So I am seriously considering a hub mid drive to replace an outrunner for my next build, as I am currently having problems with snapping chains and tearing sprockets with my current build, the noise is tolerable, but I want something that is perfectly reliable.
So the reason I am avoiding a hub is the weight, currently the reduction for my 63-74 is well shy of 2kg all told, inc. motor (except crank/freewheel weight) and would take up a similar/smaller space to a hub motor. So as a result of the weight loss, I have a few kw in a bike well under 20kg, with 500wh of lifepo4. I am wanting a dual suspension, with lipo, and pretty sure I will be able to get the setup for under 6kg extra, but I hear that hub motors are very heavy, and the motor itself will be 6kg....
Never owned a hub, so don't know the weight for sure, but what would be the lightest hub that will push out 3-4kw? I am happy to overvolt it if it will handle it, just literally looking for the lightest way to get a hub running, so I can use all the hub motor components for reliability, and an off the shelf freewheel and bike chain going to the cranks. End result MUST be compact and clean.
Thanks for the input guys, I'm sure if there is a suitable motor out there, someone here knows it.
