Thanks for the info SM!
Funny you should mention the MXUS 3000w as I just recieved one in the mail a few days ago! (bought it back in march on the special sale at Kinaye Motors!)
You're exactly right, the Hubzilla is waaay overkill for it's current application, BUT! I plan on pushing it to it's Limits in the future.
I will be installing the MXUS 3000w on my Recumbent soon as I get my controller in, and I will most likely use it for my main transportation, however, the "E-Zilla" as we have come to calling this bike, is a joy to ride, and even thought it's a bit awkward to pedal (my legs are just a bit short for the reach lol) I can still work up a sweat if I want and go 28 MPH up-hill pulling a trailer full of tools!
I hope to start doing mobile repair/service for E-Bikes in town on it, just need to get some signs for the sides of the trailer!
I have no doubt that even the MXUS 3000w will be a bit overkill for my use, but that is the point, I want something that has high efficiency, low to no maintenance, (no more than a typical bicycle anyway) and something that can haul a trailer doing errands that I would normally only do with a car, all the while hauling most anything I need and not noticing the extra load, and climbing steep hills with out any noticeable heat/stress! I am thinking that 60V will be more than enough for the MXUS, and that is a more manageable battery size/power that will get me away from having to run LiPo, and into something like Lunacycle's 60V pack here:
