learn a lot on your own.</div>

<div>Dragging old tractors into this... I am a little surprised that no one ever designed a bicycle crank mechanism into a starter system for an old hand crank tractor.</div>
<div>There is an Amish shoe shop not far from here that the last I knew was still using a big old Landis out-sole stitcher that was still driven by a set of bicycle pedals. The operator sat on the seat and pedaled it which would be tricky because guiding the
shoe / boot takes about 3 hands itself.</div>
