BigWheel, it's hard for anyone to tell you what kit to go with, since they don't know your conditions, planned usage, budget, etc. You miht be better off asking questions like, "Has anyone tried the LaShop 26" 48V 1000W hubmotor, what batteries did you use, how did it behave on hills/flatland, anything you particularly liked or disliked about it, etc.?" ....and then make up your own mind.
I am in the middle of the same search. Would like to get a 36V or 48V, 700 to 1000W hubmotor, haven't decided between internally-geared and non-geared. My bike is a Trek 7500 hybrid, so I'd like to get a 700c wheel. Unfortunately, none of the shops (maybe they are all one shop) in South El Monte has a 700c wheel, though a number of the Chinese ones (in Hong Kong, Guangzhue, etc. do offer 700c). I want to commute from home to work and back, 12 miles each way, 3/4 falt, a few hills. Will probably be running sealed lead-acid (SLA) batteries, which do not perform as well as LiFePO4 but weigh a LOT more. Have to do it due to budget constraints, I'll probably have 50 pounds of batteries on that poor bike plus my own 250# posterior. One reason I ride Treks is beause they are STRONG. Will probably use a front hubmotor, probably with disc brake for a load like that.
