Hi, I live on a hill. I guess you can consider it a mountain. I'm not intending to do any mountain biking in the conventional sense, and I know the Nireeka bike is not meant for that, meaning it is really not designed for "off-roading". That said, my hill is probably around a 15 degree grade, and lasts about two miles. Its about 25 minutes of "granny gear" climbing on my current bike. Its all paved but I will need to climb it at the end of every outing. I weigh 160 pounds. I have heard that this type of requirement is better served by a mid-drive motor. Is there a reason why the Nireeka design team chose a hub-drive motor, versus a mid-drive? Will the standard Nireeka Homie be able to handle my hill on a daily basis? Will the 500 W motor suffice? Would I be better served by the 1000 W motor?
