I realize that there is another thread that features this type of bike, but that one was started originally as a market research thread. As the mini-velo appears to dominate that thread, I thought that maybe it was a good idea to spawn a thread that concentrated on nothing but minis. Think of this as a sort of community resource thread, so these questions are geared to inform/educate. Feel free to post new questions or answer .

1. What kind of max load are these things designed for?
2. Is it possible to run IGH with a coaster brake?
3. What about racks and fenders?
4. How readily available are tires/tubes?
