I know most these days seem to want to go the other direction, but my partner would like more gears on this heavy cargo bike that can be tough to pedal uphill. I think the frame has all of the necessary cable stops etc. for installing a front derailleur. And I know it would have to lose the chain guard.
But, I don't know much more than that. Like, is it possible to change the crankset to a 2 or 3 ring version? What else would have to be changed? What has to be compatible, and how do I make sure that it is?
I am pretty handy, and might consider doing at least some of the work myself if I can, and if it's even possible, but I don't know how to make sure it will all work together. And, if I can pick up components as I find good deals on them, that would be great too, so I need to know what to look for and what has to match, even if I'm going to have someone else put it all together.
I will do my best to provide additional information if it is needed. Thanks!
