I have a DIY ebike with a 1200w rear direct drive hub motor and two 48v20ah batteries that I swap between manually (both batteries are attached and secured to the bike, I just unplug one from the controller and plug in the other when one gets low). I'm tempted to get a bafang front geared kit so I wouldn't have to swap between batteries and so I could get more torque up hills while using both motors and possibly have more range? I love the direct drive but I hate having to crawl up some of my steeper hills with all the cargo I sometimes carry at like 5mph while I spin away in my lower gears. It just feels wrong having the throttle maxed out while still peddling and only going walking speeds.
My main question is range, would I possibly get slightly better range by adding a geared motor up front and having both 20ah batteries split between the two motors if I use them right? If I used the geared motor for hills, the direct drive for flats, and both at once for steep hills, wouldn't I get better range being that I'm no longer stuck to having to push the direct drive to 100% all the time doing the thing it isn't suited for? I live in a very hilly area and usually have 5-10 pounds of cargo on the rear rack but sometimes up to 20-25 pounds.
