I have an idea and I'm wondering if it's feasible.
For an upcoming recumbent cargo touring build, I wonder if I could say use an 8-speed hub gear connected directly to an identical 8-speed hub gear, or three hub gears 4*4*4, to get logically 64 gears.
What sorts of problems might there be? I don't have any particular parts in mind regarding ratios, but does anyone do this?
Are there any good examples of how to do a high number of gears right?
The whole point of this would be to be able to drive the bike up anything from a long ridiculous 30% grade at walking pace to an easy 100km/h on a straightaway with fairing. Is that feasible using a large number of gears?
